Well, there were already some of the descriptions here, so I will concentrate on the essentials, in my view. Packaging was ok to carry out the assembly instructions and in the fine without doubt with 2 left hands. Display miniport cable was there and the setup of the monitor input was already set to V1.2. Connect the power cord in, USB cable for communication of calibration software Miniport (graphics card is a Radeon HD 7970) to the monitor, turn on briefly when you start bitching BIOS screen on the resolution, but recognized under Windows everything without problems. Zero pixel errors, prima illumination, incredibly rich colors (AdobeRGB set because I make my photos as well), place no end and so far no flickering or other problems. The monitor can not be heard, the speakers are now not the hit, but completely OK for a sprinkler. If you want more, can indeed dranbaumeln Boller men, executives. Basically 31 inches are just 31 inches and if that's too much, you should look at the 28 inches, but not complain because he has sold himself. The viewing angle stability is good, but if you sit in front of it tightly in doubt, there is minimal color deviations observed. Completely normal and not disturbing for me. Colorful Farbabschattierungen I could not observe, but do not rule out that this can happen when the background music playing a light organ :-). In general I feel the illumination far as exemplary (Test software of Eizo used). Caution: mandatory install the monitor driver and set the profile as the default. Font and icons are easily recognizable, but that is better for everyone to individually. Unfortunately, clear, all programs support UHD not correct and it may even happen that a font is not sharp, but it also seems to read. My conclusion: great monitor, which replaces 28-inch UHD a Samsung and for me is a really huge step, because it simply has a much better viewing angles (although my Samsung has really yet good job for a TN panel), but at the colors he simply no land in sight. Since I'm not a player, I can say to the reaction time, unfortunately, nothing. Otherwise, the buyer should ask before buying one of the strengths and weaknesses of a H-IPS panel. Then there are no false expectations. And that also explains in doubt minimal color shades in dark image, but who in my case nothing to do with the monitor quality, but with the background light. At last a proper on-off switch, integrated power supply and all of that at a great price. And yes, 31 inches are already an announcement, but I find working with it just great. From me there for 5 star.
