I was using safari to watch netflix on fullscreen, and suddenly my display split like the photo below.
I can fix it by going to Displays and changing the resolution to Default.
I'm just wondering why this happened? Is there a fix to this so that I don't have to keep going back to System Preferences -> Displays to fix it.
