My Macbook Pro M1 suddenly isn't showing the correct resolutions anymore
I've solved the issue. Seems like SwitchResX for some reason messed up with the system resolutions. I've updated to the latest beta version of SwitchResX (4.11.1a4), opened SwitchResX Preferences and then, on the menu at the top of the OSX screen, clicked &quot;Display &gt; Restory factory settings&quot;. Then after a reboot it was back to normal. Geez

&quot;Restore factory settings&quot; is greyed out now, but it wasn't before. Clicking on it and rebooting solved the issue.
