Have three monitors, one of them is rotated by 90 degree. Configuration is carried correctly...
...to the stage "Bezel compensation": now image on that 90-degr. monitor switches automatically to zero degree!

The only solution is to set up Eyefinity until "Bezel compensation" - without running the function. It's frustrating...
