HDMI white noise

I think I heard through an apple tech that there was an M1 mac issue with HDMI to displays occasionally showing white noise.

I've been having this problem off and on and it's annoying to have to unplug the HDMI and plug it back in.

If anybody else is having this problem please chime in.

If it's not an issue that's prevelant some suggestions on fixing it would be nice.

I'll start by switching out the cable and see if that helps.

Mac mini, macOS 11.6

It happens sometimes to me. I then switch off and on the display. Boring but I can manage.

Powering on/off the display? And here I was unplugging the HDMI from the computer.

I'll try that. Thanks
