Force Mac to detect displays?

Force Mac to detect displays? 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.

"This is really old but I found a solution that still works in OS X 10.11.2:

hit cmd + ""brightness up"" for display detection and cmd + ""brightness down"" to switch between mirror and extend display modes. It seems to be the brightness keys and not necessarily the F1 and F2 key."
