Hi,
Specs:
Issue: Every x minutes the screen goes black for 2 seconds and then come back working as if nothing had happened. I'm currently running two 4K@60Hz monitor, one over DP, one over HDMI 2.0. The issue only occurs with the HDMI, I sadly cannot use the DP of that monitor as the port is broken.
I'm currently running Big Sur 11.0.1, however it was happening too with Catalina and a different RX 580 (was an ASUS, now I have a Sapphire).
I already tried switching HDMI cable.
-cdfon boot flag doesn't work either.
I tried reducing from 60Hz to 50 Hz, it does seem to have a small impact, it happens less often but still does. Over 30Hz it never happens.
Is there a way to fix this?
Thank you
James
