try setting the res to your single screen desktop res in safe mode, sometimes vista remembers that and carries it across to normal mode
Tried that but it was a no-go.
But I used Driver Sweeper and removed all the Nvidia-drivers/software
so now I'm running in normal mode and have successfully uninstalled Matrox Powerdesk..
I'm gonna reboot and then install latest Nvidia drivers (181.20) to see if it works. Then after that I'm gonna try the latest Matrox Powerdesk.
I'm just wondering what the hell made my Matrox flip like this.. :S
Edit:
After I installed the new Powerdesk every screen goes "Out of range".
55hz !? What and why did Matrox do this!?
