Dell 210-AXLH S3221QS 31.5" 4K UHD (3840x2160) 60Hz 8ms VA FreeSync Curved Desktop Monitor

It's ok, but not good. You can get a better experience from many screens, especially nowadays.

This VA panel has severe smearing, which detracts from the otherwise good experience in any game that has motion. Not unexpected at the price point, but buyer beware. It also has persistent flickering on every Mac system I've tried. This seems to be a known issue with no resolution from Dell and no workaround. Just reconnect the screen ~5 times a day and you'll mostly be ok, but sometimes you'll have to live with it which is very distracting when you're trying to work. No flickering on Linux (Pop OS).

Otherwise the resolution, contrast and size are good for the price-point. Nothing to write home about and I'm sure the contrast is better on other panels, but again for the price point it's ok.
