I have a Mac mini in a somewhat complex home-theatre setup. Often the Mac won't correctly recognize the TV as a display. The TV will just report "No signal". There are two methods to recover from this state.
- Unplug the display cable from the Mac and plug it back in
- Sleep the Mac and wake it up again.
Both are a bit cumbersome. Is there any way to force the Mac to re-detect or re-initialize it's displays? I've tried Command-F2 and a couple AppleScripts but nothing seemed to work.
1Good tip, but it's hard to press a button when you can't see the display :) – amrox – 2016-03-15T19:53:03.673
Nope the button does not work. – Sephethus – 2016-11-25T23:45:39.543
2Great -- option key does the magic. Wonder why they hide it!? – DustinB – 2013-04-08T19:09:41.787
2Unfortunately even this doesn't seem to always work. It still splits over two displays :( – Nicholas Tolley Cottrell – 2013-08-08T18:42:18.933
