All monitors are 1900x1080
Not using Eyefinity (but it works, I tested it), just extended desktop.
I tried the games in all different modes, Windowed, Windowed fullscreen, Fullscreen, same problem every time.
This is actually the second adapter I am using, my first MiniDP->DVI adapter (also an active one) didnt work at all.
One additional piece of info however, I have been using only 2 out of 3 monitors until the problem is resolved, and I dont have any issues with just 2 monitors.
