hey guys, just a quick question, i have a nVidia GeForce 6200 currently, am just wondering, do you need 1 or 2 graphics cards to have multi-display??
RE: multi-display by ShawnZ on 11-21-2007 at 06:03 AM

RE: multi-display by Eddie on 11-21-2007 at 06:06 AM

if you have another free pci/agp slot then buy a cheapo graphic card and then you can hook up another screen
* -dt- is currently running three screens on two graphic cards

Often with a motherboard that has onboard video, the onboard video is disabled when a graphics card is plugged in in order to dedicate the bandwidth to the graphics card. I have seen motherboards where both can be used, but you'd have to check the motherboard documentation.
Edit: after reading adeptus' post i realized that the only systems I've seen using both a graphics card and the onboard were using a PCI graphics card.

quote:The reason is that the AGP bus, which is what most older computers use for graphics, wasn't designed for supporting more than one device. This is also why there haven't been motherboards made with more than one AGP slot. Your onboard graphics chipset, even though not physically occupying the slot, is connected to the AGP bus. That's why it needs to be disabled to use a card in the slot.

On the other hand, a dual head card is still only one device on the AGP bus. It is also fine to add a PCI card, because that's a different bus entirely (and can handle multiple devices just fine).
The PCI Express bus, different from the "old" PCI and used in place of AGP in newer computers, also doesn't have such a limitation.
