I have a problem with my gigabyte radeon hd 7970 oc.
Firstly if I turn on the pc first and then the tv (lg 42lmm660s) the screen stays black and I see "no input". If I turn on the tv first everything is fine.
Secondly if I turn off the tv and the pc is still on (like i'm downloading something and go to sleep) when I wake up and turn on the tv it's all black and shows "no input" again.
I have no screen saver and in power managment settings i disabled turning the monitor off.
Any ideas? It's quite frustrating.
