I have a MPB (2020, 16") with Big Sur, and my U3421WE is properly recognised and controls work just fine. Shouldn't be much different for a Mac Mini.

The monitor is a DELL Ultrasharp 34 U3421WE

Hey all, the new 3.0.0 release will have full Apple Silicon support (except for the HDMI port of the M1 mini which disables DDC by hardware for some reason it seems). Please check out that and report if you have any problem!

I'll close this issue meanwhile. Thank you!
