Hi I'm using win7 and have my television connected to pc so to see videos on it. I have turn on hibernation so that I can quickly shut down and start my computer and that everything is restored, problem is that when starting after the pc is hibernated, my 2nd screen (TV) is black. In display settings it still says that i extend the desktop. To solve the problem i have to make changes so that i can apply the settings and then go back to extended screen again. Anyone know why this happens and what i can do to solve the problem once and for all?
