Dual Monitors using AGP Card and On-Board Video

[ShafferTech]

I am having trouble configuring dual monitors using an agp card and
my onboard video. I know there must be a way to get this to work as I
have done it in the past, just can't remember how. Any advice?

Usually the motherboard automatically switches input to the AGP card
if installed, and disables onboard video. I have never heard of
running dual-monitors this way, and if possible, would require some
way of leaving both enabled and disabling the bios switching system.

Any idea on how to do this?

If you bought a dual head AGP video card, you could run two monitors
from the video card itself. Then, the state of the onboard
video would be immaterial.

Sorry, unless there is such an option in the BIOS, I don't know of any
way to force it. You could contact the company that made the board.

Most onboard video cards use the AGP interface themselves, and as I
understand it, only a single AGP interface is possible due to
architectural/design issues.

In other words, a dual-head AGP card is the way to go.

On the typical board with AGP slot and integrated video, the
integated video is running from a logical AGP port. Because
AGP is a port not a bus, you couldn't run both even if there
were a way of trying to trick the bios.

The typical solutions are either:

1) Pull the AGP card out, install a PCI video card and use
it plus the integrated video.

2) Use an AGP card with dual monitor outputs.

3) Install a PCI video card and use it plus the AGP card.

4) Pull the AGP card out and install a PCI card with dual
monitor outputs.

If you install a PCI card you would have to decide if it
should be considered the primary display device and make
changes to that setting in the bios if required.

I guess I was wrong, thanks for the info all!
