radeon rx580 won't set resolution to 4k












1















I have a 4k monitor (Samsung UE570). I had a GeForce GTX 1060 6Gb card in the system and it worked fine. I've swapped out to a Radeon RX580 and installed the driver (amdgpu), but now I can't set the resolution anything higher than 1280X1024.Ubuntu 16.04. Any suggestions?



TIA
