This one https://www.amazon.ca/Sceptre-3840x2160-DisplayPort-Speakers-Metallic/dp/B073X6G4DZis pretty decent as long as you don’t mind a few dead pixels out of the box. It uses the same panel from a higher end LG monitor that doesn’t pass QC check for defects in manufacturing.
I really wouldn’t recommend this one. The colours are not very accurate even post calibration due to the TN panel. I know that LG makes a really nice 4K monitor, here is a link: https://www.amazon.ca/LG-27UD58-B-UHD-Monitor-FreeSync/dp/B01IRQAYPE
Ordinarily I would agree with you, but he's already got a pretty nice small form factor ITX system which just needs a CPU upgrade to give it a few more years of life.
Update on the WTB: I may have a lead on the stuff I need, will update thread on Friday.
I’d say in most cases you’re better off sticking to the latest drivers. It’s quite common for new graphics cards to misbehave on early driver releases, so I wouldn’t be too concerned.
If it really bothers you though, it doesn’t hurt to look at an RMA
