![]() ![]() The best VA panels top out at around 90% coverage of the DCI P3 color space used by most current HDR content. Between VA and IPS panels, the difference isn't as significant however, IPS panels still have a slight edge. We haven't seen any VA monitors with this technology yet, but we wouldn't be surprised if manufacturers started adding wide-angle filters to some high-end monitors.Īlthough 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. These filters significantly improve viewing angles, but come at the expense of contrast. Some manufacturers have started adding wide-angle filters to VA panels used in TVs. Unfortunately, we measure the viewing angles from the center of the screen and rotate the monitor while still measuring in the center, so any advantages from the curve aren't apparent in our test results. Most curved monitors are VA, but there are a handful of TN panels as well. Panel manufacturers came out with curved panels to compensate for this image degradation, as the curved screen reduces the viewing angle to the edge of the screen, meaning that the image appears more uniform if you're sitting up close. They both usually show a decrease in brightness at moderate angles and gamma shift at a small angle, causing the image to appear washed out. Color accuracy generally remains good on VA monitors, but TNs have a slight shift in color accuracy at moderate angles. VA and TN monitors usually perform much worse. IPS is the clear winner here, as the image remains accurate even at a wide angle. Winner: IPS and VA Horizontal Viewing Angles Because of this, almost all high-end monitors currently on the market use VA or IPS panels, so if you're looking for a very bright image, especially for HDR, chances are it'll be either VA or IPS. ![]() TN monitors aren't nearly as popular as they used to be, and the remaining models tend to target high-performance gaming, so there's less of a focus on brightness. ![]() That said, there's a difference between TN and VA/IPS, but it has more to do with market limitations than technological ones. Since the brightness is controlled by a backlight behind the LCD layer, the type of LCD used has essentially no impact on the peak brightness of the display. Most TN monitors we've tested are much worse than this one. The other two are about what we expect from TN and IPS displays, but the ASUS is at the upper end of the range for TNs. We measure contrast at a fixed white level of 100 cd/m², so this means the Samsung's blacks are, on average, 4x darker than the others. Of the three monitors shown here, the Samsung has the best contrast, at nearly 4x the contrast ratio of the other two. If you're not in a dark room, the difference in contrast is hardly noticeable, especially since many monitors have anti-glare coatings that can reduce the effective contrast ratio of the display. In short, if you're often using your computer in a dark room, a VA panel is the way to go, as it's the only LCD panel type that can produce deep blacks in a dark room. Even with local dimming, IPS monitors aren't able to produce blacks as deep as VA panels. Newer monitors even use local dimming to achieve much higher contrast ratios. Most VA panels on monitors have contrast ratios above 2500:1, with some as high as 5000:1 - 6000:1. ![]() IPS panels are slightly better, ranging between 700:1 - 1500:1, but they're still not as good as VA panels. TN panels have the worst contrast by far, typically in the 600:1 - 1200:1 range. The most significant differences between the different LCD panels are in their contrast ratios and viewing angles, but there can be some subtle differences in other aspects of the overall picture quality. Picture QualityĪlthough most monitors today look pretty good, there are some noticeable differences, depending on the type of LCD used. There are high-end and low-end models of each, and the feature sets and performance vary accordingly. We won't be talking much about extra features or design elements, as these vary depending on the overall market context of the monitors you're looking at. In most cases, the difference between each type is pretty minor, but there are a few key areas where one type is consistently better than the others. It can be hard to generalize how each LCD type performs. TN panels are by far the cheapest, but they're also a bit out of date and not as common. When an electric current is applied, the crystals twist and allow light to pass through. TN panels consist of liquid crystals sandwiched between two polarizing filters. TN, or twisted nematic, was the first LCD technology on the market. ![]()
