With a 32 meg AGP card and a 32Meg PCI card I had no problems with two monitors.
Upgrading the AGP to a G-Force 440 SE 128 meg with video I find that the PCI card insists on being the first card and conflicts with the new one. The potential with this setup is to have two monitors to share all the desktop stuff and display the 'preview' on a tv screen.
Is there bios settings for which card takes preference? I cant see any. Thanks, Brian
