I have been experimenting with exterior show on my MacBook Air. I had the exterior show arrange as a main monitor and my Mac’s built-in show as a secondary. Then for some unknown cause the exterior monitor stopped working. It simply sits there saying "no sign" however my Mac show stays as a secondary display screen. On this case I am unable to do something as all of the home windows stay within the exterior monitor that’s not exhibiting.
Once I unplug the exterior monitor the Show settings change, so I am unable to revert something:
So my query – the place do they retailer present show settings? Or, how do I reset them to their defaults?
(I simply need to say that that is such a silly UI if somebody has to ask this on a public discussion board.)
