Mac Mini M1 Screen Flicker
Hey
I have a newly acquired Mac Mini M1, to replace a 2015 MacBook Pro. I used the MacBook primarily as a desktop previously and so the Mini is a good solution as I don't really need portability.
I have the Mini connected to 2 external monitors, both are AOC U2878G6 28" 4K minitors. I have one into the HDMI port and the other into Thunderbolt via a high quality HDMI to Thunderbolt converter.
I'm suffering from screen flicker on the screen that is directly connected to HDMI only. It comes and goes without obvious reason as to why - i've checked the Activity Monitor for example and it's not when the CPU is loaded or anything simple like that. I've also changed the HDMI lead just on case but to no avail.
I see there is other traffic on screen issues although most is about complete flciker such that the screen can't be read where in my case, it's flicker as if the hertz band is out for a moment, like you would get on a TV that's overloaded by a green screen background and can't handle the contrast well.
Using my computer in dark mode, as i have always done since that was launched. I don't know whether it's blacks and dark colours that may be the problem?
Any advice from the community would be welcome.
