I just bought a Mtrox G550 dual-hed with one connecter DVI. It comes with an adaptor to allow you to use two standard VGA cables. I installed RH 7.3 and then used the Matrox powerdesk app to configure dual-head, which it seemed to do successfully. However, I cannot get any output out of the DVI port. Anyone know a sure way to tell if I have a bad card or not? The DVI port is labeled as port 1 but when I installed RH it chose the standard VGA port as it's primary display. Any ideas?
