Picked this up at the Humble Bundle and I've already played it before on Xbox - but it's a good game, so I got it again. For multi-monitor users, you can't select anything over 1920x1080, but using the following method I was able to get it to work in surround @ 5760x1080.
You have to use it in window mode - with http://steamcommunity.com/groups/WindowedBorderlessGaming
but it works like a charm. Trying to force the game via config to your resolution full screen doesn't work.
After you get it running in Borderless window mode you can edit the pref.ini located:
SafeWidth=0.330000 <----change these values to your liking (this is for centred GUI, on 5760x1080)
SafeHeight=0.970000 <--- change theses values (5760x1080)
