HD 7770 dual monitors issue

[Nikolas Tantis]

I connected 2 monitors on my hd 7770 card but i can only get 1 at 1920x1080 resolution, the other one does not go at that much even though it says it can. If i connect the second monitor and make it main display then again the second one will not go full screen!

Download latest drivers and I think its because the gpu is not much powerful.
How are you using your dual monitors?
