How can I send a VGA signal from my video card AND my motherboard.  I
recently installed an AGP ATI Radeon 7500 video card on my PC, but I
can't get a VGA signal out from my motherboard.  I've searched through
all the BIOS on my motherboard's setup, but I can't find the right
answer. PLease help.

aikiliano.. basically what you are saying is that the new video card
and monitor aren't communicating?

The new video card is working fine.  But I also want to utilize the
VGA out built into my motherboard.

This depends entirely on your motherboard. First off, most new
motherboards will automatically detect wether or not something is in
the AGP slot, and if it is, it wont initalize the onboard VGA. This is
also true if you manually set the onboard VGA to the on status (If
your motherboard even offers a setting like that in the bios) However,
I believe Windows ME and above support what is called dual monitor
support. Meaning you can have two video cards running. Assuming your
video cards also support this feature. But to answer your question
specifically, no you cant force your motherboard to use both onbard
VGA and a video card. This is a hardware limitation. No getting around
it.

Do you know the manufacturer of your motherboard, or computer model
number also the BIOS, or CMOS software name could be useful.

I would assume that the built in graphics on the motherboard would be
on the PCI bus, you may look for anything under advanced PCI bus
settings, or integrated peripherals.  This is where the award bios and
CMOS setup utility locates the integrated hardware.  I had to
manipulate these settings to initiate my own board audio.

Also if your mother board is incapable of providing a second VGA
output, you could possibly add a PCI VGA card for very little cost.  I
know that office depot and OfficeMax offer these cards for generally
around $60.00 to start.  Be informed that the PCI bus is much slower
than the AGP, and would not perform quite as well, but to be used as a
second monitor this may be able to solve your problem.

I currently working in an engineering related field where I use Duel
monitor systems all the time your secondary monitor is normally going
to be used for managing multitasking in office related tasks, but if
you were to pick up a game or something full screen it will default to
your primary monitor which I would suggest using your AGP card for
that.

The onboard video on most modern motherboards is supplied via the AGP
bus. If you put a card in the AGP slot, the onboard video will
automatically be disabled. This is because the AGP bus cannot handle
more than one video card. A solution for you would be to get a PCI
video card (for your 2nd display), as it and AGP cards can co-exist.

Something like this would do just fine.
