Hello Mac mini users 🙂,

since I upgraded my 2018 Mac mini to Big Sur, my HDMI- and Displayport-adapters are unusable. The screens are turning on and off, the picture flickers and there is a lot of noise.
Here is a video:


The adapters are from dell (47kd7,YJ3Y6). Another adapter from Kensington (usb-c to VGA) is perfectly working and the build-in HDMI-port is also working.
This issue exists already in the early betas and I went back to Catalina without any problems.

Does anybody facing the same issue? Is the only solution to buy new adapters?
