I've found something thing macOS Big Sur broke - the "recovery" after changing display sources. Let me explain...
I have one big 4K monitor, connected to both my Mac (USB-C) and my PC (HDMI). I switch between the two sources on the monitor depending on what I'm doing. Each computer also has its own dedicated monitor (built-in for my Macbook, an old external for my PC).
Prior to macOS Big Sur, if I switched to the PC input on the monitor, all the macOS windows would shift over to the built-in laptop display, and then shift back to their correct window once I switched back. They no longer do that.
The application all stay on the laptop screen and the big screen is empty when I switch the source back on the monitor. I then have to move everything back to the big display.
I guess that's better than the PC behavior where even if you switch the source on the display back to the Mac, Windows still thinks its connected and continues to extend the display (the fix for that is to go to display properties and select "only show on display 2") , but thats a whole other gripe.
Has anyone else experienced this as well? Is there a setting I'm missing? Should I file a bug report?

Add a CommentI am just as frustrated. Brand new Samsung monitor and it is not working on Big Sur 11.4. Black border on each side. Same monitor works great on a Catalina Machine. @apple please fix this.
I have a problem with my second monitor connected to HDMI on Mac Mini M1. Before the update of 11.4, it was working perfectly. I just recently updated the OS and now it takes time for my mac mini to detect the second monitor. Sometimes, I have to remove the HDMI cable and connect it again for the display to work again.
Please @apple fix this problem.
Same issue! After I upgraded my Mac, my hi-res HTMI-connected Samsung monitor streaked and blipped. The windows also jumped around when it would wake up. I had to unplug the Samsung and now it's worthless and collecting dust. I plugged in an old monitor with a VGA cable and the dock and menu still do not work on the second monitor. Luckily, I have not upgraded at home. ...I use three monitors there. I'm a graphic designer. I NEED multiple monitors. Apple, FIX THIS MESS!!!
