Onboard AGP and AGP Slot at the same time

Hi All,

I was wondering if it was possible to us the onboard AGP video of the Asus A7N266-VM simultaneously with a card in the AGP slot, to achieve a dual monitor solution, or do I have to use one or the other and not both?
 
So you mean to tell me that their isn't anyway to have a dual monitor machine? Or did I just misunderstand what you said.
 
I meant the onboard graphics. I know it must be disabled if you put in a PCI video card. Do a search on Google for "dual monitor system" and you'll get a whole bunch of hits.
 
I believe that the agp bus is made for only one device at a time. Generally onboard video motherboards don't dual well. Some are set to be disabled any time another video card is in the system. You would have to use a pci video card to try it. I've had very good luck using voodoo2/3 pci cards in dual systems, onboard motherboards included. I've also had poor luck using nvidia products in dual set ups. YMMV
 
Onboard graphics with an AGP card, no.
Onboard graphics with a PCI cad is most likely yes.
In my experience you can use onboard video with a PCI video card just fine. You can not use onboard video with AGP since they both use the AGP bus. Only one or the other can be used at any one time.

EeyoreeX-- Does that depend on the mobo or chipset? Every time I have done a re-install on this computer (Dell) either in 98SE or XP Home, I have had to disable the onboard video Intel 8210 Graphics Controller before I could run my Radeon. Have I been missing something? Is this machine THAT far outdated? I refuse to buy a new one until Time Warner moves the last two miles and gets to my house with Road Runner.
 
ATI makes a dual display PCI and AGP card. and Matroxx makes a 3 one i belive. or a KVM switch(or splitter) could accomplish the same.
 
helpmeout: Mostly the motherboard, I think. I also think it also has to do with the BIOS and the way it is programmed, in that it might require you to disable your onboard graphics. I also know I did have this issue a couple times in older Compaq systems, wher eI had to disable the onboard video. But mostly in newer machines this has never been a problem. As was suggested and if you plan on keeping your current computer for a while, there are a number of video cards that provide dual monitor support. This is often a better and more elegant solution.

AEB: A KVM won't help as KVMs are for sharing one keyboard, monitor (video) and mouse between 2 or more computers. A splitter would help, only assuming you wanted to mirror the desktop on two displays and not run with an "expanded" desktop.
