Pros: The picture quality on this monitor is incredible. 4K at 27" looks very crisp and detailed and the contrast is very good beating out any other LCD I've owned. Colors are also vibrant and the out of the box calibration looked good. G-Sync works as it should giving the smoothest possible experience at any frame rates and the max refresh rate of 144Hz makes the gaming experience even better provided you have the hardware to reach frame rates that high. HDR on this display blew me away when I first used it with vibrant colors and a very high peak brightness. Makes me wish more games on PC supported HDR. You might be wondering why I've given this monitor such a low score after speaking so highly of it. More will be explained in the "Cons" section.

Cons: After about a week of use I noticed a stuck pixel in the lower left part of the screen that was stuck on red. Even with the high pixel density of this screen it was still very noticeable even if I moved further back from the monitor. I tried for a few nights running programs to fix the stuck pixel but nothing worked. I was on the fence about sending it back until I noticed a dead pixel around the same area of the stuck pixel. After seeing this I set up an RMA with NewEgg for a replacement. This monitor costed way too much for me to put up with pixel defects like this and I don't think anyone should should who buys this monitor. If I get a replacement that I am satisfied with I will update this review and the score but until that happens it will remain at one egg.

Overall Review: It's worth mentioning that 4K takes a lot of GPU horsepower to run games at with ultra settings. My 1080 was passable with the games I tried bringing in levels of performance that was just playable. I then bought a used 1080Ti for cheap and sold my 1080 and the 1080Ti does much better of course but to get frame rates closer to 120 or 144 you'll need much more GPU power.
