[AG-TECH] Matrox Parhelia triple head AGP: 3 independent outputs???

[Bob Riddle]

I can look at this more closely tomorrow - but I believe there ar Matrox 
configuration tools that came with my Parhelia that let me choose to 
treat/not treat the 3 displays as one 3800x1024 display.  Maybe this was 
under the display options ... I don't remember as I am using it for 3 
projectors.
