So I finally received the monitor and have been playing around with it for some time now. Time to give out some initial impressions of the monitor. I will be comparing the monitor to the previous Asus monitor I had, which was also "reviewed" here
almost two years ago
The first things first. The monitor stand is more sturdy than what I've seen on any of my monitors. It has all the possible adjustments available, like VG278HE had. There isn't much to add to be honest, the monitor is just standing firmly which is good.
As for the image, yeah, being 27" doesn't really strike me as much, but the huge resolution of 2560*1440 is really something else. There's so much room on the desktop now that it is surreal. In games this means lower fps so be prepared. The panel the monitor has seems to be one of the better TN ones, so it does look pretty good. Colors and gamma are okay, also worth mentioning that there isn't pretty much any backlight bleeding, but I can confirm this only later tonight when the sun sets down.
Response time seems ok, input lag feels extremely low. I haven't tested the ULMB mode on the monitor yet, because it doesn't work at 144Hz so I'd be limited to 120Hz when testing that. I did, however, test the G-sync, which seems to give extremely smooth experience in gaming. I don't know if I'd recommend this for QW, but I did test it and it had none of the problems vsync imposes. Also note that you can't really run the game at 144fps with G-sync as it will introduce some input lag. So run the game at lower fps like 140 or even 135.
Well I guess that's the most important parts. Overall I'm pretty satisfied with the monitor.and I will get some more experience with it in the near future, but I don't know if there's anything to add at this point at least.
