tn vs ips lcd panel for sale

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.

When most people go shopping for a gaming monitor, their primary concerns are resolution and refresh rate. Those are certainly important considerations, but if you’ve ever had to put up with dull colors, murky blacks or terrible viewing angles, you’ll understand that panel types are important too.

TN, or Twisted Nematic panels, are the oldest variety of LCD panels, but they’re still quite common even today. They’re cheap to produce, and they have very low input lag, which makes them appealing for gamers. They also support refresh rates of up to 240Hz, another plus for fast-paced environments.

The problem with TN panels is that they have very poor color reproduction. While modern TN panels are far better than earlier models, it’s still relatively rare to find a TN panel with close to full sRGB reproduction. Even if they do have good color reproduction when you’re looking at them straight on, their viewing angles are limited, and they look washed out when viewed from the sides.

If you’re on a budget, enjoy playing competitive shooters or strategy games where reaction times matter, a TN panel could be fine for you. But if you want something that doubles as a media player, the average TN monitor might disappoint.

Fortunately, our GFT27CXB monitor is far from “average.” We engineered our TN panel to do what most TN panels simply cannot: deliver stunningly accurate colors. And with its 99% sRGB gamut, colors are rich and vibrant. And it’s fully customizable, with space to store up to 3 unique user profiles. So you get amazing color. But you also get full HD resolution with lightning-fast speeds up to 240hz refresh rate and 1ms response times.

IPS, or In-Plane Switching, monitors are almost the exact opposite of TN panels. They offer much wider viewing angles than TN panels as well as better black reproduction. The trade-off is that they’re more expensive. They have a history of slower refresh rates, too, although that has been changing lately. Today’s IPS panels can reach max. refresh rates as high as 200-240Hz.

There are some IPS monitors with very good refresh rates and response times, but they’re on the pricier side. You can expect to pay more than $500 for an IPS monitor with a 1ms response time. If you’re looking for a more budget-friendly IPS monitor, then you’ll have to settle for response times of 4ms or slower. IPS panels are also prone to backlight issues. Color reproduction is better than on TN panels, even at extreme angles, but the backlight can sometimes be seen.

Our REAPER series monitor—starting with the RFI25CBA—has been designed to overcome this particular issue. It’s been engineered to reduce the amount of backlight bleed-through on its IPS panel. The monitor also features an MRPT Mode to produce extremely clear moving pictures with excellent color while significantly reducing backlight issues.

VA, or Vertical Alignment, panels are somewhere in between TN and IPS, offering the best of both worlds. This type of panel is common in TVs but is relatively uncommon for gaming monitors. TN panels offer very good contrast ratios, so you can expect vibrant colors and good color reproduction. They also offer good viewing angles, and while brightness may vary depending on the angle you’re looking at the screen from, they’re not susceptible to the backlight issues of IPS panels.

The downside of VA panels is that they have slower response times. As with IPS panels, newer models do have high refresh rates, but the slow response time means you may see ghosting or motion blur in fast-paced, competitive games. Fortunately, all VIOTEK monitors come with AdaptiveSync, which works with AMD® FreeSync® and NVIDIA® G-Sync™ technologies. AdaptiveSync eliminates image distortion (e.g., tearing, stuttering, ghosting and judder) and other glitches that can happen if the monitor’s refresh rate doesn’t match the frame rate of the computer’s GPU. The result is smoother action with clearer images.

There are benefits and downsides to each panel type, and there’s no one correct answer to the question of “which is best.” It depends on your budget, the type of games you enjoy playing, whether you prize response times over other features, and what else you do with the monitor.

If you’re a competitive gamer who wants the absolute best response time on a budget, TN panels will get the job done, but they may disappoint when you’re playing a heavily modded game of Skyrim and want to stop and enjoy the scenery. IPS panels can deliver a similar experience if you’re willing to spend a lot of money. But if you’re like most of us, you’d rather put that extra cash towards a slightly better GPU.

Looking for something with a little more power? The GNV32CBO or GFV24CB are two 1080p monitors. These offer super-fast 165Hz refresh rates for pro-motion with reduced input lag. They’re also VA panels, delivering great color reproduction, AMD FreeSync to reduce image ghosting, and other game-friendly features.

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.

When searching for a liquid crystal display (LCD), consideration of the device’s display technology is essential. Screen technology companies such as Apple and Samsung search for the best possible display panels and panel technology in order to offer their customers the best image quality. In competitive gaming, gaming monitors must be able to provide great image quality but also fast refresh rates so that gamers can play at a fast pace.

Before diving into how exactly liquid crystals affect display features, it is necessary to understand their general role in an LCD monitor. LCD technology is not capable of illuminating itself, so it requires a backlight. The liquid crystals are responsible for transmitting the light from backlight to the computer monitor surface in a manner determined by the signals received. They do so by essentially moving the light differently through the layer’s molecular matrix when the liquid crystals are oriented or aligned in a certain manner, a process which is controlled by the LCD cell’s electrodes and their electric currents.

The methods of alignment, however, can vary between panel types, offering different features and benefits. Two common and popular liquid crystal alignment techniques are twisted nematic (TN) and in-plane switching(IPS).

TN panels offer the cheapest method of crystal alignment. They also are the most common of the alignment methods and have been used for quite a long time in the display industry, including in cathode ray tubes (CRTs) that preceded the LCD.

In TN displays, the electrodes are positioned on either side of the liquid crystal layer. When a current is sent between the back and front electrode, something called an electric field is created that shifts and manipulates the orientation of the molecular matrix.

If no electric field is applied to the specific cell, the crystals experience a 90 degree twist in the alignment. As light from the backlight passes through this twist, the light waves are polarized, allowing them to pass through the polarizer that sits on the surface of the TN monitor.

If an electric field is applied, it can either untwist the TN liquid crystal layer partially or in full, depending on the strength of the field. The structure of TN crystals will typically straighten out when this happens, and some, if not all, light waves will not be polarized properly to pass through to the surface.

Each LCD cell composes a pixel of the display, and in each pixel are subpixels. These subpixels use standard red green blue (sRGB) colors to create a variety of colors to make the pixel display the necessary color to play its role in the overall display. If beneath the subpixel the liquid crystal fully polarizes the light, that subpixel’s specific color would be very bright in the pixel as a whole. But if the light is not polarized at all, then that color will not show up. If partially polarized, only a limited amount of that color is used in the mixture of RGB colors in the final pixel.

A more complex method of alignment is IPS. IPS monitors, unlike the TN, place both electrodes on the same level, behind the liquid crystal layer. When the electric field is applied, this forces the liquid crystal molecules to align themselves parallel to the IPS device layers instead of perpendicularly like the TN molecules.

Opposite of the TN, when the electric field is applied, IPS technology will polarize the light to pass, whereas when the electric field is not applied, the light will not be polarized to pass. Because of the orientation of the crystals, IPS displays require brighter, more powerful backlights in order to produce the correct amount of brightness for the display.

An important consideration is viewing angles. The TN offers only a limited viewing angle, especially limited from vertical angle shifts, and so color reproduction at these angles will likely not look the same as from a straight-on viewing; the TN’s colors may invert at extreme angles. The IPS counters that and allows for greater and better viewing angles that consequently offer better color reproduction at these angles than the TN. There is one issue with extreme viewing angles for IPS devices: IPS glow. This occurs when the backlight shines through the display at very wide angles, but typically is not an issue unless a device is looked at from the side.

In terms of color, as mentioned, TN devices do not have very strong color reproduction compared to other alignment technologies. Without strong color reproduction, color banding can become visible, contrast ratio can suffer, and accurate colors may not be produced. Color gamut, or the range of colors that the device can reproduce and display, is another feature that most TN displays do not excel in. This means that the full sRGB spectrum is not accessible. IPS devices, on the other hand, have good quality black color reproductions, allowing the device to achieve a deeper, richer display, but it is still not the best option if a customer is in search of high contrast (discussed further in a couple more paragraphs).

While TNs may not have the best color quality, they allow for high refresh rates (how often a new image is updated per second), often around 240 Hz. They also have the lowest input lag (receiving of signals from external controllers) at about one millisecond. TN panels often attract gamers because of the need for minimal lag and fast refresh rates in a competitive or time-sensitive setting. In consideration of moving displays like in video game displays, it is also important for fast response times (how fast a pixel can change from one amount of lighting to another). The lower the response time (the higher the response rate), the less motion blur will be shown as the display changes to show motion. TNs also offer these low response times, but it is important to remember that a powerful graphics processing unit, commonly called a GPU, is still needed to push these displays to meet the fastest refresh and response rates.

Standard IPS devices have been known to have slower response time and refresh rates. This can often lead to not just motion blur but ghosting as well, meaning that an image does not refresh fast enough, and so the previous image will remain temporarily burned in the expected new image. In recent years, though, IPS technology has achieved higher refresh rates than in the past through the super-IPS, abbreviated s-IPS.

Oftentimes, refresh rates and frame rate of output devices (such as graphics cards) will not be synchronized, causing screen tearing when two different display images will be shown at once. This problem can be addressed through syncing technologies like Vsynch, Nvidia’s G-Sync, or FreeSync (a royalty-free adaptive synchronization technology developed by AMD).

Another common consideration of customers is the price of each display. TN, though it does not offer as high quality of a display, offers the lowest cost and best moving displays, making it useful if the intended use of the LCD monitor is simple and not too demanding. However, if you intend for something that calls for better color production or viewing angles, the IPS and other methods are viable choices, but at much higher costs. Even though IPS motion displays have reached the speed and rates of TNs, the price for such technology is much more expensive than the TN option.

There are other options besides the TN and IPS. One option is known as vertical alignment (VA) and it allows for the best color accuracy and color gamut. Compared to a typical IPS contrast ratio of 1000:1, VA panels can often have ratios of 3000:1 or even 6000:1. Besides improved contrast ratio, the VA is in between the TN and IPS. To compare the TN vs IPS vs VA, the VA does not have as great a viewing angle as IPS but not as poor as the TN. Its response times are slower than TN but faster than IPS (though at fast refresh rates, the VA displays often suffer from ghosting and motion blur). Due to the contrast ratio benefits, VA technologies are most often desirable for TVs.

And lastly, there is an option quite similar to IPS that is called plane to line switching (PLS). It is only produced by Samsung, who claims the PLS offers better brightness and contrast ratios than the IPS, uses less energy, and is cheaper to manufacture (but because it is only created by Samsung, it is hard to judge pricing). It also has potential in creating flexible displays.

Buying a PC monitor involves a lot of jargon that you have to cut through before making your purchase. You"ve specs like response time and refresh rate to consider, color gamut, contrast ratio, and even the type of panel. When it comes to panel tech, two popular terms you"ll see are TN and IPS.

TN stands for Twisted Nematic and these are the most commonly used panels in PC monitors. Two of the biggest benefits of TN panels are lightning fast response times and a low cost.

Many gaming monitors, particularly those used in a competitive environment, will still be TN-based because the can achieve a 1ms response time that"s currently unreachable for IPS technology.

It also costs less for a TN monitor compared to an IPS. The viewing angles and colors aren"t as good, but if you"re sitting straight on and don"t depend on color accuracy, the cheaper asking price might be a worthy trade-off. You can still go all the way up to 4K resolution, and the latest and greatest panels have a ridiculously fast refresh rate up to 240Hz. IPS monitors aren"t that fast yet.

A quick summary(opens in new tab):IPS is typically more expensive, but produces much higher display quality, with better colors and much better viewing angles.

The viewing angles, in particular, are one of the top reasons you wouldn"t want a TN panel on your phone. IPS displays just generally look better over all. So if you"re anybody working in any sort of visual media or just want your home photos and videos to really pop, then you"ll definitely benefit from the richer colors.

There are high-quality IPS monitors available aimed at gamers, too, but generally speaking the response times are lower on IPS displays than on TN. On an IPS monitor typically you"ll be looking at 4ms and above, though you can still get both high resolution and G-Sync or FreeSync, along with fast refresh rates.

IPS monitors are also usually more expensive than their TN counterparts, but the value proposition is still fairly high when you compare the technical benefits against the increased cost.

It boils down to two main points: Your primary use and your budget. If you"re a gamer or someone on a tight budget, then a TN monitor will likely be your best bet. They"re easily the cheapest and offer both the lowest response time and highest refresh rates.

IPS monitors may well be more expensive but the quality is higher and the colors are much better, as are viewing angles. This is important to consider if you"re ever looking at your monitor anything other than dead straight on. They"re the best all-round choice, especially for creatives, and refresh rates are getting higher.

You come seeking answers to the age old question of TN vs. IPS. Well, then look into my crystal ball. You see how sharp and clear the image is coming through? That"s because it uses an IPS panel. Analogy complete.

But if you want to pick up the best gaming monitor for your PC, you"re going to be confronted with a couple of techie terms: IPS, TN, and VA. Let"s break down what those mean and which one is best for gaming.

Once you get down to it, these terms are actually relatively straightforward, and knowing your IPS from your TN will be of huge benefit when scouring the digital shelves for a bargain.

The best panel for gaming is IPS. There I said it. There"s just one issue with that conclusion: IPS panels can be expensive, especially ones which are made to match their TN and VA counterparts in raw speed. That"s why you"ll find monitors of all panel types on the market and recommended by the critics—if you can"t have everything in one monitor, you need to strike the best balance of strengths and weaknesses.

But first, let"s break down what each term means. It"s important to note that all of the monitor types listed below are LCD panels—which are themselves a type of LED panel.

By those metrics, it"s obvious why TN panels are commonplace across the most popular cheap gaming monitors. They can deliver in the areas that most gamers prefer: refresh rate and response times. It"s also why IPS panels are favoured by artists and creative professionals: they can deliver colour accuracy that"s pivotal to their workloads.

That"s the general idea, anyways. I wish I could end it there, but unfortunately it"s not always quite so cut-and-dried in the monitor world. Where things get tricky is that some panels perform better than others and cross the party lines for a panel technology.

Some TNs don"t look so bad, especially not some of the 24.5-inch ones we"ve seen lately, or the 4K ones. But despite not being famed for high refresh rates, if you want the absolute pinnacle of monitor performance and fidelity then an IPS panel is best suited to deliver. These panels are often found with refresh rates that pale in comparison to, say, a 360Hz TN, but if you"re willing to lay down the cash you can pick up a beautiful IPS rated to 144Hz with a 4ms response time. That will tick all the boxes.

So hopefully you have a better idea of what to look out for when making a monitor purchase. If in doubt, we"ve weighed up all the options and panels to create our best gaming monitor guide—all you have to worry about is how much you"d like to spend.

Choosing a monitor has grown to be a more difficult task for the smart consumer. There are three dominating display panel technologies and a whole list of subsets of technical specifications to work through. The most common argument is between TN and IPS display panels. Both panel types are commonly found in today’s world, whether for office work or at a brick and mortar retail store.

As technology keeps on getting better, the difference between technology keeps getting smaller. However, TN and IPS still have some glaring differences. The most notable differences are the color contrast and viewing angles. TN has almost no viewing angle. Color clarity is lost when the user moves slightly to any side of the monitor other than directly in front of it.

IPS display panels have a much wider viewing angle that has no visual loss except at extreme angles that are unrealistic positions for computer users to be in. When TN and IPS monitors are placed side-by-side, the color contrast and clarity of the IPS panel shine brightly. IPS panels have an 8-bit color panel system that allows for a much wider color range than the 6-bit color panel used in TN technology.

Gamers will usually opt for a TN panel. Designers, artists, producers, and creatives that care about color contrast and image clarity will want to choose IPS displays. These are general recommendations and you may find that either technology will suit your purposes just fine.

Twisted Nematic, or TN, panels are among the most commonly-used monitor panels types around. TN is the monitor panel of choice for gamers. This is not because TN panels are known for visual clarity and increased definition, they aren’t.

It is because TN panels have better response times and refresh rates. This means gamers can take advantage of 144Hz or 240Hz monitors with smoother on-screen motion and less input lag. Responsiveness is critical to competitive gaming.

While it may seem like a millisecond difference in motion, it can be the difference between winning and losing in-game. Other processes that rely on quick refresh rates like stock trading may also benefit from a TN panel monitor.

TN panels are the oldest panel technology available in a monitor. This helps to lower the price of TN monitors on the market versus VA or IPS panels. As TN panels are older technology, they offer a faster refresh rate and response time. This is because the panels are producing less clarity and color vibrancy. There are high-end TN panels that offer wide color ranges, but even then TN panels can’t compare to the image quality of IPS panel colors.

In-Plane Switching (IPS) panels were made to portray better color reproduction and viewing angles. This results in excellent color contrast that doesn’t lose clarity because the viewer is at the wrong angle. IPS monitors are known for their color contrast, brightness, and image clarity.

IPS panel displays can also be purchased at high refresh rates over 240Hz. TN panels still hold a slight advantage over IPS panels in response time, but some high-quality IPS displays are able to match the refresh rate and response time of a good TN panel without sacrificing the color vibrancy found in IPS displays. As time moves forward, IPS may displace TN as the go-to choice for gamers.

IPS panels are also excellent for everyday use. They have excellent image clarity that can suffice for digital graphic design. As IPS describes a wide range of products, there are both gaming-specific IPS monitors as well as sRGB focused IPS displays for designers. As it stands, TN monitors are still more commonly available with 1 ms response times than IPS displays.

IPS displays are commonly used for laptops and 2-in-1 devices. The high brightness, color contrast, and wide viewing angle create a better experience on laptop devices.

PC monitors and laptop screens come in all manner of shapes and sizes, but at their heart nearly all have one thing in common: an LCD panel. But not all LCDs are created equal. Some are better for gaming, some offer better contrast and some produce more accurate-looking colours. So, which is the best LCD type for your needs?

We’ll get to how the technology works below, but what you probably want to know off the bat is which technology is right for you. Here we’ll break down the main characteristics of each type: IPS, VA and TN.

Both IPS and VA have two main advantages over TN panels. The first is that they offer much better viewing angles. In other words, you can view both VA and IPS panels from far shallower angles and still be able to see what’s on-screen without much, or any, colour degradation. This is quite a big deal.

VA panels don’t tend to be quite as good as IPS, and as a result there can be a somewhat noticeable variation in brightness when viewed from different angles. ButIPS suffers from what’s known as ‘IPS glow’. This is where the backlight of the LCD shines through when the display is viewed from a certain angle.

Another advantage of IPS and VA panels is that both tend to present better colour reproduction – again, because they simply have a more controlled and precise ability to manage the light that passes through.

As for other differences, IPS tends to have a faster response time than VA since its crystals don’t have to tip over and then twist as they do with VA (see below). You can get fast-refreshing gaming monitors that use VA, but they offer a poor experience due to the slow pixel response time. IPS is slower than TN, but can be fast enough for responsive gaming.

Meanwhile, VA’s last hurrah is contrast. Since its resting state blocks light, its black level is the lowest of all LCDs, yet it can still produce bright colours when needed. A typical IPS or TN panel will have a contrast of 1000:1 or lower. VA panels can double that. This is the reason VA tends to be the best choice for TVs, where a deep black level is important for enjoying movies.

As for TN, it isn’t all bad news – it has a couple of key advantages. The first is that it’s easier to produce so can be used to make cheaper monitors.

If you’re after a monitor that offers great image quality for day-to-day work and image editing, but aren’t particularly bothered about super-competitive gaming, then go for an IPS screen. They deliver the best all-round experience for work and play, and you can still get gaming IPS monitors that refresh at over 100Hz, making them nearly as good as the best TN gaming screens.

However, if gaming is your be-all and end-all then TN is the way to go. Not only are they the most responsive – with the latest displays having refresh rates of 240Hz – but they also tend to be relatively affordable.

That leaves VA, which is the least suited for fast-paced gaming and isn’t as good as IPS for most day-to-day computing such as reading emails, browsing the web and writing documents. However, great contrast levels means it’s the best for watching video and playing some games. So, if you’re looking for a screen to be part of a a multimedia hub then VA might suit your needs.

In the case of LCDs, a grid of pixels made from liquid crystal is sandwiched between two polarising filters and placed in front of a backlight. As light passes through this assembly, it’s either blocked by the second filter or allowed to pass, depending on the orientation of the molecules in the liquid crystal. Vary the voltage and it varies the orientation of the molecules.

This basic principle is what controls the pixels of any LCD panel. Split each pixel into three and add colour filters for red, green and blue and you have yourself a colour LCD screen.

These fundamentals apply to all the different types of LCD available to buy. However, in order to improve certain characteristics of the displays, different types of LCD have been developed that tweak the way in which the liquid crystal, polarising filters and the electrodes are arranged and controlled.

The original and most basic version of a modern LCD is TN, or twisted nematic. This has the polarisers arranged at ninety degrees to one another, so that – normally – no light passes through them. However, the resting state of the crystal has the molecules arranged in a helix, which twists the polarisation of the light as it passes through, in turn allowing it to pass through the second filter.

When a voltage is applied to the liquid crystal the molecules point directly towards the viewer, so no longer twisting the light, resulting in it being blocked by the second polarising filter. TN works well enough, but famously suffers from poor viewing angles (see above), which is why alternative models were developed.

The most famous of these is IPS, or in-plane switching. Here the polarising filters are in the same orientation so that light is blocked when the crystal is in its resting twisted state, rather than allowed to pass through as it would in TN. Then, when activated, the crystals line up in the same direction as the polarising filters and parallel to their surface: for instance, when switched they’re in-plane.

There are several variations on IPS, such as S-IPS and H-IPS, that use slightly different pixel structures and layouts, and have optimisations for faster response times – most displays that are referred to as IPS are in fact S-IPS panels – but the fundamentals are the same.

Samsung has also developed PLS as an alternative to IPS. It’s basically a reworking of the technology that allows Samsung to manufacture the panels without infringing on existing patents.

The other most common variant is Vertical Alignment (VA). Here the crystals are arranged perpendicular to the polarisers, which are again orientated at right-angles as they are with TN. As such, in its resting state a VA panel blocks light as the light isn’t being twisted. When a voltage is applied the crystals tip to a more horizontal position and twist, allowing light to pass through.

This is how far off-centre you can view the screen without the quality of the image degrading significantly.A TN panel has generally poor viewing angles, if you’re not square-on to your monitor then the image and colours will dull. This isn’t too much of a problem for office work as we almost always have a monitor straight in front of us.IPS panels offer much better viewing angles, so you can have this monitor at an angle to you with almost no change in colour representation at all, but when viewed from some extreme angles blacks may exhibit a glow from the backlight, which can be distracting in darker images.

This is colour accuracy, think if you design a brochure on the screen and you send it to the printers and when you get it back the colours aren’t exactly the ones you specified. This is colour accuracy.Response time, or how quickly the monitor can change the pixels on the screen.IPS panels offer more vibrant and accurate colour representation than TN panels. This is due to their better precision in how the light is passed through the LCD crystals.A TN panel can’t match an IPS for colour accuracy but they do win in refresh rate, although some of the more expensive IPS panels can match a TN. You will see these in Gaming monitors, with a hefty price tag. When does response time matter? Anything with fast moving images (some games, watching sport etc).

The difference between the brightest whites and the darkest blacksTN panels loose out here again to IPS offering higher contrast ratios. Higher contrast we generally associate with better image quality, it’s not entirely accurate but it’s maybe the easiest to tell the difference on.

So which one for an office PC?If the user is doing any design based work where colours on the screen need to be as close to what may be printed as possible, or if the user will have multiple monitors off-centre and doesn’t want the image to degrade, or just wants a vibrant and generally great viewing experience, then an IPS panel in monitor will give you that.Otherwise a TN panel is perfectly acceptable for general office use and is better for your budget.

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
