That's a curious situation. I run my 4k displays over DisplayPort with an RX 580 on Ubuntu 18.04. However, I haven't gone out of my way to obtain drivers from AMD. I'm just using the drivers that ship with the kernel. It might be worth trying a vanilla installation of Ubuntu to see if you can get your set up working.
- wbond 8y agoI did try both the kernel open source drivers and AMD’s pro edition. Most likely you aren’t using Display Port 1.2 MST, which is what the Dell UP3214Q requires for 60hz 4K. My testing was with vanilla Ubuntu 18.04.
