I saw some reviews on Amazon about this stating that quality control was hit or miss, but the panel that I received worked flawlessly out of the box. Very small amount of edge bleed in one corner, nothing that I will ever notice while gaming. Reviews after receiving and one solid day of use. Pros: 144hz is insane when paired with GSYNC. I have a 1070 in my rig, had to tone down to High settings from Epic on Overwatch to get a steady 144FPS @ 1440p, but it is absolutely worth it. If you have a good rig and are still on a 60hz monitor, you are missing out. Literal butter is the only way to describe this. Colors are nice and vibrant. Next to my 24" ASUS run of the mill monitor, its hard to believe that I thought the whites I were seeing were actually white. Calibration wasn't too far off out of the box either. Response time is good, you aren't going to notice 4ms over 1ms in most situations. Overwatch/CS:GO are as fast as they need to be to make sure that you can make the plays you need to make. The build is very nice. The stand is sturdy, and the ergonomic features are great. Added bonus to have the 90deg rotation ability as well, since I play Eve and there are some scenarios where a vertical screen space makes life easier. Cons: To get the 144hz out of this ( I haven't touched the overclock to 165 yet, I need to look in to upgrading my rig to realistically accomplish this) you have to use DisplayPort. This is my first DisplayPort monitor, and any time you switch to a fullscreen game, or the resolution has to change, it isn't very elegant. I've seen odd artifacts, flickering on the monitor and the LED that is on the base, and a bit longer of a wait than what I am used to with HDMI. The payoff is well worth putting up with the small inconveniences though. This may also just be standard with DisplayPort , I am still getting up to speed on what is considered normal for it. The only other complaint that I have so far is how GSYNC and borderless window gaming don't seem to play well. If I click out of a BW game to my second monitor, the refresh rate drops to 60. 75% of the time, it will remain at 60 until I push the "turbo" button on the display to knock it back up to 144hz. I have seen this complaint on forums, and is probably just a software limitation at the point. Still doing some digging as to what the best solution is. But, again, the performance of this screen makes me not care about small stuff like this. Overall, I would definitely recommend this monitor. I have been considering a 144hz monitor for some time now, and couldn't be happier with my purchase.
