RX 570 Doesn't output 4k at 60hz

[hulambre]

Hi everyone,

My RX 570 card does not support my 4k monitor at 60hz. The max resolution it does is 2048x1080 at 24 hz.

I am on Ryzen with B450 motherboard. Using the attached EFI on the EFI partition and nothing else.

Any ideas?

Have you tried something like DisableMonitor.app to unlock extra resolutions?

No I haven’t. The normal resolutions were under system preferences at some point so it should be ok

Update: Attached .plist solves this.
