first off – the relevant specs:
GPU: R290 (current drivers)
Monitor: AOC U3277WB
My CAC-1080 does not work with 4k@60hz.
It once worked with 4K@30hz (didn’t go higher than 29hz). Now I’m stuck at FHD.
Driver re-installation (with DDU) didn’t help.
My other CAC-1080 works at 4k@60hz with a Quadro G1000M. It only works at 30hz with the R290.
What can I do?
