nope, can't change the resolution. Just tried, and it blacks out all three of my monitors, and stays blacked out even when I alt tab out of the game.
edit: I have noticed that if I hit alt tab, and then keep the alt key held down, I can see the game again, until I let go of alt. Then the screens go black again.
Everything this guy said, me too.
