This is a shocking monitor, it has every bell and whistle. HDR, build in speakers, High resolution, smooth Hertz. Then it does something extra, I was not expecting nor wanting, but won't argue. It can do 4k, some times.
It runs at 143.972Hz says windows, but the setting is 144Hz and it is smooth and crisp.
It has the 0.4 Response time that I expected!
The 27 inch screen pops in the tiny bezel it has.
The build in speakers are poor, but for a gamer most games are done with headphones, so I am not knocking to much for that.
The HDR it has, is the first time I used HDR ever, so I am not sure the point of HDR, when I turn it on the colours get washed out. It might just me user error, I can not say, nor do I wish to use HDR anyway.
It easily displays 2560 by 1440, however it also does something I did not expect. It downscales 5120 by 2880 to 2560 by 1440. Which is an expected thing for most 2k screens as things like the PS4 Pro does not support 2k. But what I was not expected it, when on my PS4 Pro, it according to the screen info is displaying 3840 by 2160.
