Just remember this order.

VA and IPS panels compete with each other. For products of same price, generally speaking, response time and viewing angle of IPS are slightly better, while contrast and uniformity of VA panels are slightly better. it is also very difficult to distinguish between two, because in addition to panel factors, imaging engine and panel IC driver are also key to determining effect.

Real life comparison of TN, IPS and VA between three monitors

What I said above is a textual overview that is not intuitive enough and hard for everyone to remember.

Let's look at PConline website and find 3 monitors with IPS, VA and TN screens to see if actual display effect matchestheoretical result. Let's not talk about performance, let's see what points will affect your experience in everyday use.

Grayscale. Let's talk about grayscale first. How do they affect everyday use? Among these screen types, TN panels are native 6-bit, and IPS and VA panels are native 8-bit, difference between them is difference in number of colors, and TN panel is 2 The sixth power of IPS and V screens is 2.62 million colors, and eighth power of 2 is 16.77 million colors for IPS and V screens. The number of colors differs significantly.

In grayscale image above, we can see transition from white to black because 8-bit panel contains more colors in middle gray area than 6-bit panel, so color transition is more natural in terms of perception, i.e. e. good for watching movies. And when viewing pictures, there will be clear sensations. Although there are many 6-bit panels that use IC driver algorithm to increase displayed color, display effect still has a certain distance from original 8-bit.

View Angle. Another point that affects everyday use is viewing angle of screen. The TN screen also has birth defects due to arrangement of liquid crystals. As mentioned above, when an IPS screen displays black, liquid crystal molecules will twist in horizontal direction, so no matter which direction human eye sees long axis of liquid crystal, and liquid crystal molecules twist in vertical direction into TN screen makes light perpendicular screen, so it only has best viewing effect when human eye looks at screen, and color cast will be obvious when the screen is viewed from an angle.

(TN screen viewing angle is awfully narrow)

In contrast, IPS screens and VA screens are both wide viewing angle screens. Most advertisements can reach a 178 degree viewing angle, which is already close to 180 degrees and can mostly be derived from actual perception. . If you use it alone, low viewing angles on left and right on a TN screen may not have much effect on you, but up and down viewing angles are very poor.

(IPS and VA color rendering is not bad, except for side dimming)

Light leakage and contrast. IPS screens had so many advantages mentioned above that let's talk about its disadvantages. Since IPS screen adopts horizontal arrangement of liquid crystal molecules, it increases viewing angle and reduces light penetration. In order to achieve same display effect as others, it is necessary to increase brightness of LED backlight, increasing brightness of backlight while displaying black will be brighter than on other panels, that is, light leakage phenomenon is more serious, which is very common in IPS screens.

(TN screen, light leakage across whole panel is well controlled, light spill from below should be a build problem)

IPS screen, since IPS screen we tested has been used for a long time, above uneven color blocks may be artificially caused. Because IPS screen doesn't render blacks deep enough, it has also lost its high contrast competitive advantage.

The overall light leakage of VA screen is also well controlled, and overflow on top and bottom sides can also be a build issue.

True test shots: IPS color accuracy and low TN resistance

Judging by sunset at sea level, all three pictures seem slightly oversaturated from point of view of red sunset, and IPS screen is best in terms of color reproduction. Pay attention to four corners of 4 images, here is a display edge uniformity test, you will find that TN screen has most severe vignetting and details are lost. The uniformity of this IPS screen is best, followed by VA.

Judging by this portrait of a young girl, TN screen has revealed a whitening problem. The color of skin and color of wooden door are very pale, and there is still a problem of a dark corner in upper right corner. This once again confirms fact that uniformity of this TN screen is not high. While IPS is still most accurate restoration, VA tends to oversaturate color, and when applied to face, it looks reddish, as if a little drunk after drinking some wine.

According to above two light and color proofs, TN directly restores bike's green color to a similar blue due to a color rendering problem, and image tolerance is low; IPS still maintains a small comparison at first glance. Normal, but this is tonality with best color reproduction; This VA screen maintains a consistent trend towards oversaturated hair color whether it's a motorcycle green or a volcanic magma red, saturation is clearly superior to original image to naked eye.From Starscream test results in following article 100% color gamut sRGB also confirms this result.

Summing up, which one should I buy: TN, IPS or VA?

Everyone tends to choose IPS panels these days. The hard screen has a better viewing angle guarantee, colors will be better, and price is much more expensive. But in fact, we really saw that many VA panels are already inferior in quality. I am gradually catching up with IPS screen. In high-end realm, IPS panel is still unshakable and we don't have to choose a monitor with an IPS panel.

If you don't play games, you don't have high image quality requirements and your budget is relatively limited. If you use monitors for everyday use at home or in office, you only need to buy a regular TN screen monitor that suits your needs.

If you don't play games, you have certain image quality requirements. Then I would advise you to buy IPS or VA panels, both are doable, of course you get what you pay for.

If you mainly play games, you are not very sensitive to image quality. Because esports has high requirements for monitor refresh rate and response speed, I would recommend you buy a TN screen monitor with high refresh rate and extremely fast response.

If you play games from time to time, you have certain image quality requirements. Then please sacrifice responsiveness and high refresh rate, general IPS and VA are acceptable.

If you mainly use it for gaming, you are very sensitive to image quality and then you want a quality experience. IPS has a high refresh rate panel to choose from. Of course, response speed will be sacrificed compared to TN and price will be relatively high. For example, ROG PG279Q also has a refresh rate of up to 165Hz.

If you have high image quality requirements, meet professional requirements. Then one can only say about selected monitor that it is unsuitable for e-sports. One can only say that occasionally you can have fun, because for a stable output of a high-quality picture, you have to sacrifice a high refresh rate and response speed.For time being, only IPS panels can overwhelm other panels in terms of overall quality.

Of course, this is only a general analysis of display panel, and general characteristics of several display panels are analyzed. Of course, there are special situations, and we need a special approach to special situations. For example, I will not talk about ΔE here, because there are not many friends who know value of ΔE and do not know how to choose a monitor. Offers here should be enough for us, ordinary consumers, to choose a monitor.
