Re: Dual-head Matrox, monitors at different resolutions?
Hi!
The attached XF86Config-4 configures the dualhead mode on a Matrox G550
under Debian with the same resolution but different refresh frequencies
for a Sun GDM Monitor and a ADI TFT display.
We'd problems running the display at the digital port of the G550, so we
attached the Sun monitor to the digital port (via adapter) and the ADI
display to the analog port.
