Display not recognized after Big Sur update
 

hello,
I am just joining the chorus of users who cannot get their display to works after the Big Sur update to 11.4. I have uploaded my log files and emailed them to the tech team as instructed. I hope this leads to a fix soon.

Not detecting monitor
 

having the same issues as the other guys here is my display info zip.

just got my brand new adaptor for second monitor.. then found out this problem.... instantly wasted..

M1 with 2 different Dell monitors -- 1 of them stuck at 1920x1080
 

Sending the DisplayLink output zip file. Help! :)

My Mac M1 has:
1) Dell U3219Q <-- this one shows the 3840x2160 high resolution that I expect.
2) Dell P2715Q <-- this one shows only 1920x1080 for "More Space" where the text is too big!

I have a new Kensington SD4780P docking station.

Also, I could have sworn that when I first connected the 2nd Dell monitor that it looked right, then after a minute or two the displays went black for several seconds, and afterwards the 2nd Dell monitor was stuck at 1920x1080.
