I'm running a training course and using PowerPOint for Mac on OS X 10.10.3 on my2014 MacBook. I'm connected to a VGA projector. The MacBook has lost the connection to the projector and no amount of shutting things down and restarting has fixed the problem. The "Detect Displays" button in Preferences-Displays produces no result.
The projector connects up properly to my iPad, so the problem seems to be in the MacBook.
Any ideas?
