Looking good here...box arrived Thursday and looked in perfect condition, but only got around to trying out yesterday.
No sign of any issues so far, screen looks perfect (think some of those with marked surfaces could be because the foam covering the wrong way round maybe ?). Installed fine, DP cable I use needs a bit of finagling due to the limited space in the back but worked fine. Rear plastic cover is a bit flimsy, but who cares once it's in place and out of sight.
Can immediately see the colour improvement, but probably need some adjustment on definition after coming from an IPS, but that's a small thing.
Quick look at God of War, Doom Eternal, Arkham Knight, Alien Isolation etc all looking great. Will have to do some research around the Windows HDR functionality, as while titles like Doom auto switch to HDR, others like God of War need to be manually enabled.
Didn't notice any fan noise but that's probably something that'll be noticeable with extended use, but overall first impressions are very positive. Definitely needs some adjustment on the colour saturation front, but that will come with time.
Downsides......max height adjustment is a shade too low for me on my setup so will have to look at that, and, TBH, like most things in life, I wish it had a few more inches as it looks relatively small in situ due to the slim panel and curvature.
