Just got mine today.
Pleased with it so far. Just tried out Killing Floor 2 and, wow, the blacks were way darker than on my old IPS. Corners & unlit areas looked properly black so had to use my flash light...no more blacks that are really dark grey.
Still messing about with the settings, but would recommend it. Text a bit blurrier than on my 27 inch 1440p, but suppose to be expected with less PPI and it's perfectly readable - games look fine though. Thought I might have needed to up the AA, but haven't noticed a sharpness difference and I sit pretty close.
Colours are slightly less 'vibrant' if that's the right expression coming from my IPS, but pretty close to what I had so doesn't bother me and I used an IPS for years. The blacks more than make up for it.
Already won't go back to IPS after a few minutes in KF2
Wish I had this when I was playing Alien Isolation and Resident Evil 7.
Looks pretty cool as well (subtle design - none of that obnoxious 'gamer' crap)...the ambient lighting at the back is a nice touch.
