Monitor Issues in Big Sur

I have a 2nd monitor connected to my imac 27 inch 2020. It crashes my computer to the point where I cannot work with it unless I disconnect it . I have done further research and found that this is a major issue on Big Sur. The only solution to fix this is to go back to Catalina

External Monitor Issues after installing Big Sur I have an external AOC monitor connected to my 2015 MacBook Pro via USB 3.0. Ever since I installed Big Sur, the monitor no longer functions. It attempts to boot up for 1 sec at start up then goes black. I've seen multiple instances of others having the same issue. When will this be fixed? I have to use dual monitors for my job and I didn't backup prior to the update so I'm worried about using time machine to go back to my pre-Big Sur system until this is fixed.

Run software update to ensure you have the most up-to-date version of Big Sur. Then restart the computer in Safe Mode per the directions in How to use safe mode on your Mac - Apple Support and then restart normally and retest.
