About a 4 months ago I had a Catalyst that I interfaced into a nightclub. The interface from the TH2G went straight into their scan converter/scalers. What I noticed is that there is an invisible line of pixels on each side of each output of the TH2G. When I would shift and attempt to scale the image it would show up if I "zoomed out" too much (wrong term but you get the point).

I didn't think of this at the time but I just sent an email to Matrox to ask about this to see if it is something specific to the analog TH2G (or digital in analog mode) because that is the only place I see it. It has never been a problem using the TH2G in DVI mode.

Incidentally, a comment Richard, many times I have to ASDF my screens after making mix changes or when I restart Catalyst. Is this a bug you know about? Seems like a GL fault, right?
