    I'm looking on ebay and have tried to research via google but I can't get any definitive answers to the question. And since it's quite a sum of money I need to be certain.

    I need to know the "oldest" powermac G4 or G5(cheesegrater) I can buy that supports 2 monitors(spanning, not mirrored). I found a 2.7ghz powerPC, saw that it had two DVI connectors, but could not verify if you could "span" two 22" montors.

    Is it just a matter of getting the right video card?

    Thanks in advance for any assistance you can provide!

    It has everything to do with the video card, of which pretty much all are dual-headed cards (except for the oldest cards, like the Rage 128s in the original G4s). The dual 2.7 G5 included an ATI Radeon 9650XT as standard, which included a single-link DVI and a dual-link DVI port. So yes, it would support two 22" monitors spanned, but it would only be able to support one monitor which required a dual-link connection (the Apple 30" display, for example).

    Any "cheesgrater" style mac is a G5 machine. I am almost certain that all of them can run dual displays spanned; I dont think Apple shipped any of these machines with a video card with only one output.

    That being said, alot of the older G5 machines have an ADC output, and a DVI output. The ADC output will only work on older (plastic) Apple Displays. You will need an ADC-to-DVI adapter (20-30 bucks) to run 2 DVI monitors. Note, this connector is NOT the same as the DVI-to-ACD adapter, which cost much more.

    Enjoy your new machine!
