Sorry for my bad english but i'm french ^^"
I search with Google a solution for my problem but i find anything.
I need to use 2 screen with my HD7770 Graphic card.
But when i use the DVI port, the first working, and the second doesnt. I try every DVI port ( 2 ) one per one and they work. But when i use it in the same time. one screen dont work.
if anyone have a solution, its make me happy.
