lcd panel tn vs va supplier

Again, IPS is the clear winner here. The vertical viewing angles are very similar to the horizontal ones on both IPS and VA panels. Unfortunately, this is one area where TN panels are usually much, much worse. TN monitors degrade rapidly from below, and colors actually inverse - resulting in a negative image that can be distracting. For this reason, if you decide to buy a TN monitor, look for one with an excellent height adjustment, or consider buying a VESA mounting arm, as you should mount TN monitors at eye level. Even when mounted properly, larger TN displays can appear non-uniform at the edges.

There"s usually not much difference between VA and IPS panels in terms of gray uniformity. It"s rare for monitors to have uniformity issues, and even on monitors that perform worse than average, it"s usually not noticeable with regular content. TN monitors tend to perform a bit worse than usual, though, and the top half of the screen is almost always darker than the rest, but that"s an artifact of the bad vertical viewing angles.

Black uniformity tends to vary significantly, even between individual units of the same model, and there"s no single panel type that performs the best. It"s rare for monitors to have good black uniformity, and almost every monitor we"ve tested has some noticeable cloudiness or backlight bleed. IPS and TN panels can look slightly worse due to their low contrast ratios, as the screen can take on more of a bluish tint when displaying dark scenes. Like with contrast, black uniformity issues usually aren"t very noticeable unless you"re looking at dark content and you"re in a dark room. If you only use your monitor in a bright environment, generally speaking, you don"t need to worry about black uniformity.

Historically, TN panels used to have the worst colors, as many of them were cheaper models that only supported 6-bit colors or used techniques like dithering (FRC) to approximate 8-bit colors. Most displays today, including TN models, are at least 8 bit, and many of them are even able to approximate 10-bit colors through dithering. New technologies, like LG"s Nano IPS and Samsung"s Quantum Dot, add an extra layer to the LCD stack and have significantly improved the color gamut of modern IPS and VA displays, leaving TN a bit behind. Between them, NANO IPS is slightly better, as it tends to offer better coverage of the Adobe RGB color space. Although the difference is minor, IPS panels still have a slight edge over VA and TN displays.

Although TN panels have caught up a bit in the SDR color space, they"re far behind when it comes to HDR, so if you"re looking for a good HDR color gamut, avoid TN panels. Between VA and IPS panels, the difference isn"t as significant; however, IPS panels still have a slight edge. The best VA panels top out at around 90% coverage of the DCI P3 color space used by most current HDR content. IPS panels go as high as 98% coverage of DCI P3, rivaling even some of the best TVs on the market. Due to the very high coverage of DCI P3 on both VA and IPS, the difference isn"t that noticeable, though, as most content won"t use the entire color space anyway.

Although not necessarily as noticeable to everyone as the differences in picture quality, there can also be a difference in motion handling between IPS, VA, and TN displays. TN panels historically offered the best gaming performance, as they had the highest refresh rates and extremely fast response times. Manufacturers have found ways to drastically improve the motion handling of VA and IPS panels, though, and the difference isn"t as pronounced.

LCD panel technology has changed drastically over the last few years, and the historical expectations for response time performance don"t necessarily hold anymore. For years, TN monitors had the fastest response times by far, but that"s started to change. New high refresh-rate IPS monitors can be just as fast.

VA panels are a bit of a strange situation. They typically have slightly slower response times overall compared to similar TN or IPS models. It"s especially noticeable in near-black scenes, where they tend to be significantly slower, resulting in dark trails behind fast-moving objects in dark scenes, commonly known as black smear. Some recent VA panels, such as the Samsung Odyssey G7 LC32G75T, get around it by overdriving the pixels. It results in much better dark scene performance but a more noticeable overshoot in brighter areas.

Within each of the three types of LCD we mentioned, other related panel types use the same basic idea but with slight differences. For example, two popular variants of IPS panels include ADS (technically known as ADSDS, or Advanced Super Dimension Switch) and PLS (Plane to Line Switching). It can be hard to tell these panels apart simply based on the subpixel structure, so we"ll usually group them all as IPS, and in the text, we"ll usually refer to them as IPS-like or IPS family. There are slight differences in colors, viewing angles, and contrast, but generally speaking, they"re all very similar.

There"s another display technology that"s growing in popularity: OLED. OLED, or organic light-emitting diode, is very different from the conventional LCD technology we"ve explored above. OLED panels are electro-emissive, which means each pixel emits its own light when it receives an electric signal, eliminating the need for a backlight. Since OLED panels can turn off individual pixels, they have deep, inky blacks with no blooming around bright objects. They also have excellent wide viewing angles, a near-instantaneous response time, and excellent gray uniformity.

OLED panels aren"t perfect, though. There"s a risk of permanent burn-in, especially when there are lots of static elements on screen, like the UI elements of a PC. There aren"t many OLED monitors available, either, but they"ve started to gain popularity as laptop screens and for high-end monitors, but they"re very expensive and hard to find. They"re also not very bright in some cases, especially when large bright areas are visible on screen. The technology is still maturing, and advances in OLED technology, like Samsung"s highly-anticipated QD-OLED technology, are promising.

As you can probably tell by now, no one panel type works best for everyone; it all depends on your exact usage. Although there used to be some significant differences between panel types, as technology has improved, these differences aren"t as noticeable. The two exceptions to this are viewing angles and contrast. If you"re in a dark room, a VA panel that can display deep blacks is probably the best choice. If you"re not in a dark room, you should focus on the other features of the monitor and choose based on the features that appeal to your exact usage. IPS panels are generally preferred for office use, and TN typically offers the best gaming experience, but recent advancements in VA and IPS technology are starting to change those generalizations. For the most part, the differences between each panel type are so minor now that it doesn"t need to be directly factored into your buying decision.

So, why would anyone ever buy a TN panel? For starters, they’re cheap. They don’t cost a lot to produce, so they’re often used in the most budget-friendly options. If you don’t value color reproduction or need excellent viewing angles, a TN panel might be fine for your office or study.

TN panels also have the lowest input lag—typically around one millisecond. They can also handle high refresh rates of up to 240 Hz. This makes them an attractive option for competitive multiplayer games—especially eSports, where every split-second counts.

IPS technology was developed to improve upon the limitations of TN panels—most notably, the poor color reproduction and limited viewing angles. As a result, IPS panels are much better than TNs in both of these areas.

In particular, IPS panels have vastly superior viewing angles than TNs. This means you can view IPS panels from extreme angles and still get accurate color reproduction. Unlike TNs, you’ll notice very little shift in color when you view one from a less-than-ideal perspective.

IPS panels are also known for their relatively good black reproduction, which helps eliminate the “washed out” look you get with TN panels. However, IPS panels fall short of the excellent contrast ratios you’ll find on VAs.

While high refresh rates were typically reserved for TNs, more manufacturers are producing IPS panels with refresh rates of 240 Hz. For example, the 27-inch 1080p ASUS VG279QM uses an IPS panel and supports 280 Hz.

Previously, TNs exhibited less input lag than any other panel, but IPS technology has finally caught up. In June 2019, LG announced its new Nano IPS UltraGear monitors with a response time of one millisecond.

Despite the gap being closed, you’ll still pay more for an IPS panel with such a low response time than you would for a TN with similar specs. If you’re on a budget, expect a response time of around four milliseconds for a good IPS monitor.

One last thing to be aware of with IPS panels is a phenomenon called “IPS glow.” It’s when you see the display’s backlight shining through it at more extreme viewing angles. It’s not a huge problem unless you view the panel from the side, but it’s something to keep in mind.

VA panels are something of a compromise between TN and IPS. They offer the best contrast ratios, which is why TV manufacturers use them extensively. While an IPS monitor typically has a contrast ratio of 1000:1, it’s not unusual to see 3000:1 or 6000:1 in a comparable VA panel.

In terms of viewing angles, VAs can’t quite match the performance of IPS panels. Screen brightness, in particular, can vary based on the angle from which you’re viewing, but you won’t get the “IPS glow.”

VAs have slower response times than TNs and the newer Nano IPS panels with their one-millisecond response rates. You can find VA monitors with high refresh rates (240 Hz), but the latency can result in more ghosting and motion blur. For this reason, competitive gamers should avoid VA.

Compared to TNs, VA panels do offer much better color reproduction and typically hit the full sRGB spectrum, even on lower-end models. If you’re willing to spend a bit more, Samsung’s Quantum Dot SVA panels can hit 125 percent sRGB coverage.

For these reasons, VA panels are seen as the jack of all trades. They’re ideal for general use, but they either match or fall short in most other areas except contrast ratio. VAs are good for gamers who enjoy single-player or casual experiences.

When compared to CRT monitors, all LCD panels suffer from some form of latency issue. This was a real problem when TN panels first appeared, and it’s plagued IPS and VA monitors for years. But technology has moved on, and while many of these issues have been improved, they haven’t been eliminated entirely.

Uneven backlighting is another issue you’ll find on all panel types. Often this comes down to overall build quality—cheaper models slack on quality control to save on production costs. So, if you’re looking for a cheap monitor, be prepared for some uneven backlighting. However, you’ll mostly only notice it on solid or very dark backgrounds.

LCD panels are also susceptible to dead or stuck pixels. Different manufacturers and jurisdictions have different policies and consumer laws covering dead pixels. If you’re a perfectionist, check the manufacturer’s dead-pixel policy before you buy. Some will replace a monitor with a single dead pixel for free, while others require a minimum number.

Office or study use: Your budget should be your primary concern here. VA is the do-it-all panel, with superior viewing angles to TN, but either would do the trick. You can save some money because you don’t need high refresh rates or ultra-low latency. They’re still nice, though. You’ll see a noticeable difference in smoothness just when moving the Windows cursor on a monitor with a 144 versus 60 Hz refresh rate.

Photo and video editors/Digital artists: IPS panels are still generally favored for their ability to display a wide gamut of colors. It’s not unusual to find VA panels that also cover a wide gamut (125 percent sRGB, and over 90 percent DCI-P3), but they tend to exhibit more motion blur during fast-paced action than IPS panels. If you’re serious about color accuracy, you’ll need to properly calibrate your monitor.

Programmers who mount monitors vertically: You might think TN panels are great for programmers, but that’s not necessarily the case. TN panels have particularly bad viewing angles on the vertical axis. If you mount your monitor in portrait mode (as many programmers and mobile developers do), you’ll get the worst possible viewing angles from a TN panel. For the best possible viewing angles in this scenario, invest in an IPS display.

Competitive online gamers: There’s no question TN panels are still favored in the eSports world. Even the cheapest models have fast response times and support for high refresh rates. For 1080p gaming, a 24-inch will do just fine, or you could opt for a 1440p, 27-inch model without breaking the bank. You might want to go for an IPS panel as more low-latency models hit the market, but expect to pay more.

Non-competitive, high-end PC gamers: For a rich, immersive image that pops, a VA panel will provide a higher contrast ratio than IPS or TN. For deep blacks and a sharp, contrasting image, VA is the winner. If you’re okay with sacrificing some contrast, you can go the IPS route. However, we’d recommend avoiding TN altogether unless you play competitively.

Best all-rounder: VA is the winner here, but IPS is better in all areas except contrast ratio. If you can sacrifice contrast, an IPS panel will provide fairly low latency, decent blacks, and satisfactory color coverage.

If you can, check out the monitor you’re interested in in-person before you buy it. You can perform some simple ghosting and motion blur tests by grabbing a window with the mouse and moving it rapidly around the screen. You can also test the brightness, watch some videos, and play with the onscreen display to get a feel for it.

First, to be clear, there is no “best” panel type out of these, as all have their respective advantages and disadvantages over the others. The information here pertains to general characteristics, as even panels of the same panel type will have some variance in characteristics (power consumption, backlight bleed, etc.) depending on the luck of the draw. Manufacturer tuning can also impact display output, affording some differentiating leverage to manufacturers sourcing from panel suppliers (which is effectively all of them).

The earliest widely available and used consumer PCs employed CRT (Cathode Ray Tube) monitors. For this reason, CRT monitors are oftentimes remembered in fondness (or contempt) by those who grew up using them.

Nostalgia or riddance aside, there are still some valid reasons to use a CRT monitor. When compared to LCD panels, CRT monitors can have higher contrast ratio, very low response time (which leads to non-blurred pictures even with fast movement on screen), and very little input lag, although LCD input lag can be largely negated. The downsides of CRTs are apparent, though: they’re large, heavy, consume more power, produce flicker, can produce audible, high frequency noise (although age plays into whether one can hear them or not), produce slightly distorted images, and produce harmful electromagnetic waves (in the form of x-rays), which requires that toxic materials such as lead and barium must be used as shielding to prevent detrimental health effects. CRT monitors are also notoriously hazardous to repair, given their large, active electrical coils that can measure upwards of 50,000 volts of electricity.

CRT displays are sometimes still used in medical, simulation, military, and government fields that have embedded the displays into control panels and machinery.

CRT monitors have largely gone out of production, and are rarely sold new (finding a used CRT is fairly easy), but their advantages temporarily lent themselves to some special uses. In regards to gaming, CRT monitors have historically been advantageous to use when gaming competitively due to very little motion blur and very little input lag. That being said, these advantages have faded with the progressive march of TN panels.

TN panels now have low motion blur (especially with lightboost or a similar technology), offer high refresh rates, low response times (1ms GTG in many cases), and are more than adequate even in the world’s most competitive games.

Ultimately, for the vast majority of users, the disadvantages of CRTs aren’t worth their limited gains, especially when TN panels meant for gaming more than adequately satisfy the needs of even competitive gamers.

TN panels have many benefits over the previously popular CRT monitors: lower weight, lower cost to produce, lower power consumption, they’re much thinner, offer clearer pictures, have no realistically achievable resolution limits, offer flexibility in size and shape, and the ability to eliminate flicker.

That being said, TN panels weren"t and still aren’t perfect, and compared to the previously popular CRT monitors, they’ve suffered from limited viewing angles, uneven backlighting, worse motion blur, higher input lag, dead/stuck pixels, and poor display in sunlight.

To be clear, many of these issues have been improved upon, but due to the underlying science of LCD TN panels, cannot be completely resolved. In fact, many of these issues -- like uneven backlighting, motion blur, input lag, and dead/stuck pixels -- are inherent issues across all LCD panel types. Poor viewing angles become a more pressing issue with larger displays, since the viewing angle when viewed straight on increases towards the outside of the monitor, thus causing more color distortion. TN panels do have the advantages of lower response times and higher refresh rates than other panel types/CRTs. TN panels are generally from 60Hz to 144Hz, offering substantially greater fluidity of gameplay with higher frequencies.

TN panels provide a good compromise between CRTs and other LCD panels as their traditionally low response rates, input lag, and high refresh rate make them comparable to CRTs for accuracy; TN panels also have the advantages of offering sharper pictures, widescreen output, lower weight, smaller physical dimensions, and higher resolutions compared to CRTs.

Still, compared to other LCD panels, TN panels suffer from poor viewing angles and worse color reproduction. Ultimately, for most gamers playing somewhat competitively to very competitively, TN panels are a good choice, but for those looking for a prettier and improved color experience, another panel type may be worth considering.

IPS (In-Plane Switching) was created to address the shortcomings of TN panels. IPS panels seek to solve TN panels’ issues of poor color reproduction and viewing angles. In this regard, IPS panels have largely succeed. Not only do they offer a higher contrast ratio (superior blacks), high color accuracy (which leads to IPS panels also generally looking less “washed out”), but IPS panels also have very little color shift when changing the viewing angles.

The tradeoff to this is that IPS panels have slower response times, higher production costs, higher power consumption, and lower possible refresh rates. IPS panels have traditionally been 60Hz, although, as with all monitors, they can be overclocked (results will vary). There have been improvements to IPS panels over the years, and slightly different revisions in the form of E-IPS and H-IPS, but ultimately the differences between these versions are inconsequential to gamers and those not involved in graphic design as a job.

Due to their worse response rates and lower possible refresh rates, IPS panels are generally considered to be worse for competitive gameplay and used more often when color is important, such as graphic design. For gamers who don’t play competitively and prefer breathtaking strolls in Skyrim instead of sweeping scrubs in CS:GO, an IPS panel should be a consideration for the next monitor.

PLS (Plane to Line Switching) are quite similar to IPS panels, so much so that they have the same advantages and disadvantages, with a couple extra minor advantages. PLS is produced by Samsung, who claims that compared to IPS panels, PLS panels have better viewing angles, a 10% increase in brightness, 15% decrease in production costs, increased image quality, and allow for flexible panels. Samsung’s PLS panels have been known to overclock well in monitors such as the QNIX 2710 in particular. Overall, PLS is basically Samsung’s version of IPS, as it is very similar in functionality (and even name). AHVA is also very similar to IPS and PLS, and differentiation between them is rare, although it should not be confused with the next panel type.

VA (Vertical Alignment) panels offer a solid medium between TN and IPS panels. VA was created to combine the advantages of IPS and TN panels, and largely did, although they did so with some compromise. That seems to be a theme in the world of monitors.

Compared to IPS panels, VA panels have the advantage of higher possible refresh rates. Although most are currently 60Hz, there are a few that are above 60Hz. VA has more advantages over TN panels than IPS, with better color reproduction, higher maximum brightness, and better viewing angles. VA panels do have the best contrast ratios of all panel types mentioned, but they also have the worst response times of the monitor technologies covered here. This causes blurring in fast-moving pictures and is disadvantageous to gaming.

For the use of gaming, VA is not the greatest option due to generally higher response time in comparison to other panel types; this slower response causes more motion blur, effectively eliminating its deployment for fast-moving titles. For a general work monitor, VA panels provide high contrast ratios, brightness, refresh rates, good color reproduction, and good viewing angles.

TN panels are another good choice for competitive gamers, as they support higher refresh rates, low response times, decent input lag, and high resolutions. Their bad viewing angles, color reproduction, and slight blurring compared to CRT monitors (due to higher response times) are all disadvantages, ones which cannot be easily fixed.

IPS panels solve the issues of TN panels, with better color reproduction and viewing angles, but do so at the cost of refresh rate and response time. IPS panels are especially useful for those not wanting to play too competitively, but want a beautiful/immersive visual experience. PLS and AHVA are similar enough to IPS to usually not be differentiated.

VA panels provide a good middle ground with better-than-IPS refresh rates and contrast levels, but have worse viewing angles and color production, although generally still better than TN. Response times are VA’s largest downfall, though, being slower than IPS and its variants and TN.

What’s best for you will depend on all of these items. For those wanting to play at a competitive level and who favor FPS or racing games, TN panels are best. Those wanting a more impressive and immersive experience may want an IPS (or similar variant, such as PLS), especially if working on artistic endeavors. Finally, those wanting a general monitor for work might consider a VA panel, although due to their higher response times, they won’t be good for gaming.

By far the most common types of display panels used on PC monitors are TN, IPS and VA. We"re sure you"ve heard these terms before if you"ve researched monitors to purchase, and to be clear, the type of panel is a key piece of information that reveals a lot about how the monitor will behave and perform.

TN is the oldest of the LCD technologies and it stands for twisted nematic. This refers to the twisted nematic effect, which is an effect that allows liquid crystal molecules to be controlled with voltage. While the actual workings of a TN-effect LCD are a little more complicated, essentially the TN-effect is used to change the alignment of liquid crystals when a voltage is applied. When there is no voltage, so the crystal is "off," the liquid crystal molecules are twisted 90 degrees and in combination with polarization layers, allow light to pass through. Then when a voltage is applied, these crystals are essentially untwisted, blocking light.

VA, stands for vertical alignment. As the name suggests, this technology uses vertically aligned liquid crystals which tilt when a voltage is applied to let light pass through. This is the key difference between IPS and VA: with VA, the crystals are perpendicular to the substrates, while with IPS they are parallel. There are several VA variants, including Samsung"s SVA and AU Optronics AMVA.

IPS stands for in-plane switching and, like all LCDs, it too uses voltage to control the alignment of liquid crystals. However unlike with TN, IPS LCDs use a different crystal orientation, one where the crystals are parallel to the glass substrates, hence the term "in plane". Rather than "twisting" the crystals to modify the amount of light let through, IPS crystals are essentially rotated, which has a range of benefits.

There are many IPS variants on the market, with each of the three big LCD manufacturers using a different term to describe their IPS-type technology. LG simply calls their tech "IPS" which is easy for everyone. Samsung uses the term PLS or plane-to-line switching, while AU Optronics uses the term AHVA or advanced hyper viewing angle. AHVA shouldn"t be confused with regular VA displays, it"s an annoying and confusing name in my opinion, but AHVA is an IPS-like technology. Each of LG"s IPS, Samsung"s PLS and AUO"s AHVA are slightly different but the fundamentals are rooted in IPS.

So in summary, TN panels twist, IPS panels use a parallel alignment and rotate, while VA panels use a vertical alignment and tilt. Now let"s get into some of the performance characteristics and explore how each of the technologies differ and in general, which technology is better in any given category.

By far the biggest difference between the three technologies is in viewing angles. TN panels have the weakest viewing angles, with significant shift to color and contrast in both the horizontal and especially vertical directions. Typically viewing angles are rated as 170/160 but realistically you"ll get pretty bad shifts when viewing anywhere except for dead center. Higher-end TNs tend to be somewhat better but overall this is a big weakness for TNs.

VA and IPS panels are both significantly better, with IPS being the best overall for viewing angles. 178/178 viewing angle ratings are a realistic reflection of what you can expect with an IPS, you won"t get much shift in colors or contrast from any angle. VAs are good in this regard but not as good as IPS, mostly due to contrast shifts at off-center angles. With VAs and especially TNs having some color and contrast shifts when viewing at angles, they"re not as well suited to color-critical professional work as IPS panels, which is why you see most pro-grade monitors sticking to IPS.

In terms of brightness there"s no inherent differences between the technologies because the backlight, which determines brightness, is separate to the liquid crystal panel. However there are significant differences to contrast ratios, and this an area most people look at when determining which panel type they want.

Both TN and IPS panels tend to have a contrast ratio around 1000:1, although in my testing I have noted some differences. TN panels tend to have the lowest contrast ratios when calibrated, with an entry-level panel sitting between 700:1 and 900:1 and good panels pushing up to that 1000:1 mark. IPS has a larger range, I"ve seen some as low as 700:1 like TNs, however the very best tend to push up higher than TN, with 1200:1 as the upper range for desktop monitors and some laptop-grade displays reaching as high as 1500:1.

Neither TN nor IPS get to the range of VA though. Entry-level VA panels start with a contrast ratio of 2000:1 from those that we"ve tested, with the best easily exceeding 4500:1, although 3000:1 is a typical figure for most monitors.

TVs make extensive use of VA panels and there contrast ratios can be even higher. It"s not unusual to see over 6000:1. So if you want deep blacks and high contrast ratios, you"ll need to go with something VA.

While IPS panels tend to be a middle ground for contrast they do suffer from a phenomenon called "IPS glow," which is an apparent white glow when viewing dark imagery at an angle. The best panels exhibit minimal glow but it"s still an issue across all displays of this type.

Color quality is another difference many people cite between TN displays and other display panels in particular. And this can be split into two categories: color depth or bit depth, and color gamut.

In both of these regards, TN panels tend to fall on the weaker end of the scale. Many TN displays, in particular entry-level models, are only natively 6-bit and use frame rate control, otherwise called FRC or dithering, to achieve standard 8-bit output. 6-bit panels are prone to color banding, while native 8-bit panels have smoother color gradients and therefore better color output.

Not all TN panels are 6-bit. The top-end TNs are native 8-bit, but it"s safe to say most TNs will only be native 6-bit, even today. If you are after a native 8-bit display, you"ll need to go with either IPS or VA, where many more panels come native 8-bit.

As for native true 10-bit, typically you"ll need to look for an IPS panel, which make up the majority of native 10-bit panels. Some VA panels can do it, but they are rare. Most displays you purchase that claim to be 10-bit, are actually 8-bit+FRC, with only high-end professional-grade monitors offering a native 10-bit experience.

This is another area where VA and IPS provide a superior experience. The best TN panels tend to be limited to sRGB, or in the case of the worst entry-level panels, don"t even cover the entirety of the sRGB gamut. Wide-gamut TN panels do exist, but they are rare.

VA panels typically start with full sRGB coverage as a minimum, and depending on the panel can push higher. VAs that use a quantum dot film, typically from Samsung, offer higher gamuts, around the 125% sRGB or 90% DCI-P3 mark. Most of the wide gamut VA monitors we"ve tested fall between 85 and 90% DCI-P3 coverage, which is a decent result, though the best can approach 95% or higher.

With IPS panels, there is the largest variance. Entry-level IPS displays tend to offer 95% sRGB coverage or less, while the majority stick to full sRGB coverage. Then with high-end displays, usually for professionals, it"s not unusual to see full DCI-P3 and Adobe RGB coverage. Of all the wide gamut IPS displays I"ve tested, the lowest DCI-P3 coverage I"ve seen has been 93%, with over 95% a typical figure. This makes IPS the best technology for wide gamut work.

Throughout most of this discussion we"ve been talking about TN as the worst of the three technologies. So far, it has the worst color reproduction, contrast ratios and viewing angles. But it does have one key advantage, and that comes in the form of speed. TN panels have historically been the best for both refresh rates and response times, however that trend is slowly changing for the better.

Not long ago, we argued that only with a TN panel it was possible to hit 240 Hz, doing so at 1080p and later up to 1440p. Most recently, however we"ve seen IPS monitors hit the highest mark ever for a consumer-grade gaming monitor at 360Hz, and do so very convincingly. We"re sure other monitors will follow but as of writing, the Asus ROG Swift PG259QN can deliver both the fastest response times and an accurate color experience using an IPS panel.

More mainstream monitors using IPS panels tend to range from the regular 60Hz for productivity, up to 165 Hz and 240 Hz depending on the market they"re aimed at. VA panels top out at around 240 Hz at the moment.

Most IPS displays, especially high-grade options for professionals, as well as entry-level office monitors, are either 60 or 75 Hz. Meanwhile, a significantly larger number of VA panels across a wider range of sizes and resolutions are high-refresh, while the big selling point of TN is its super high refresh capabilities.

Another major consideration is response times, which govern the level of ghosting, smearing and overall clarity of a panel. Early IPS and VA panels were very slow, however this has improved a lot with modern panels, so the differences between the three technologies aren"t as pronounced as they once were. TN still holds an advantage here.

Most TN panels have a rated transition time of 1ms, or even lower with some recent releases. Actual grey to grey averages we"ve measured for TN panels tend to be in the 2-3 ms range when overdrive is factored in, which makes TN the fastest technology.

IPS panels are next in terms of speed, though as tends to be the case with IPS, there is a wide variance between the best and worst of this type. High-end IPS monitors, typically those with high refresh rates, can have a transition time as fast as 3ms. Compared to the best TN panels, this still makes IPS slower. However entry-level IPS panels or those without overdrive sit closer to the 10ms range, while mid-tier options tend to occupy the 5 to 7 ms bracket.

VA panels are consistently the slowest of the three types, but again, high-end gaming monitors have been pushing this further on every generation. The absolute fastest VA panel we"ve measured so far has a 4ms response time which is very impressive, though more typical numbers are between 8 and 10 ms for gaming monitors. VA panels also tend to be less consistent with their transitions; some individual transitions can be fast, while others very slow, whereas IPS panels tend to hover more around their overall grey to grey average.

While a lot of people are unlikely to spot the difference between an 8ms VA panel and a 5ms IPS, TN panels overall tend to be noticeably clearer in motion, but that gap is closing with every generation. The slowness of VA panels also limits their real world refresh rate: a 144 Hz panel that only manages a 9ms response time, is actually delivering an image most equivalent to a 110 Hz panel. Whereas most 144 Hz IPS panels can transition faster than the 6.94ms refresh window, leading to a true 144 Hz experience. So that"s something to consider.

As a quick summary, TN panels are the fastest and have the highest refresh rates, however they have the worst viewing angles by far, as well as weak color performance and typically the lowest contrast ratios. TNs are typically used for ultra-fast gaming displays, as well as budget class displays, for both desktop monitors and laptops.

IPS is a middle-ground technology. They typically have the best color performance and viewing angles, mid-tier response times and refresh rates, along with mid-tier black levels and contrast ratios. Due to its top-end color output, IPS panels are the go-to choice for professionals, but you"ll also find them in entry-level displays, office monitors, most laptops and a handful of gaming monitors.

VA panels are the slowest of the three, but have the best contrast ratio and black levels by far. Color performance isn"t quite at the level of IPS, but they still offer a significantly better experience than TN in this regard.

With response times for the best modern VAs approaching the level of a typical IPS, along with broad support for high refresh rates, VA monitors are commonly used for gaming monitors. Entry-level VAs also tend to be superior to entry-level TN and IPS panels, though you won"t find VA used in laptops.

There"s no right answer to which monitor technology is best, because all have their strengths and weaknesses which is why all three coexist on the market today. However if you want our recommendation, we tend to gravitate towards VA panels for most buyers, especially gamers and those after something entry-level. Creative professionals should be looking exclusively at IPS monitors, while those after something dirt cheap or ultra high refresh for competitive gaming should opt for TN, although superior latest-gen IPS and VA offerings are finally matching or even beating the best of TN in some regards.

When choosing a new computer monitor, the type of panel used by the display is a key piece of information that reveals a lot about how the monitor will behave and perform. By far the most common types of display panels are TN, IPS and VA.

Monitor LCD panels are made up of many layers, including a backlight, polarizing filters and the liquid crystal layer. It"s this liquid crystal layer that determines the intensity of light let through from the backlight, and in what colors, whether red, green or blue. To control this intensity, a voltage is applied to the liquid crystals, which physically moves the crystals from one position to another. How these crystals are arranged and how they move when voltage is applied, is the fundamental difference between TN, VA and IPS.

Our original explainer about display technology and the difference between TN vs. VA vs. IPS was published almost three years ago, and while most of that information remains accurate to this day, we"ve seen the introduction of much faster IPS displays as well as a revolutionary updates to VA panels, particularly from Samsung Odyssey gaming monitors. We"ve also since tested over 100 monitors, so we have a lot more insights to share about performance.

TN is the oldest of the LCD technologies and it stands for twisted nematic. This refers to the twisted nematic effect, which is an effect that allows liquid crystal molecules to be controlled with voltage. While the actual workings of a TN-effect LCD are a little more complicated, essentially the TN-effect is used to change the alignment of liquid crystals when a voltage is applied. When there is no voltage, so the crystal is "off," the liquid crystal molecules are twisted 90 degrees and in combination with polarization layers, allow light to pass through. Then when a voltage is applied, these crystals are essentially untwisted, blocking light.

VA, stands for vertical alignment. As the name suggests, this technology uses vertically aligned liquid crystals which tilt when a voltage is applied to let light pass through. This is the key difference between IPS and VA: with VA, the crystals are perpendicular to the substrates, while with IPS they are parallel.

IPS stands for in-plane switching and, like all LCDs, it too uses voltage to control the alignment of liquid crystals. However unlike with TN, IPS LCDs use a different crystal orientation, one where the crystals are parallel to the glass substrates, hence the term "in plane". Rather than "twisting" the crystals to modify the amount of light let through, IPS crystals are essentially rotated, which has a range of benefits.

There are various subvariants to these technologies which can tweak things further, and you"ll also see different brand names depending on the panel manufacturer. For example, AU Optronics use "AHVA" to refer to an IPS-type panel, not a VA panel. Samsung use PLS, while brands like LG simply use "IPS". Then on the VA side we have AU Optronics "AMVA" and Samsung"s "SVA" among others.

So in summary, TN panels twist, IPS panels use a parallel alignment and rotate, while VA panels use a vertical alignment and tilt. Now let"s get into some of the performance characteristics and explore how each of the technologies differ and in general, which technology is better in any given category.

The most immediately obvious difference when viewing a TN, IPS or VA panel for the first time is in viewing angles. This is one area that hasn"t significantly changed since the introduction of these technologies.

TN panels have the weakest viewing angles, with significant shift to color and contrast in both the horizontal and especially vertical directions. Typically viewing angles are rated as 170/160 but realistically you"ll get pretty bad shifts when viewing anywhere except for dead center. Higher-end TNs tend to be somewhat better but overall this is a big weakness for TNs and can impact the experience for productivity where any shifts to color impact accuracy for things like photo editing.

VA and IPS panels are significantly better for viewing angles, with IPS panels generally giving the best overall experience. Here you"ll commonly see 178/178 ratings for viewing angles, and while there can still be some shift to colors and brightness viewing at off-center angles, this will be far less noticeable than on a TN panel. Of all the IPS panels we"ve reviewed over the years, I"d describe the majority of them as having excellent viewing angles, a non-issue for modern IPS displays.

VAs are also good but not as good as IPS and can have a greater degree of contrast shifting than IPS. But the thing that impacts VA viewing angles more than this is the fact that many VA monitors today are curved, and any introduction of a curve reduces viewing angles. That"s something to keep in mind when choosing between IPS and VA

Because the liquid crystal layer is separate to the backlight layer, there is no technical reason why TN, IPS or VA monitors should differ in terms of brightness. Across the 100 displays we"ve tested using our latest test suite, the average SDR brightness for IPS panels was 385 nits, versus 367 nits for TN and 346 nits for VA - so really there"s not much of a difference.

Contrast ratio, on the other hand, is where another major difference occurs. TN panels have the worst contrast ratios, with the twisting technique not particularly great at producing deep blacks. In the best cases you"ll see contrast ratios around 1000:1, but typically after calibration these numbers are lower, in the 700:1 to 900:1 range. Of the monitors we"ve tested, the average TN has a contrast ratio of 872:1, which is poor so if you want rich, beautiful blacks - well maybe just buy an OLED but if you"re buying LCD, don"t get a TN.

IPS is the next step up, though generally IPS contrast ratios aren"t that different from TN. In the worst cases - in particular LG"s current line-up of Nano IPS panels - you won"t see contrast performance any different from a typical TN, with a ratio below 1000:1. However outside of those worst cases, it"s much more common to see contrast at or above 1000:1, with some best case examples pushing up to 1500:1 which is about the ceiling I"ve seen for IPS. Of the IPS panels we"ve tested, an average contrast ratio of 1037:1 was recorded, 19% higher than the average contrast of a TN.

If you really want an LCD to produce deep blacks though, you"ll have to go with a VA panel. The design of these panels is much more conducive to great contrast ratios, which typically start at 2000:1, higher than even the best IPS alternatives.

We"ve measured ratios up to 5000:1 for VAs, and some TVs can push this even higher. The range of typical contrast ratios is also quite a bit larger than with the other two technologies, but when manufacturers list a 3000:1 ratio for their VA monitor they"re usually correct - on average we measured a 2898:1 contrast ratio for VAs. With that in mind you can see VAs are usually 2.5 to 3 times better at producing blacks than IPS or TN, great for night scenes.

We often get asked whether these differences in contrast ratios actually matter. Almost all monitors use some sort of matte anti-glare coating, which can reduce the effective contrast ratio in brighter viewing environments. So if you"re using your monitor during the day, or under artificial lights, the difference between TNs, IPSs and VAs in contrast ratio is going to be less noticeable. But if you typically use your monitor in a dimmer environment, like gaming with the lights off or having a cheeky late night incognito browser session, you"ll much more easily spot the massive superiority VAs have in this area.

It"s also worth mentioning that while IPS panels tend to be a middle ground for contrast they do suffer from a phenomenon called "IPS glow," which is an apparent white glow when viewing dark imagery at an angle. The best panels exhibit minimal glow but it"s still an issue across all displays of this type, and can vary between individual units.

Before when discussing TN vs. VA vs. IPS, we spent some time talking about the differences between TNs, VAs and IPS in terms of bit depth -- or the difference between 6-bit, 8-bit and 10-bit panels. But we feel this is less relevant these days when the vast majority of displays are native 8-bit panels, with the exception of a few low-end panels that are 6-bit, and a few professional grade high-end panels that are 10-bit.

It remains the case that most displays advertised as "10-bit" or having "1 billion colors" are not true 10-bit panels, instead achieving this through FRC or dithering, and the type of LCD panel technology makes little difference.

There also isn"t a significant difference these days between LCD types when it comes to coverage of "standard" color spaces like sRGB or Rec. 709, which is used by default in Windows and is widely used for video content.

Even TN panels, which historically have had the "worst" color quality, these days will cover over 95% of the sRGB color space at a minimum for any monitor worth buying. The exceptions to this are entry-level junk some OEMs like to punish their low-end laptop buyers with; it"s rare for a desktop monitor to go below 90% sRGB coverage and certainly you shouldn"t buy it if it does.

As for native true 10-bit, typically you"ll need to look for an IPS panel, which make up the majority of native 10-bit panels. Some VA panels can do it, but they are rare. Most displays you purchase that claim to be 10-bit, are actually 8-bit+FRC, with only high-end professional-grade monitors offering a native 10-bit experience.

The main differences between TN, IPS and VA for color quality these days comes in coverage of wider gamut, such as DCI-P3, Adobe RGB or Rec. 2020. DCI-P3 and the larger Rec. 2020 are important for HDR videos and gaming, while Adobe RGB is common for work with wide gamut images.

As far as gaming monitors are concerned, which is the majority of monitors we test, it"s uncommon for TN panels to exceed the sRGB color space and produce a wide color gamut. We"ve seen it on occasion, with DCI-P3 coverage topping out around 92% in the best cases, but the majority of TN displays are standard gamut which is fine for SDR content.

The next best panel type for color gamut is VA. Some entry-level VAs will start at only sRGB coverage, but today"s wide gamut VA monitors typically cover between 85 and 90% DCI-P3, or up to around 66% of Rec. 2020. They don"t generally have adequate Adobe RGB coverage (below 85%), making them most suited to a basic wide gamut experience for videos or games. We"ve also yet to test a VA monitor with a really wide color gamut, like 98% DCI-P3, despite the highest end models of today using Quantum Dot enhancement films. Still, VA is decently mid-range for gamut coverage.

If you want the widest color gamut, you"ll need to get an IPS monitor. While basic IPS panels will be limited to sRGB only, the best wide gamut IPS displays offered these days can achieve much higher gamuts than TN or IPS.

We"ve measured up to 97% DCI-P3 and over 99% Adobe RGB in the same panel - usually a high-end model from AU Optronics - which leads to excellent Rec. 2020 coverage above 80%. This tends to make IPS the most, or at times only suitable technology for color critical wide gamut work like video or photo editing, and it"s the tech I"d choose for that task.

Time to talk about speed. Whereas before there was a pretty clear cut distinction between the technologies: TN was the fastest, IPS sat in the middle, and VA was the slowest. In 2021, that is no longer the case, and there"s a lot less separating each technology.

Historically, the highest refresh rate displays on the market were almost all TN models, but that"s not true anymore. Currently there are TN, IPS and VA monitors capable of 240Hz speeds, or sometimes in excess of 240Hz, including at resolutions like 1440p.

The highest refresh rate displays on the market today are capable of 1080p 360Hz speeds, and use an IPS panel from AU Optronics, not a TN. There is lower demand for TN panels than other panel types these days, so a lot of development effort on high refresh models has gone into IPS instead. This makes IPS the highest refresh technology for now, with all three technologies being available at 1440p 240Hz.

Response times have also improved substantially for IPS and VA monitors, especially for high-end panels. There is no longer a clear distinction between TN and the rest of today"s contenders, thanks to big speed gains headed by LG"s Nano IPS and Samsung"s new-gen VA.

The fastest TN panels that we"ve measured using our current, strict test methodology are able to hit the 4ms mark on average with a cumulative deviation of around 400. Cumulative deviation tells us how close a monitor"s response times get to the ideal instant response, and also show the balance between response times and overshoot. The HP Omen X 27 is definitely a fast monitor with its 1440p 240Hz spec. However, the Samsung Odyssey G7 and G9 are actually slightly faster, with response times between 3.4 and 4.0 ms and cumulative deviation below 400.

This puts the best VA monitors of today slightly ahead of the best TN monitors that we"ve tested, which we definitely couldn"t have said a few years ago. With these new panels, Samsung have also fixed the unsightly dark level smearing issue that plagued last-generation VA panels, giving the latest VA panels an overall experience similar to the best LCDs have to offer.

Meanwhile over at the IPS camp, the best IPS panels are slightly slower than VA and TN, but still highly competitive with the best of today. The fastest we"ve seen is a response time average of 4.5ms, with cumulative deviation around 460. That"s less than 20% off the best from other technologies, giving us a pretty small difference in 2021 between the three LCD panel types in a best vs best comparison.

With that said, this discussion of response times only applies to high end monitors. Currently in the mid-range and entry-level markets, the performance differences between TN, IPS and VA are more traditional. TN monitors can still be quite fast, with performance in the 4ms range even with basic 1080p 144Hz panels. Basically if you buy a TN in any market segment, you know it will be fast.

The next step down is IPS in lower price segments, with performance varying a bit depending on the exact model. The reason for this is that mid-range and entry-level IPS monitors tend to use more last-generation panels, which aren"t as fast as the best of today. Still, performance between 6 and 9ms on average is pretty common, and cumulative deviation is still quite competitive, especially in the value-oriented IPS market. Not as fast as TN, but still generally good for motion clarity.

Budget-oriented VA panels are, unfortunately, nowhere near as fast as the best panels of today used in Samsung"s Odyssey G7 and G9 series. It"s much more common to get a 9ms to 13ms average response time here, which puts the best budget VA panels behind an average budget IPS in performance. You"ll also get dark level smearing, which is seen as a dark trail following moving objects, which you don"t get with the other two LCD technologies.

Backlight strobing or black frame insertion is also a popular feature these days for some, particularly those after a high performance gaming monitor for esports. Generally speaking, the performance of backlight strobing is dictated by response time performance, so you can get good results with all three monitor types depending on the implementation, especially with high-end panels.

However these days the most focus tends to go into TN-based esports-oriented monitors when it comes to backlight strobing, so monitors like the BenQ XL2546K can be highly attractive offerings and preferred over the best IPS or VA monitors in this feature. We"ve also seen really good implementations with IPS and VA monitors, but TN is known to be the best.

Summarizing each of the three main LCD technologies is much harder today than in previous years, as there"s been a lot of focus on improving IPS and VA panels. This has led to much better gaming monitors for all, and many more displays to analyze and keep us busy which is always a good thing.

If we had to summarize the LCD ecosystem today... TN panels are a dying breed and their main strengths have been countered in recent years. TN panels are still very fast and great for competitive gaming, but aren"t as much of an outright speed leader anymore, especially at the high end. The main advantage to buying a TN is their affordability and consistency of speed even with entry-level panels, but this comes with weaknesses like viewing angles, contrast ratio and gamut coverage, which makes them unsuitable for a lot of stuff and probably not what you"d want to choose these days.

VA panels are a real mixed bag. At the high end, VAs are very competitive with excellent motion performance, no dark level smearing, decent contrast ratios and good colors. They have to some degree replaced IPS as the middle-ground technology that offers a bit of everything. However in the lower-end of the market, VAs retain the great contrast ratios they are known for, but suffer in motion performance due to the use of last-generation panels and end up quite slow. That"s offset by affordable prices which makes them a decent budget buy in some monitors.

IPS panels have received the most attention and continue to improve each year. IPS monitors are typically the most balanced choice, with strengths in many areas including motion performance, gamut coverage and viewing angles. These strengths tend to apply consistently in all market segments, whether high-end or entry-level, and that can make IPS a great bang for buck option.

Due to the prevalence of flat panels with great uniformity and very wide gamuts, IPS is also the most suitable technology for gaming and content creation on the same display, though contrast ratios are still well behind what VA panels can achieve.

But really there"s no right answer to which monitor technology is best. You might want excellent black levels and great speed, in which case a high-end VA is best for you. Or you might want Adobe RGB coverage, in which case you"ll need to go IPS. There"s no overall winner in the LCD space right now, it"s all about which individual qualities matter most to you.

You should choose between different panel types according to what you’ll mostly be using the monitor for — gaming, color-critical work, or watching movies and other everyday activities.

VA panels have the highest contrast ratio, but it usually comes at a cost of slower response time, so they’re excellent for watching movies, but not suitable for competitive gaming. TN panels are cheap and have fast response times, but have inferior image quality and viewing angles.

IPS panels offer the most consistent colors and a quick pixel response time speed as well as the widest viewing angles, but they don’t have as high contrast ratio as VA panels, and they are usually more expensive.

All newer TN monitors will offer a rapid ~1ms response time (gray to gray pixel transition or ‘GtG’ for short), which eliminates ghosting/trailing behind fast-moving objects.

When paired with a high refresh rate, TN panel gaming monitors provide a buttery-smooth gaming experience at an affordable price, which is why they are usually the first choice of many professional FPS gamers.

TN monitors have the worst color reproduction and narrow viewing angles (170° horizontally, 160° vertically), which causes the image to shift in color, contrast and brightness when it’s looked at skewed angles.

The viewing angles aren’t an issue as long as you’re sitting in front of the monitor, apart from some gamma/saturation shifts, so if you’ve got a limited budget and care more about performance than pretty colors, a TN panel monitor is for you.

IPS panels provide themost accurate and consistent colors as well as wide 178° viewing angles, meaning that you can look at the screen from basically any angle without the image shifting in color and contrast.

Nowadays, most IPS monitors have just as fast pixel response time speed as TN panels (~1ms), though there are still some slower IPS variants with 4 to 5ms.

If you’re watching particularly dark content in a dark room, you will be able to notice light ‘glowing’ around the corners of the screen. This is an expected side effect caused by the excess light passing through the panel.

It’s rather tolerable as it’s only mildly bothersome in certain scenarios i.e., watching dark scenes of a movie/game in a dim-lit room with high brightness setting. In some rare cases, mainly due to poor quality control, IPS glow can be distracting, in which case you should RMA the monitor.

Now, another thing to keep in mind is that IPS panels don’t have as high contrast as VA panels. A standard IPS monitor has a static contrast ratio of around 1,000:1, whereas a VA alternative has around 3,000:1, or even higher.

In 2022, LG Display developed the first IPS Black panel, which increase the static contrast ratio to around 2,000:1! The Dell U2723QE is one of the first monitors released with this technology.

In the past, IPS monitors were more expensive than TN models with the same specs. Nowadays, some IPS monitors are only slightly (if at all) more costly than their TN counterparts.

Keep in mind that there are several variations of IPS panels depending on the manufacturer, and you will also find them named differently. These are the most current versions you should know:

While IPS and TN panels usually have a contrast ratio of around 1,000:1, most VA panels have a contrast ratio between 2,500:1 and 3,000:1, with more expensive models offering even higher contrast.

Samsung’s latest VA panels used in the Odyssey G7 and G9 curved gaming monitors are actually just as fast as some IPS models with 1ms GtG response time!

In fact, there are VA panels that have just as good or better colors than certain IPS monitors, but the colors on those VA displays won’t be as consistent as that of the IPS technology.

In other words, a certain shade of red, for instance, might not look the same at the top of the image and at the center of a VA panel monitor due to gamma shifts.

Thanks to their high contrast and lack of IPS glow, VA panel displays are particularly great for watching movies in a dark room where details in shadows of the picture really stand out, which is why most LED TVs use VA panels, not IPS.

Lastly, although VA panels have specified 178° viewing angles just like IPS, some minor shifts in contrast and brightness are present at certain angles, but nothing extreme.

That’s it! Hopefully, we’ve helped you pick the perfect panel type for you, but there are many other things to consider when buying a new monitor such as screen size, resolution and refresh rate.

All in all, even if you’re a competitive gamer and don’t care much about image quality, a modern IPS monitor is the way to go as you get just as fast response times as that of old TN displays, but a better image quality and viewing angles too.

For color-critical work, we highly recommend IPS monitors, but you can also use VA displays for basic content creation where color accuracy isn’t crucial.

You may be surprised to know that not all LCD panels are created equal. That’s because there’s more than one type of LCD screen. While their differences are subtle, the type of panel technology significantly impacts its image quality and display performance.

In this post, we’ll compare the three types of LCD panel technologies – IPS vs. TN vs. VA – and the pros and cons of each. Knowing the differences is critical to help you find the best type that fits your needs.

The main difference between them is how they arrange and move the liquid crystal display (LCD) molecules in their panels. This, in turn, has a profound effect on image quality, refresh rate, and other performance factors.

A twisted nematic or TN monitor is the oldest and most common type of LCD still used today. It uses a nematic liquid crystal, meaning it has its molecules arranged in parallel, but not on a level plane. These can twist or untwist themselves when a voltage runs through them, hence the name. This twisting effect either allows or blocks light from passing through, turning screen pixels “on” or “off.”

In-panel switching (IPS) panels work similarly to TN monitors, except that the liquid crystal molecules are parallel to the glass panel of the screen. Instead of twisting like in TN monitors, these molecules rotate when a voltage is applied.

Vertical alignment (VA) displays arrange their LCD molecules vertically, perpendicular to the glass panel. When voltage is present, they tilt themselves instead of twisting or rotating.

Being the oldest LCD technology still in use today, TN monitors undoubtedly have their share of benefits, otherwise they wouldn’t have this much longevity! Comparing TN vs. IPS and VA, TN panels are the cheapest and fastest to manufacture. As a result, they are better for the more budget-conscious user. They’re also the most versatile LCD type and have no real-world limits on size, shape, resolution, and refresh rate.

You’ll be hard-pressed to find a TN monitor in a reasonable price range that can display 24-bit (8 bits per channel) color at a wide color gamut, and contrast is limited. The second problem with TN monitors is that because the molecules are not oriented uniformly across the plane, it suffers from a narrow viewing angle. That is, anyone looking at the screen off-axis, such as from a 45-degree angle, will most likely find the image completely un-viewable.

Comparing IPS vs. TN, the former is a drastic improvement over the latter. IPS panels resolve some of the limitations and problems of TN monitors, specifically color accuracy and issues with viewing angles. However, IPS panels suffer from a phenomenon called “IPS glow,” where you can see the display’s backlight clearly if you view it from the side.

Another significant limitation of IPS panels, particularly for gamers, is that they have the lowest refresh rates of any LCD type. And while the color fidelity is fantastic with IPS vs. VA, the latter has superior contrast ratios over the IPS panels.

The biggest strength of VA panels lies in their excellent contrast ratio. Keep in mind that irrespective of the LCD technology used, a backlight is required; this is typically LED. The LCD’s ability to block this light will determine how well it can reproduce bl
