Hi everyone!!
Today I was watching a movie on my tv, which is my ''external monitor" for my iMac. I used VLC and it was full screen on my tv, I never had any problems with it. After the movie ended, I couldn't get my screen to work. I restarted, and it flashes a white screen and it does make the apple startup sound. Also everything seems to be working just fine. When I hook it up to my TV, I can use my tv as the ''main monitor" but my iMacs screen remains black. When I restart by pressing the on and off switch, I do get a flash of my current screen, but it fades to black quite soon after. So it's not the screen itself that has any issues.
I think I accidentally clicked something in the display settings this morning, but I have no idea how I can get my iMacs screen to work again. Does anybody know how to get my iMac back to functioning as a main monitor? When I unplug the thunderbolt cable, it doesn't switch back either.
It's a 21.5" late 2011 model by the way.
Thanks in advance!
