I have a DP800 quicksilver that came with an Apple supplied Geforce3 video card. At the time it was a great gaming machine for what was available to play 8-) but these days I just use it for video editing. Anyway, I have two Sony monitors now, one driven by the geforce card, and another running on a old PCI ATI VR 128 card. The machine won't deep sleep with the ATI card in though. Not really an issue, but I would love to free up the PCI slot for another card. So I bought a ADC to VGA adaptor of ebay. Hooked it up and nothing. I figured it was a bad cable, but when I switched my main monitor (hooked to the Geforce3's VGA output) to 640x480 I did get an image on the second moniter that was hooked to the ADC-VGA adapter plugged in at the same time. It was a mirror of the main monitor though. Under the moniter display prefs the OS doesn't "see" the second moniter. After trial and error I discovered that any moniter settings above 832x624 gets me no image on the second moniter hooked up via ADC. Anyone out there driving 2 moniters on a Geforce3? Better yet, anyone got it running beyond just a mirror of the main moniter? I would love to have a regular dual-display setup and lose the PCI ATI card I was using.
Thanks in advance.

The Geforce 3 is not a dual-display capable card. You'd either need to buy a different AGP card or add something like a Radeon 9200 PCI card to get the second display working.

Ya, like I said, I have a PCI card already installed driving the my second monitor, I was just hoping to free up the slot for another PCI card and let the Geforce3 drive 2. Guess I can't unless I want it mirrored (I don't). Whats the cheapest AGP replacement card I can get that will drive 2 monitors? Just for video editing, don't need Geforce6800 power 8-)
