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 TN panels are by far the cheapest, but they're also a bit out of date and not as common.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.
