Dell UltraSharp U2711 review:

Dell UltraSharp U2711

Unreal Tournament 3 and World of Warcraft both looked great running at 2,560x1,440 pixels and showed no signs of ghosting or input lag. Compared with the U2410, the U2711 exhibited deeper and richer color in both games. Its color saturation is among the best we've seen--ranking as good as the HP LP3065's full and deep colors.

We also looked at some high-resolution photos with the U22711 and found that is produced natural and vibrant colors, proving that the two aren't mutually exclusive.

On the Dell U2410, when viewing dark gray in the SRGB and Adobe RGB presets, we noticed apparent static dithering. We didn't see this dithering at all on the U2711 in either RGB mode or in any of the other presets. This should come as a relief to consumers that viewed this flaw as a major sticking point on the U2410.

The optimal viewing angle for a monitor is usually directly in front, about a quarter of the screen's distance down from the top. At this angle, you're viewing the colors and gamma correction as they were intended. Most monitors are made to be viewed only at that angle. Depending on its panel type, monitor picture quality at nonoptimal angles varies. Dell used an H-IPS panel to make the U2711, which usually shows only minimal color shifts with angle changes. On the U2410, we noticed a faint white glow when viewing dark images at off angles and a dark shadow when viewing light images in the same way, about 120 degrees to the left or right and even less from above. The shift isn't as dramatic as with a TN panel, but it was slightly more dramatic than with the 2408WFP; however, its color didn't shift as much as the perceived brightness did.
