Hi there,

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?

Cheers,

Jochen

By the way: If I use the adapter in question for my notebook (with the Quadro GPU) the monitor stays black.

Still have some weeks of warranty, so please help!
