s pva lcd panel pricelist

IPS is a general term of LG panel. There are three types, E-IPS, S-IPS and H-IPS. At present, there are basically no S-IPS. Low-end E-IPS and high-end H-IPS. The overall tone is cold and the response speed is fast, hard screen, suitable is to play games.

TFT “, currently widely used in LCD display and mobile phone screens and other display panels. Generally speaking, IPS screen is a screen using IPS technology. Compared with ordinary display screen, IPS screen has clearer and more exquisite dynamic display effect and more outstanding visual effect, therefore, when we choose LCD display or smartphone screen, IPS screen will perform better. Because of this, ordinary IPS screen LCD or smart phones will become a major selling point frequently mentioned by merchants.

Take Dell U2311H LCD as an example, it uses IPS panel with low price. Because Dell U2311H uses reflective coating, the figure is not very clear. However, we can see that similar to the PVA panel, the two halves of each sub-pixel are slightly segmented diagonals, but the difference is that when the screen brightness decreases, the brightness of the refracted light of the whole molecule will decrease, instead of the phenomenon that the middle becomes dark and the brightness of both ends is basically unchanged like PVA panel.

Large visual angle: the viewing angle of IPS screen panel can reach 178 degrees, and the color change degree generated when viewing from the front and different angles becomes the color distortion rate, the obtained value can hardly be distinguished by naked eyes. It means that the effect of viewing the picture from the front or the side is the same.

True color: this is also a comprehensive display of the characteristics of IPS screen color pillow. IPS screen features such as color flip and brightness conversion, allowing you to see high quality images with bright colors and saturated nature no matter from which angle you appreciate them.

Excellent dynamic Image quality: the dynamic high-definition images that can appear on the IPS screen are especially suitable for the reproduction of moving images without residual images and tails. They are used to watch digital high-definition videos and fast moving images, such as competitions, competition game box action movie is a good carrier.

Energy saving and environmental protection: IPS screen technology is more energy saving and environmental protection. And because the liquid crystal molecules are arranged more reasonably, the thickness of the liquid crystal layer is reduced, thus changing the light transmittance of the liquid crystal screen, improving the display effect, and making the liquid crystal display panel thinner, more energy-saving.

Accurate Color: IPS screen technology is favored by professionals to meet the demanding color requirements of professionals in design, printing, aerospace and other industries.

As IPS screen adopts horizontal liquid crystal molecular arrangement, it increases the visual angle while reducing the penetration of light. In order to better display the bright color, it is necessary to increase the luminous degree of backlight, therefore, the phenomenon of light leakage is very common in IPS screens. With the increase of the screen, the problem of large-area edge light leakage has always been criticized by IPS. The method of improving backlight because IPS screen cannot improve penetrability also makes it lose its competitive advantage of high contrast.

We looked at a couple of BenQ LCDs last year and were generally pleased with their features, pricing, and performance. The E2200HD and E2400HD were among the first 21.5" and 24" 1080p computer LCDs to hit the market, and since that time we have seen a veritable deluge of similar displays. Pricing has dropped even further, and if you"re not super concerned with image quality you can basically grab any of the current crop of 21.5" to 24" LCDs and walk away pleased with your purchase. The short summary of what you get is:

The last four items in that list can be summarized with one simple statement: these inexpensive LCDs all use TN panels. There tend to be two types of display users, those that care a lot about image quality and those that really have no idea what image quality means. The latter are not necessarily wrong or uninformed; they just don"t care enough about such things to worry about low-level details and they will usually be happy with any current LCD purchase. These are the type of users that give 5-star reviews to pretty much every LCD on Newegg, as an example. I say good for them and enjoy your inexpensive LCD. In truth, I use TN panels on a regular basis (pretty much every laptop out there uses a TN panel), and while I might notice the difference initially it will fade from conscious thought after a few minutes.

For those that want something better, the choices are far more limited… and far more expensive. Upgrade from a TN panel to a similarly sized PVA or IPS panel and you can usually count on spending 50% to 100% more - or more! - on the purchase. That might be perfectly acceptable if the PVA/IPS panels were all universally better, but that"s not always the case. Color accuracy is almost random it seems, with some IPS panels scoring exceptionally well, PVA panels running the gamut from great to average, and TN panels that likewise fall anywhere from excellent to mediocre. Viewing angles always favor IPS and PVA panels over TN panels, especially in terms of vertical viewing angles. Color gamut is tied to the backlight used in the panel, so you can have poor or great color gamut with any panel technology. Last but not least is image processing speed, and here"s where things get interesting.

To date, the fastest panels in terms of image processing speed (frequently referred to as "input lag") are all IPS or TN panels. These displays are essentially equal and very few people would notice any lag. PVA panels are a different story, unfortunately, with lag ranging from 20 to 50 ms in testing. That means if you purchase a PVA display, you should plan on your display running 1 to 3 frames behind your current input. Most people associate this lag with gaming, and it can certainly affect your performance in fast-paced, competitive games. If what you see is actually three frames behind the current action - and add in networking lag and other types of lag and it could be delayed five or more frames! - you could end up with a competitive handicap. However, it"s not just a problem with gaming. Even in general computer use, a laggy display can make it seem like your mouse is sluggish. Personally, PVA panels with 40+ ms of processing lag feel like the early wireless mice, where there was a small but perceptible delay between moving the mouse and seeing the result on screen. Doing precise image editing, as another example, is an area where faster display processing times are desirable.

The vast majority of LCDs these days are TN panels, and the trend appears to be moving even more in that direction. With a soft economy, many are looking for any way to save money, and even those who really like quality displays may be willing to settle for a less expensive TN panel. S-PVA panels all come from Samsung (they hold the patent on the technology), while IPS displays come from a couple manufacturers. Similar to PVA is a lesser-seen panel type called MVA (A-MVA), and these panels also come from one source: AU Optronics. Some users prefer PVA/MVA images over IPS, for whatever reason, so while my personal preference tends to IPS I was excited to finally have an opportunity to look at an A-MVA panel.

BenQ is one of the retail arms of AU Optronics; they shipped me their FP241VW several months back, and I began testing. Before I could finish with the review, unfortunately, I was informed that the model was being discontinued. However, while that makes the review of the FP241VW less meaningful, AU Optronics still has A-MVA panels and these show up in other displays. That being the case, I felt it would be good to discuss some of the highlights of the A-MVA panels and show limited testing results for the BenQ FP241VW. Why would that even be useful? As you might have guessed there are some interesting performance characteristics to discuss.

As we move into the high-end LCDs, generally speaking we are looking at 24" and larger displays. One offering that you might want to jump on his the Dell 2408WFP, currently on sale for just $482 (though we"re not sure how long that sale will last). We gave this monitor or Silver Editors" Choice award, as it has great features and also delivered some of the best color accuracy results we"ve seen to date. Particularly noteworthy is the fact that it scored 1.74 average Delta E without any calibration -- that"s better than some LCDs do with calibration. The only drawback to the 2408WFP is a significant amount of input lag, although we understand that later revisions have reduced the lag to the point where it might be acceptable. We haven"t been able to personally test the later revisions, so we don"t know for sure how much the situation has improved, but if your primary concern is color quality this is still an excellent LCD.

Other options in this category are interesting, in that you can actually find a few S-IPS or S-MVA. For an S-IPS display, the HP LP2475w runs $585, which is more expensive than a lot of the competition, but our personal preference is still IPS over any of the other technologies. S-MVA panels are few and far between for whatever reason, and at present we are only aware of one LCD in the US that uses an S-MVA panel, the BenQ FP241VW... and it no longer appears to be in production. Still, prices have dropped significantly since the LCD launched, and our own testing indicates that input lag matches the best any of the other LCDs we"ve tested can offer. That means you can get wide viewing angles, good color accuracy, and still not have to sacrifice gaming potential. Finally, there are a few higher quality 22" LCDs that also fall into this category, like the Lenovo L220X, a 22" 1920x1200 LCD with an S-PVA panel. At $485 it costs as much as the Dell 2408WFP, but that"s the price of a high resolution non-TN 22" LCD it seems. Finally, the Planar PX2611W is a 26" S-IPS panel that is very highly regarded by many owners, although it is priced quite a bit higher than the 24" LCDs, coming in at $765.

Last we have the ultra high-end LCDs, with prices that are more than most people will spend for an entire system. Generally speaking, if you"re going to spend this much money we would recommend picking up a 30" LCD, but there are also imaging professionals that will want best in class performance. Most of the 30" LCDs use S-IPS panels and have similar performance characteristics, so it comes down to features. The Dell 3007WFP-HC and HP LP3065 go head-to-head at around $1200 -- the HP costs $50 more at present. The primary difference is that Dell has a single dual-link DVI input along with flash media slots, while HP skips on the flash reader but includes three dual-link DVI inputs. If you never intend on connecting your LCD to more than one computer, either LCD will work fine; if you might want to use a KVM switch down the road, however, know in advance that dual-link KVM switches are extremely expensive. We would give the edge to the HP LP3065, but the margin of victory is extremely small.

If you"re looking for other 30" options, a slightly cheaper alternative that"s worth a look is the DoubleSight DS-305W, which again uses an S-IPS panel but carries a $950 price tag. We haven"t personally tested the display (yet), but $200 is nothing to scoff at compared to the HP LP3065. If you might prefer something other than an S-IPS panel, Samsung offers the 305T with an S-PVA panel for just over $1100. Input lag is reputed to be better than the 24" and 27" S-PVA panels, but we"re not sure it"s at the level of the 30" S-IPS panels. Finally, we should note that the newer Dell 3008WFP includes a bevy of input options, but apparently also suffers from severe input lag, making the $2000 price tag much more than we are willing to pay.

The final two options in the dream LCD category target imaging professionals, and both come from NEC. The 26" LCD2690WUXi uses an H-IPS panel and is priced at $1050, but among users that demand accurate color it has a very good reputation. The other option is another 30" S-IPS panel, the LCD3090WQXi that retails for $2000. If your livelihood depends on accurate colors in print media, the price premium over competing 30" options may not matter. Most users looking to pick up a 30" LCD will probably be more than happy with one of the cheaper options, however.

The 55" NEC UN551S utilizes S-IPS panel technology to provide a superior signage solution for building video walls. With excellent off-angle viewing and far less color shift than traditional video wall panels, this display is ideal for broadcast, retail and command and control applications. On top of that, these displays are designed for the rigors of 24/7 operation with advanced heat management capabilities in which internal temperature sensors automatically activate fan-based cooling if excess heat builds up within the unit. Other advanced technologies of this model include direct LED backlighting with localized dimming for improved brightness uniformity and higher dynamic contrast ratio. These displays are also capable of daisy-chaining UHD (3840 x 2160) resolution so that the entire video wall can be 4x that of FHD regardless of the size of the wall. With these features, an even smaller area between neighboring displays and commercial brightness of 700 nits, this display clearly showcases NEC"s vast experience in the video wall market.

Industrial-strength, premium-grade panel with additional thermal protection, internal temperature sensors with self-diagnostics and fan-based technology, allows for 24/7 operation

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.

Now while that seems to be a pretty good iteration of the VA panel tech should I feel good about getting this sort of thing for gaming or will spending a little more and getting an IPS panel really blow me away since I have already committed to spending way more than your run of the mill monitor out of Best Buy.

I don"t want a TN so I have been trying to get myself a monitor for a few years now and the more I think about it the more complicated it gets. If only I knew nothing about any of this and could just go get whatever costs me $150 at a store.

If you’ve ever begun searching for a new computer screen, chances are you’ve probably come across the term IPS. It’s at this point that you may be asking yourself, what is an IPS monitor? And how do I know if an IPS monitor is right for me?

So, why is this important? A monitor’s panel technology is important because it affects what the monitor can do and for which uses it is best suited. Each of the monitor panel types listed above offer their own distinctive benefits and drawbacks.

Choosing which type of monitor panel type to buy will depend largely on your intended usage and personal preference. After all, gamers, graphic designers, and office workers all have different requirements. Specific types of displays are best suited for different usage scenarios.

The reason for this is because none of the different monitor panel types as they are today can be classified as “outstanding” for all of the attributes mentioned above.

Below we’ll take a look at how IPS, TN, and VA monitors affect screen performance and do some handy summaries of strengths, weaknesses, and best-case uses for each type of panel technology.

IPS monitors or “In-Plane Switching” monitors, leverage liquid crystals aligned in parallel to produce rich colors. IPS panels are defined by the shifting patterns of their liquid crystals. These monitors were designed to overcome the limitations of TN panels. The liquid crystal’s ability to shift horizontally creates better viewing angles.

IPS monitors continue to be the display technology of choice for users that want color accuracy and consistency. IPS monitors are really great when it comes to color performance and super-wide viewing angles. The expansive viewing angles provided by IPS monitors help to deliver outstanding color when being viewed from different angles. One major differentiator between IPS monitors and TN monitors is that colors on an IPS monitor won’t shift when being viewed at an angle as drastically as they do on a TN monitor.

IPS monitor variations include S-IPS, H-IPS, e-IPS and P-IPS, and PLS (Plane-to-Line Switching), the latter being the latest iteration. Since these variations are all quite similar, they are all collectively referred to as “IPS-type” panels. They all claim to deliver the major benefits associated with IPS monitors – great color and ultra-wide viewing angles.

When it comes to color accuracy, IPS monitors surpass the performance of TN and VA monitors with ease. While latest-gen VA technologies offer comparative performance specs, pro users still claim that IPS monitors reign supreme in this regard.

Another important characteristic of IPS monitors is that they are able to support professional color space technologies, such as Adobe RGB. This is due to the fact that IPS monitors are able to offer more displayable colors, which help improve color accuracy.

In the past, response time and contrast were the initial weakness of IPS technology. Nowadays, however, IPS monitor response times have advanced to the point where they are even capable of satisfying gamers, thus resulting in a rising popularity in IPS monitors for gaming.

With regard to gaming, some criticisms IPS monitors include more visible motion blur coming as a result of slower response times, however the impact of motion blur will vary from user to user. In fact, mixed opinions about the “drawbacks” of IPS monitor for gaming can be found all across the web. Take this excerpt from one gaming technology writer for example: “As for pixel response, opinions vary. I personally think IPS panels are quick enough for almost all gaming. If your gaming life is absolutely and exclusively about hair-trigger shooters, OK, you’ll want the fastest response, lowest latency LCD monitor. And that means TN. For the rest of us, and certainly for those who place even a modicum of importance on the visual spectacle of games, I reckon IPS is clearly the best panel technology.” Read the full article here.

IPS monitors deliver ultra-wide 178-degree vertical and horizontal viewing angles. Graphic designers, CAD engineers, pro photographers, and video editors will benefit from using an IPS monitor. Many value the color benefits of IPS monitors and tech advances have improved IPS panel speed, contrast, and resolution. IPS monitors are more attractive than ever for general desktop work as well as many types of gaming. They’re even versatile enough to be used in different monitor styles, so if you’ve ever compared an ultrawide vs. dual monitor setup or considered the benefits of curved vs. flat monitors, chances are you’ve already come into contact with an IPS panel.

TN monitors, or “Twisted Nematic” monitors, are the oldest LCD panel types around. TN panels cost less than their IPS and VA counterparts and are a popular mainstream display technology for desktop and laptop displays.

Despite their lower perceived value, TN-based displays are the panel type preferred by competitive gamers. The reason for this is because TN panels can achieve a rapid response time and the fastest refresh rates on the market (like this 240Hz eSports monitor). To this effect, TN monitors are able to reduce blurring and screen tearing in fast-paced games when compared to an IPS or VA panel.

On the flip side, however, TN panel technology tends to be ill-suited for applications that benefit from wider viewing angles, higher contrast ratios, and better color accuracy. That being said, LED technology has helped shift the perspective and today’s LED-backlit TN models offer higher brightness along with better blacks and higher contrast ratios.

The greatest constraint of TN panel technology, however, is a narrower viewing angle as TN monitors experience more color shifting than other types of panels when being viewed at an angle.

Today’s maximum possible viewing angles are 178 degrees both horizontally and vertically (178º/178º), yet TN panels are limited to viewing angles of approximately 170 degrees horizontal and 160 degrees vertical (170º /160º).

In fact, TN monitor can sometimes be easily identified by the color distortion and contrast shifting that’s visible at the edges of the screen. As screen sizes increase, this issue becomes even more apparent as reduced color performance can even begin to be seen when viewing the screen from a dead-center position.

For general-purpose use, these shifts in color and contrast are often irrelevant and fade from conscious perception. However, this color variability makes TN monitors a poor choice for color-critical work like graphic design and photo editing. Graphic designers and other color-conscious users should also avoid TN displays due to their more limited range of color display compared to the other technologies.

TN monitors are the least expensive panel technology, making them ideal for cost-conscious businesses and consumers. In addition, TN monitors enjoy unmatched popularity with competitive gamers and other users who seek rapid graphics display.

Vertical alignment (VA) panel technology was developed to improve upon the drawbacks of TN. Current VA-based monitors offer muchhigher contrast, better color reproduction, and wider viewing angles than TN panels. Variations you may see include P-MVA, S-MVA, and AMVA (Advanced MVA).

These high-end VA-type monitors rival IPS monitors as the best panel technology for professional-level color-critical applications. One of the standout features of VA technology is that it is particularly good at blocking light from the backlight when it’s not needed. This enables VA panels to display deeper blacks and static contrast ratios of up to several times higher than the other LCD technologies. The benefit of this is that VA monitors with high contrast ratios can deliver intense blacks and richer colors.

Contrast ratio is the measured difference between the darkest blacks and the brightest whites a monitor can produce. This measurement provides information about the amount of grayscale detail a monitor will deliver. The higher the contrast ratio, the more visible detail.

These monitors also provide more visible details in shadows and highlights, making them ideal for enjoying videos and movies. They’re also a good fit for games focused on rich imagery (RPG games for example) rather than rapid speed (such as FPS games).

MVA and other recent VA technologies offer the highest static contrast ratios of any panel technology. This allows for an outstanding visual experience for movie enthusiasts and other users seeking depth of detail. Higher-end, feature-rich MVA displays offer the consistent, authentic color representation needed by graphic designers and other pro users.

There is another type of panel technology that differs from the monitor types discussed above and that is OLED or “Organic Light Emitting Diode” technology. OLEDs differ from LCDs because they use positively/negatively charged ions to light up every pixel individually, while LCDs use a backlight, which can create an unwanted glow. OLEDs avoid screen glow (and create darker blacks) by not using a backlight. One of the drawbacks of OLED technology is that it is usually pricier than any of the other types of technology explained.

When it comes to choosing the right LCD panel technology, there is no single right answer. Each of the three primary technologies offers distinct strengths and weaknesses. Looking at different features and specs helps you identify which monitor best fits your needs.

With the lowest cost and fastest response times, TN monitors are great for general use and gaming. VA monitor offers a step up for general use. Maxed-out viewing angles and high contrast ratios make VA monitors great for watching movies and image-intensive gaming.

IPS monitors offer the greatest range of color-related features and remain the gold standard for photo editing and color-critical pro uses. Greater availability and lower prices make IPS monitors a great fit for anyone who values outstanding image quality.

LCD or “Liquid Crystal Display” is a type of monitor panel that embraces thin layers of liquid crystals sandwiched between two layers of filters and electrodes.

While CRT monitors used to fire electrons against glass surfaces, LCD monitors operate using backlights and liquid crystals. The LCD panel is a flat sheet of material that contains layers of filters, glass, electrodes, liquid crystals, and a backlight. Polarized light (meaning only half of it shines through) is directed towards a rectangular grid of liquid crystals and beamed through.

Liquid Crystals (LCs) are used because of their unique ability to maintain a parallel shape. Acting as both a solid and liquid, LCs are able to react quickly to changes in light patterns. The optical properties of LCs are activated by electric current, which is used to switch liquid crystals between phases. In turn, each pixel generates an RGB (red, green, blue) color based on the phase it’s in.

Note: When searching for monitors you can be sure to come across the term “LED Panel” at some point or another. An LED panel is an LCD screen with an LED – (Light Emitting Diode) – backlight. LEDs provide a brighter light source while using much less energy. They also have the ability to produce white color, in addition to traditional RGB color, and are the panel type used in HDR monitors.

Early LCD panels used passive-matrix technology and were criticized for blurry imagery. The reason for this is because quick image changes require liquid crystals to change phase quickly and passive matrix technology was limited in terms of how quickly liquid crystals could change phase.

As a result, active-matrix technology was invented and transistors (TFTs) began being used to help liquid crystals retain their charge and change phase more quickly.

Thanks to active-matrix technology, LCD monitor panels were able to change images very quickly and the technology began being used by newer LCD panels.

Ultimately, budget and feature preferences will determine the best fit for each user. Among the available monitors of each panel type there will also be a range of price points and feature sets. Additionally, overall quality may vary among manufacturers due to factors related to a display’s components, manufacturing, and design.

Because OLED TVs are newer and generally more expensive, the average buyer is looking at LED/LCD TVs right now. And although there are several features and specifications to consider while shopping—the brand name, HDR compatibility, and refresh rate, just to name a few—there’s one important hardware spec that isn’t widely advertised: LCD panel type.

LED/LCD TVs are so called because of the two things that make up their displays: an LED (Light Emitting Diode) backlight and an LCD (Liquid Crystal Display) panel for that backlight to shine through. LED backlights vary between a variety of implementations, but modern LCDs generally come in one of two panel technologies: IPS (In-Plane Switching) and VA (Vertical Alignment).

Unlike other hardware specifications (which are usually listed on the side of a TV box or on the manufacturer’s website), information about a TV’s LCD panel type is a bit more inside baseball. But panel type has a far greater impact on a TV’s performance than you might expect—it affects contrast, color, and viewing angle as well.

Individual pixels in an LCD display are made up of liquid crystals activated by voltage. How the display arranges its crystals is part of what sets IPS panels apart from VA panels.

IPS (In-Plane Switching) panels are a common display type for both the best computer monitors and TVs. Without getting too far down the rabbit hole, let’s talk a little about how IPS panels distinguish themselves from other types.

Every non-OLED TV on the market today is an LCD TV powered by LED lighting. Individual pixels in an LCD display are made up of liquid crystals activated by voltage—this is what produces color. An IPS panel aligns its crystals horizontally, parallel to the glass substrate.

IPS technology was developed in part to improve the color and wide viewing angle performance of a display. There"s also a range of variations under the IPS umbrella, including ADS, S-IPS, H-IPS, e-IPS, P-IPS, and PLS (Plane-to-Line Switching). But, while they all differ marginally from one another in operation, their core functionality (as compared to VA panels) is the same.

VA (Vertical Alignment) panels represent another common display type, used for both computer monitors and TVs, but especially for the latter where they greatly outnumber their IPS counterparts. Most LED/LCD TVs you"ll find on the market use a VA panel. While IPS panels align their liquid crystals horizontally, VA panels align them—you guessed it—vertically. They run perpendicular to the glass substrate rather than parallel to it. When met with voltage, the crystals tilt, letting light through and producing color.

This positioning changes how the liquid crystals behave. Without any voltage, the liquid crystals in a VA panel do not tilt, which is a better outcome if your goal is to block light and create image depth. Like with IPS, VA panels also come in a few varieties: PVA, S-PVA, and MVA, though again, their core functionality (as compared to IPS panels) is the same.

TN (Twisted Nematic) is an older LCD display type. They"re still relatively common display types for computer monitors—thanks to their lightning fast response times and excellent handling of motion blur. TN panels aren"t typically used in TV production anymore, though.

The cornerstone of picture quality, contrast ratio refers to the range between a display’s darkest black levels and brightest highlights. Because VA-style panels excel at producing deep, dark black levels, this is arguably their biggest strength. VA panels almost always feature deeper black levels than their IPS counterparts, and this goes a long way in creating a detail-rich picture. An IPS panel can mitigate this by serving up an exceptionally bright image to offset relatively shallow black levels.

A TV’s total viewing angle describes how much a viewer can move away from an ideal, head-on viewing position before the contrast and color of the picture begins to deteriorate. Due to the positioning of their liquid crystals, IPS panels excel in this department; they typically offer significantly more viewing flexibility than TVs with VA-style panels. In other words, IPS panels are more reliable for group viewings (or any situation where a viewer might need to sit at an off-angle).

While impressive color production is possible on both display types, IPS panels tend to offer wider colors, given the nature of their hardware. While a wider range of colors tends to spell better color accuracy, the advent of additional TV technologies like quantum-dot color have evened the playing field considerably. In other words, you’re far more likely to notice the benefits of an IPS TV’s wider viewing angle than you are to notice its tendency for wider color.

Here’s the final takeaway: IPS panels are significantly better than VA panels when it comes to viewing angle and somewhat better than VA panels when it comes to color. VA panels, however, almost always offer deeper black levels and better overall contrast. And because they block light better, TVs and monitors using VA panels tend to have better backlight uniformity regardless of LED backlight type.

Unfortunately, not only is it rare to find a TV’s panel type listed on a manufacturer’s website, but it’s increasingly rare for a brand to reveal a TV’s panel type at all—even when we contact brands directly for information. The reason for this caginess has everything to do with marketing; it’s better to keep shoppers focused on the bells, whistles, and impressive performance specs of a TV rather than its potential shortcomings.

To add to the confusion, it’s common for different sizes of the same TV series to mix and match display types; you might find that the 55-inch version of a TV features a VA-style display while the 75-inch model uses IPS.

Fortunately, it’s relatively easy to determine panel type if you have the proper equipment and you know what to look for. Certain test results and viewing characteristics act as tell-tale signs. This is why my colleagues and I make a point of discussing panel type in just about every TV review we publish, and why you should make a point of reading reviews before making a purchase.

Panel type is not the end-all-be-all for LED/LCD TVs. Many other factors, most of them related to the style and intensity of the LED backlight, can have a major impact on factors like contrast, viewing angle, and color intensity. Ultimately, you need to see a TV in person (and ideally in the space it’s going to live in) to get the best idea of how well it creates an image. But by knowing the core differences of IPS vs VA LCD panels, you can at least make some good guesses before you buy.

Unlike the best gaming monitors, IPS and VA TV panels are on an even playing field. TVs with both technologies are capable of high refresh rates of 120Hz, or occasionally 240Hz (although it usually comes at a premium).

If you focus on single-player gaming, or your multiplayer gaming happens online, the excellent contrast of VA is the way to go. The most gaming benefits you’ll see will come from extra features like Variable Refresh Rate (VRR), Auto Low Latency Mode (ALLM), or cloud game capabilities.

If you’re buying a large screen and intend to host movie nights with friends and family, a TV with an IPS-style panel is far more accommodating thanks to its superior viewing angle. Just be aware that certain content—particularly dark content—won’t pop as much on account of the panel’s shallower black levels.

On the other hand, if you want the best possible picture overall, we recommend investing in a TV with a VA-style panel. They’re not always ideal candidates for group viewings, but the vast majority of the best non-OLED TVs you can buy feature this display type.
