Good ... but not perfect (from the perspective of Gamers ...)

I got myself this monitor because I wanted to play R9 290X and I7 4790K with more than just Full HD with my 2 AMD Athlon ...
Hab connect the monitor with the supplied cable DP and made a few settings:

Brightness: 80
Contrast: 75
Sharpness: 64
Bright: Users
Angle: from
Response Time: Faster
Gamma: mod 3
Color: all 50

in the beginning everything looked really good. 4k video and also the desktop just perfect ... Full HD videos are displayed very well and look just great from.

Now for gaming. At the beginning of each game, of course, everything first on maximum details and then put down possibly.
Battlefield 4 and 3 strain simply only great if you know how you have set it.
I use the 4K resolution and Ultra settings without antialiasing, since it is more important at this resolution no jagged edges)

The monitor must in these games 60FPS have ... because without jerky and flickers and the images lead to.
V-Sync is on but all below 60 FPS, jerky at least at BF 4 and 3. FIG.
When you come to stätige 60, it just looks perfect and one sees no individual pixels more :)

In Crysis 3, one should put everything on high and turn off anti-aliasing to get to the said frames.

All games I've tested just as playable (60 FPS) eg TombRaider or Thief

Calling all gamers out there, I would wait for the variant with fairy-Sync from AMD or Nvidia G-Sync for users ...
The there is the first quarter of 2015 to buy and to run much better and synchronize the images better.

Those who can not wait and now wants to strike, must have the necessary hardware power to liquid to games.

In a pinch, you can still change to 2560 * 1440, and even that looks wonderful, and because at least here you should achieve 60 FPS, even with a graphics card.

So buy or not buy? Depending decides ^^
