Very happy with them as replacements for my trusty Hazro 27" IPS HZ27WC's.
I personally feel that this screen size/resolution is definitely the sweet spot for productivity. I was a little hesitant of them being too large, however so far, I don't feel so. They are a lot more easier on the eye than the 27"s.
Any larger they would be a issue. I was contemplating 4k, however I think I'd just end up scaling things up too much to see text etc comfortably. I'm now able to sit at my desk with a better posture and not lean in as before.
They will need some tweaking out of the box to get the colours correct and a bit more vibrant.
I notice no particular blue tint. Viewing angles are fine, 75hz no issue on nvidia. No obvious uniformity or back-lighting issues, no bad pixels.
So far delighted.
I can't comment for gaming, However if your on the fence, grab one whilst they are still available, for the price - difficult to beat.
