I recently picked up a used ATI 256mb AGP 9600 Pro Mac Edition video card.
Its got 2 DVI ports. I installed it in my G5 Dual Power Mac with OSX Tiger.
I have two new Dell Flat panel 17" displays. Using a DVI to VGA adapter
on both connectors, I can get one of the Dell monitors to display right,
the other flat panel just has vertical lines going across it...It seems like
the DVI connector on the left...is the issue...I can switch the monitor
cables and the problem switches monitors, the monitor I plug into the
left DVI connector has the fuzzy vertical lines. Can anyone suggest
what the problem may me???

Thanks,

You've ruled out the monitors. Need to switch the cables where they attach to the video card also and see if the issue follows the cable or the port. I'll keep my fingers crossed that it's the cable.

I read lots of info today on ATI and Apples websites...Now I'm wondering
if the card is the issue... I have the two brand new Dell 17" Flat panels
and the card has two DVI outs... but I'm confused about if their Dual Link or
single link and if those make a difference for the two Dell flat panels ???
The two outs on the card are DVI-I (Dual Link) Wondering if it only
supports one Digital Flat Panel????? Hopefully the card is not bad on Port one!

Welcome any Ideas
Thanks,
