Hi,

running a RX480 in a Omen Accelerator on Fedora 28 (Linux 4.13) looks promising, but it is not quite working.

After switching from Wayland to X.Org and authenticating, my external screen (LG 27MU67-B) displays the (enhanced) desktop. The image looks rather blurry and rendering appears to be very choppy. My monitor tells me "Out of range", indicating that there is some parameter it doesn't like.

I checked the output of xrandr and played around with different resolutions and refresh rates, but to no avail, the message and choppy rendering remain. Any ideas where to go from here?

Thanks.

Try to disable FreeSync on your LG...

I already tried that. Oh well, I guess I stick with my PC for now and try again in a couple of years ;).
