I can recommend the Iiyama PROLITE X4071UHSU-B1, a 39.5" dumb screen with a nice panel and the choice between 2160p60@10bit or 2160p75@8bit. I did not get my GPU to spew out the latter though. These two only work over the Displayport, afaik. It is honestly the nicest panel I ran across on a dumb screen. Nice too as a Desktop screen, the screen real estate is worth it if you live in a city, earning city wages on your computer, and can use it productively. Only downside I noticed is the long boot time it seems to show. Combined with the low black level, you need the room somewhat dark to notice if the Backlight turned on. Netflix 4k on it is gorgeous, as long as it's close by.
