I've got Matrox G550 and Parhelia cards (both dual head) around as part of the work I do for one of my clients. I know that my colleague who does the software runs them in non-standard modes though still with fairly high dot clock speeds. The G550 in particular has always seemed very tolerant of any abuse we've hurled at it. In particular we have meddled with the master 27MHz clock and the G550 never complains. The Parhelia on the other hand is a touchy little devil and will crash the PC at the slightest provocation. The Parhelia is an expensive card so it's not really suited to the FothTV project unless you have one lurking in the junk box. At least FothTV won't involve mucking around with the hardware on the graphics card.
