Monterey 12.3 update Made Secondary Display unusable

So auto updated this morning only to find out I can't full screen one of my displays or the other one would be blank and become useless. Apple just releasing bugs filled update now? what a joke man.

just found a way to fix it.


I had to go to System Preferences > Mission Control and make sure you check the option that says "Displays have separate Spaces".


It will require you to logout for the changes to be applied.

Hey thanks for the reply, I actually found the exact same solution a while back, Idk why the operating system decided to uncheck everything after the update, but either way it was quite a problematic thing for a couple days because it made having external monitor absolutely pointless when one screen is blank due to the "Displays have separate spaces" is unchecked.
