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.

In this succinct guide, we"ll provide a brief overview of common initialisms found in the world of TV, PC monitor, and laptop displays. To keep things simple, we"ll focus on how each technology impacts expected image quality. Whether you"re looking for a handy refresher for the next time you"re shopping or a quick, digestible guide to give to inquisitive friends and family, we"ve got you covered.

You"re likely reading this article on a liquid crystal display (LCD). "LCD" refers to any display type that uses liquid crystals, including TN, IPS, and VA (which we"ll get into shortly). Even an old-school calculator or digital watch can use an LCD. But a simple "LCD" designation doesn"t tell you how a screen will perform. You need more information, like the backlight type the panel uses—usually LED, followed by the more expensive Mini LED.

LCDs long ago ousted cathode ray tube (CRT) and plasma displays as the dominant consumer display tech. In the past, it was common to find LCDs with cold cathode fluorescent lamp (CCFL) backlights, but most LCD displays today use LED backlights (more on that below).

TN, IPS, and VA are the three primary types of LCD displays you"ll find in TVs, monitors, and laptops. They all vary in how they use their liquid crystals. Each could warrant its own article, but we"ll keep it simple here by focusing on the differences you can expect to see in real life. Advertisement

It"s easier to reach high refresh rates and low response times with TN displays, although pricier IPS and VA are catching up. It"s worth noting that the upcoming Asus ROG Swift 500 Hz Gaming Monitor, which should be the fastest monitor on the market, purportedly achieves its refresh rate via an "E-TN" panel that claims 60 percent better response times than regular TN. So while you can buy a supremely fast IPS (up to 360 Hz) or VA monitor, TN is still the technology pushing the limits of refresh rates.

VA panels excel in contrast, which is often considered the most important factor in image quality. VA monitors commonly have contrasts of 3,000:1, while a typical IPS comes in at 1,000:1. IPS Black displays, which started coming out this year, claim to double the contrast of typical IPS monitors to up to 2,000:1. We reviewed the IPS Black-equipped Dell UltraSharp U2723QE, and the difference was noticeable.

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.

LCD Monitor Course II, which kicks off this session, will address certain points one must know to choose the LCD monitor best-suited to one"s needs from the various models available. Part 1 will focus on color gamut. While wide color gamuts are the latest trend in LCD monitors, color gamut is a term that lends itself to misunderstanding. Our hope is that this session will help users better understand the color gamut of LCD monitors and better select, use, and adjust the products.

Note: Below is the translation from the Japanese of the ITmedia article "IT Media LCD Monitor Course II, Part 1" published on November 11, 2008. Copyright 2011 ITmedia Inc. All Rights Reserved.

Various standards govern color gamuts. The three standards frequently cited in relation to personal computers are sRGB, Adobe RGB, and NTSC. The color gamut defined by each standard is depicted as a triangle on the xy chromaticity diagram. These triangles show the peak RGB coordinates connected by straight lines. A larger area inside a triangle is regarded to represent a standard capable of displaying more colors. For LCD monitors, this means that a product compatible with a color gamut associated with a larger triangle can reproduce a wider range of colors on screen.

This is a CIE XYZ color system xy chromaticity diagram. The areas enclosed in dotted lines represent the range of colors human beings can see with the naked eye. The ranges corresponding to the sRGB, Adobe RGB, and NTSC standards defining color gamuts appear as triangles connecting their RGB peak coordinates. The color gamut of an LCD monitor"s hardware can be indicated using similar triangles. An LCD monitor is not capable of reproduction (display) of colors outside its color gamut.

The standard color gamut for personal computers is the international sRGB standard prepared in 1998 by the International Electrotechnical Commission (IEC). sRGB has established a firm position as the standard in Windows environments. In most cases, products like LCD monitors, printers, digital cameras, and various applications are configured to reproduce the sRGB color gamut as accurately as possible. By ensuring that the devices and applications used in the input and output of image data are sRGB compatible, we can reduce discrepancies in color between input and output.

Adobe RGB was defined in 1998 by Adobe Systems, maker of the well-known Photoshop series of photo-retouching software products. While not an international standard like sRGB, it has become— backed by the high market share of Adobe"s graphics applications—the de facto standard in professional color imaging environments and in the print and publishing industries. Growing numbers of LCD monitors can reproduce most of the Adobe RGB color gamut.

NTSC, the color-gamut standard for analog television, is a color gamut developed by the National Television Standards Committee of the United States. While the range of colors that can be depicted under the NTSC standard is close to that of Adobe RGB, its R and B values differ slightly. The sRGB color gamut covers about 72% of the NTSC gamut. While monitors capable of reproducing the NTSC color gamut are required in places like video production sites, this is less important for individual users or for applications involving still images. sRGB compatibility and the capacity to reproduce the Adobe RGB color gamut are key points of LCD monitors that handle still images.

In general, the LCD monitors currently available for use with PCs have color gamuts capable of displaying nearly the entire sRGB gamut, thanks to the specifications for their LCD panels (and panel controls). However, given the rising demand mentioned above for reproducing color gamuts broader than sRGB, recent models have expanded the color gamuts of LCD monitors, with Adobe RGB serving as one target. But how is such expansion of LCD monitor color gamuts taking place?

Improvements in backlights account for a significant proportion of the technologies expanding the color gamuts of LCD monitors. There are two major approaches to doing this: one involves expanding the color gamut of cold cathodes, the mainstream backlight technology; the other involves RGB LED backlights.

On the subject of color-gamut expansion using cold cathodes, while strengthening the LCD panel"s color filter is a quick fix, this also lowers screen luminance by decreasing light transmissivity. Increasing the luminance of the cold cathode to counter this effect tends to shorten the life of the device and often results in lighting irregularities. Efforts to date have overcome these drawbacks to a large extent; many LCD monitors feature cold cathodes with wide color gamuts resulting from modification of their phosphors. This generates cost benefits as well, since it makes it possible to expand the color gamut without major changes in the existing structure.

Use of RGB LED backlights has increased relatively recently. These backlights make it possible to achieve higher levels of luminance and purity of color than cold cathodes. Despite certain disadvantages, including lower color stability (i.e., radiant-heat problems) than a cold cathode and difficulty in attaining a uniform white color across the entire screen, since it involves a mixture of RGB LEDs, these weaknesses have been resolved for the most part. RGB LED backlights cost more than cold-cathode backlights and are currently used in a fairly small proportion of LCD monitors. However, based on their efficacy in expanding color gamuts, the number of LCD monitors incorporating the technology will likely increase. This is also true for LCD televisions.

In passing, many LCD monitors that extol wide color gamuts promote the area ratios of specific color gamuts (i.e., triangles on the xy chromaticity diagram). Many of us have probably have seen indications of attributes such as Adobe RGB rates and NTSC rates in product catalogs.

However, these are only area ratios. Very few products include the entire Adobe RGB and NTSC color gamuts. Even if a monitor featured a 120% Adobe RGB ratio, it would remain impossible to determine the extent of the difference in RGB values between the LCD monitor"s color gamut and the Adobe RGB color gamut. Since such statements lend themselves to misinterpretation, it is important to avoid being confused by product specifications.

To eliminate problems involving labeled specifications, some manufacturers use the expression "coverage" in place of "area." Clearly, for example, an LCD monitor labeled as having Adobe RGB coverage of 95% can reproduce 95% of the Adobe RGB color gamut.

From the user"s perspective, coverage is a more user-friendly, easier-to-understand type of labeling than surface ratio. While switching all labeling to coverage presents difficulties, showing in xy chromaticity diagrams the color gamuts of LCD monitors to be used in color management will certainly make it easier for users to form their own judgments.

With regard to the difference between area labeling and coverage labeling as gauges of an LCD monitor"s color gamut, to use Adobe RGB as an example, in many cases, even a monitor with an Adobe RGB ratio of 100% in terms of area will feature coverage of less than 100 percent. Since coverage impacts practical use, one must avoid the mistake of seeing a higher figure as automatically better.

When we check the color gamut of an LCD monitor, it"s also important to remember that a wide color gamut is not necessarily equivalent to high image quality. This point may generate misunderstanding among many people.

Color gamut is one spec used to measure the image quality of an LCD monitor, but color gamut alone does not determine image quality. The quality of the controls used to realize the full capabilities of an LCD panel having a wide color gamut is crucial. In essence, the capacity to generate accurate colors suited to one"s own purposes outweighs a wide color gamut.

When considering an LCD monitor with a wide color gamut, we need to determine if it has a color-gamut conversion function. Such functions control the LCD monitor"s color gamut based on the target color gamut, such as Adobe RGB or sRGB. For example, by selecting sRGB mode from a menu option, we can adjust even an LCD monitor with a wide color gamut and high Adobe RGB coverage so that the colors displayed on screen fall within the sRGB color gamut.

Few current LCD monitors offer color-gamut conversion functions (i.e., feature compatibility with both Adobe RGB and sRGB color gamuts). However, a color-gamut conversion function is essential for applications demanding accurate color generation in the Adobe RGB and sRGB color gamuts, such as photo retouching and Web production.

For purposes requiring accurate color generation, an LCD color monitor lacking any color-gamut conversion function but having a wide color gamut can actually be a disadvantage in some cases. These LCD monitors display each RGB color mapped to the color gamut inherent to the LCD panel in eight bits at full color. As a result, the colors generated are often too vivid for displaying images in the sRGB color gamut (i.e., the sRGB color gamut cannot be reproduced accurately).

Shown here are examples of an sRGB color gamut photograph displayed on an sRGB-compatible LCD monitor (photo at left) and on an LCD monitor with a wide color gamut but incompatible with sRGB and with no color-gamut conversion function (photo at right). While the photograph at right appears vivid, saturation is unnaturally high in parts of the photo. We also see a significant departure from the colors envisioned by the photographer, as well as so-called memory colors.

In more than a few cases, as expanding LCD monitor color gamuts result in the capacity to reproduce a wider range of colors and more opportunities to check colors or adjusting images on monitor screens, problems such as breakdowns in tonal gradations, variations in chromaticity caused by narrow viewing angles, and screen display irregularities, less conspicuous at color gamuts in the sRGB range, have become more pronounced. As mentioned earlier, the mere fact of incorporating an LCD panel with a wide color gamut does not ensure that an LCD monitor offers high image quality. On this subject, let"s take a close look at various technologies for putting a wide color gamut to use.

First we look at technologies to increase gradation. Key here is the internal gamma-correction function for multi-level gradation. This function displays eight-bit input signals on screen in each RGB color from the PC side after first subjecting them to multi-level gradation to 10 or more bits in each RGB color inside the LCD monitor, then assigning these to each RGB eight-bit color deemed optimal. This improves tonal gradations and gaps in hue by improving the gamma curve.

On the subject of the viewing angle of an LCD panel, while larger screen sizes generally make it easier to see differences, particularly with products with wide color gamuts, variations in chromaticity can be an issue. For the most part, chromaticity variation due to viewing angle is determined by the technology of the LCD panel, with superior ones showing no variation in color even when viewed from a moderate angle. Setting aside the various particulars of LCD panel technologies, these generally include in-plane switching (IPS), vertical alignment (VA), and twisted nematic (TN) panels, listed from smaller to larger chromaticity variation. While TN technology has advanced to the point at which viewing angle characteristics are much improved from several years back, a significant gap remains between this technology and VA and IPS technologies. If color performance and chromaticity variation are important, VA or IPS technology remains the better choice.

A uniformity-correction function is a technology for reducing display irregularities. The uniformity referred to here refers to colors and brightness (luminance) on screen. An LCD monitor with superior uniformity has low levels of screen luminance irregularities or color irregularities. High-performance LCD monitors feature systems that measure luminance and chromaticity at each position on screen and correct them internally.

This is a comparison of monitors with and without uniformity correction. An LCD monitor with uniformity correction (photo at left) has more uniform luminance and color on screen than one lacking uniformity correction (photo at right). The two photographs above have been adjusted to equalize levels to emphasize display irregularities. Actual irregularities would be less conspicuous.

To make full use of an LCD monitor with a wide color gamut and to display colors as the user intended, one needs to consider adopting a calibration environment. LCD monitor calibration is a system for measuring colors on screen using a special-purpose calibrator and reflecting the characteristics of the colors in the ICC profile (a file defining device color characteristics) used by the operating system. Going through an ICC profile ensures uniformity between the color information handled by graphics software or other software and the colors generated by the LCD monitor to a high degree of precision.

Software calibration refers to following the instructions of specialized calibration software to adjust parameters such as luminance, contrast, and color temperature (RGB balance) using the LCD monitor"s adjustment menu, approaching the intended color through manual adjustments. Graphics driver colors are manipulated in some cases in place of the LCD monitor"s adjustment menu. Software calibration features low cost and can be used to calibrate any LCD monitor.

In contrast, hardware calibration is clearly more precise than software calibration. It also requires less effort, although it can be used only with compatible LCD monitors and entails certain setup costs. In general, it involves the following steps: calibration software controls the calibrator; matching color characteristics on screen with target color characteristics and directly adjusting the LCD monitor"s luminance, contrast, and gamma-correction table (look-up table) at the hardware level. Another aspect of hardware calibration that cannot be overlooked is its ease of use. All tasks through the preparation of an ICC profile for the results of adjustment and registering this to the OS are done automatically.

The EIZO LCD monitors currently compatible with hardware calibration include models in the ColorEdge series. The FlexScan series uses software calibration. (Note: As of January 2011, FlexScan monitors compatible with EasyPIX ver. 2 offer hardware calibration functionality.)

In the next session, we will examine LCD monitor interfaces and a number of video interfaces for LCD monitors, including the latest generation of interfaces such as HDMI and DisplayPort.

I prefer the Roku interface and pedestal mount of the TCL above, but all people are not me! Many folks (myself included) are in love with the latest mid-tier option from Hisense (8/10, WIRED Recommends). It"s super bright, has similar Mini-LED tech, and features an awesome Google TV interface that makes it perfect for Chrome users and Android owners.

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).

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.

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.

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.

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.

Alternatively, if you’re into gaming and are in the market for TN panel these gaming monitor options may be along the lines of what you’re looking for.

Ascended Extra: Both Riley (of NCIX Netliked fame) and Anthony (one of Linus Media Groups" employees) appear more in front of the camera in 2019 than they did previously. For the former, it was due to being brought onto LMG to host a semi-daily news show TechLinked, while the latter gained popularity after appearing in the background of the more technically complex projects Linus does, normally server, Mac Pro, or Linux related.

Awesome, but Impractical:Linus Tech Tips:Some of Linus" projects are the epitome of this trope, such as attempting to replace a space heater with a gaming PC

Berserk Button: Since he used to paint houses for while, bad paint jobs done on houses is a pretty noticeable one for Linus as evident by how "passionate" he got in ""The Paint Rant""

Canada, Eh?:Linus Media Group is based out of Surrey, British Columbia, a suburb of Vancouver. While it"s downplayed for the most part, since Linus" audience is predominately American, some Canadianisms do slip out, such as Linus pronouncing the letter "Z" as "Zed" when referring to Intel motherboards with a "Zxxx" chipset, or component manufacturer NZXT.

Sometimes, presenters have to explicitly differentiate between US dollars and Canadian monetary unitsnotevariously also referred to as "Canadian rupees", "Canadian rubles," and "Canadian pesos" in certain videos, such as Scrapyard Wars challenges, when addressing GPU and RAM price increases since 2017, and whenever Linus and company buy products to test from a particular brand or store (e.g., Walmart, Amazon, Monoprice, AliExpress, Wish, etc).

Crossover: LTT have done crossovers with other tech YouTubers, such as Bitwit, JayzTwoCents, and iJustine. Gavin Free of The Slow Mo Guys even popped up as a guest cameraman.

Curse Cut Short: In the "Why is EVERYONE Buying This..." mini-series, Linus will say before the Cold Open ends some variation of "why the... is everyone buying this", with the supposed curse word(s) being replaced with a computer"s text-to-speech voice saying "Advertiser Friendly Content".

Cutting the Knot: Happens multiple times in the Tech Support Challenge live stream featuring Jayz Two Cents and Gamers Nexus" Steve. Both are expected to diagnose and fix numerous defects with a pre-prepared PC, including disconnected or poorly-wired components in the case and deliberate severe performance issues caused by changes in the BIOS. Steve gets around half of it by simply dismantling the computer and reassembling it on a test bench from scratch, then resetting the entire BIOS back to factory settings.

Linus: Inside here is an XBOX Series X. Totally normal except for the fact that is has 40 gigabytes of RAM, extra buttons on the front, an OLED display, and it looks absolutely nothing like the XBOX on the shelf at Best Buy.

Anthony: All of the above shouldn"t fail you. But, if you work with tech, you"ll know how often failsafes will fail. "Should" is basically the only thing you can count on.

Greek Chorus: Most TechLinked videos will have one member of LTT as the host, while a second member off-camera interjects with snark, puns, and commentary. (Riley often plays this role if he"s not the host.)

The Klutz:Linus is known to drop expensive tech (most notoriously an Intel Xeon Platinum 8180, a $10,000 cream-of-the-crop workstation CPU), to the point of it becoming a Running Gag and a defining feature of his public and professional persona.

Nostalgia Filter: A mini-series of videos titled "Then vs. Now" deconstructs this trope, as newer technologies offer more convenience in everyday tasks such as listening to music.

Ever since Linus accidentally broke his cameraman Andy"s bed by jumping on it, the Intel Extreme Tech Upgrade videos will never let him forget about the bed.

Linus" screwups attempting to install Steam on Pop!_OS became this for the Linux distro. Many act as if every single attempt to install Steam on it resulted in the desktop getting deleted.

Special Guest:Louis Rossmann, a tech YouTuber known for his Mac repair videos as well as his right to repair advocacy, joins Linus in attempting to reassemble the broken iMac Pro

Strange Minds Think Alike: When Linus and co. visit FreeGeek Vancouver he is digging through some old cables and comes across a bunch of PSU couplers to run two power supplies off the same motherboard, and mentions that Austin could have used them during Scrapyard Wars where he was running a PC with two power supplies. Linus calls over a FG staffer to show them to him, and the staffer says unprompted that Austin could have used them during Scrapyard Wars.

Stunned Silence: When Linus helped Gavin Free build a custom server for Gavin"s own channel, he asked him how long would the server last him until it reached capacity. When he estimated that it would be about 3 months, Linus"s reaction is simply a wide-eyed stare followed by a whispered "Oh my God".

Tranquil Fury: It"s very rare for Linus to actually be angry on-camera when doing a review of a product sent to him, but he does have his moments:In his Intel Core i9 10980XE Review

Linus: "[A higher-up at Intel] then laid down the law and went ahead with this plan to launch first by a matter of hours. Why? So that the launch day reviews, which tend to get referenced by buyers over the entire product lifecycle, Couldn"t. Contain. Direct comparisons, to something you are afraid was going to be better. You are a weasel, and you are a chicken. You seek to misrepresent the strengths of your product to consumers; Weasel. And you seek to duck away from a fight, rather than take the criticism that you know you deserve; Chicken. I hope you get fired, because there are people with more integrity serving lunch in your cafeteria, and maybe they could use a raise. They certainly wouldn"t have handled this any worse than you did."

The "Holy $h!t" series is built on this, with expensive or otherwise incredible technology being the point of the series.Possibly epitomized by the 16k gaming miniseries, wherein Linus and the team put together what would be the internet"s very first successful attempt at 16k resolution gaming. Though most of the hardware involved were provided by partnering sponsors, the total tally came to sixteen top-of-the-line 4k monitors, a custom made desk and monitor mounting rack with an included computer case, which itself was loaded down with four Nvidia Quadro P5000 graphics cards, 128 gigs of ram, and a professional sync card used to keep all the monitors aligned with the proper image without tearing the image.

Vitriolic Best Buds: The phone case company dbrand is this with Linus - while they sponsor videos on the channel frequently, and have collaborated with LTT on products previously, they also take every available opportunity to troll Linus and his viewership in the process. Some of their stunts include offering "SHORTLINUS" as a discount code, registering "notlttstore.com" as a link to their website, advertising a Linus face phone sticker as the "shit tier" sticker, and paying the channel to specifically advertise that a limited-time collab product is no longer available.

What a Piece of Junk: Linus is no stranger to building sleeper PCs that utilize old cases but are packed with high-performance hardware and cooling options. There are three builds nicknamed "Hubert"

Writing Around Trademarks: After NCIX went under, Linus tried to buy assets pertiaining to the NCIX Tech Tips channel. When that failed, he instead hired Riley Murdoch to host a new channel; TechLinked, to get around the deals falling through. Techlinked is a carbon copy of Netlinked Daily, a show that Riley hosted on NCIX Tech Tips.
