So, it would be possible to configure all 4 monitors as parts of one 
logical DISPLAY??
Just clarify: At the moment I use two dual head ATI FirePro 2270 
graphics cards. As a consequence I have two logical (dual-monitors) 
DISPLAYS and the problem is that I'm not able to span a single window 
across more than 2 monitors.

What about: Gigabyte Radeon HD7770 OC?? I know, it's OT but maybe 
someone has experience.
