Learning debugging in PhpStorm and keep accidentally hitting Ctrl + Alt + F8. I use 3 displays this disconnects the two remotes and goes bac
Something else to try in order to return to some sort of working order quickly...
If your using windows 7 or newer, you can always try getting your screens back by pressing the window key (on the keyboard-bottom left) and the P key at the same time. This will bring up options normally as to how you want your screen to be projected (single, dual, or extended displays). If you tried Win + P and still cannot see anything, try pressing the down arrow on the keyboard. This should bring the display back to normal mode(s).
