There seems to be some problems with the 8800 series and Matrox Triplehead, and I just got this confirmed by Matrox support.
My problem is that in the highest resolution (3840 x 1024) quite alot of disturbance appears across the span. It increases in strength the farther to the right you go.
Older models did not have this problem.
I am wondering if any of you have a working setup with Triplehead + 88**, and of course which brand and model you use..?
