I just got a mac G4 and it has a geforce MX video card. I am using two samsung 213t LCD panels. The card has one ADC connector and one regular DVI. Is there some way to make the panel on the DVI connector the primary monitor ?

I have a DVI KVM and the combination of the ADC to DVI converter and the KVM causes strange colored lines. When I run the regular DVI connector through the KVM to the monitor it looks great.
