Hi -

I'm using an HP-Pavilion with an AMD64 processor running WindowsXP (about 3 years old).

I used to use only one monitor, through the on-board port. Then I bought an extra lcd and a video card: G-Force 6600 NVIDIA, Video BIOS version 5.43.02.69.51, IRQ 18, Bus PCI Express x16, Memory 256 MB, ForceWare version 77.77

Now I've acquired a 3rd lcd and want to run it also. I've got 2 plugged in to the G-Force card and they work great, but when I plug the 3rd into the onboard port it doesn't get a signal.

Any suggestion? Will I need to buy another video card? I don't see any cards out there with 3 ports on them.

thanks for anyone's help :)
 
For a three screen setup you will indeed need another graphics card - the only single cards on the common market capable of outputting to three screens are the 'two cards in one' dealies like the nvidia gtx 295 - and even then SLI has to be disabled.

Now it may be the case that you can run the third monitor on the on-board GPU of your motherboard but your graphics card has disabled it - you will need to check the BIOS to see if there is a setting you can utilise.

If you run into difficulties do let us know your motherboard model number and revision.

Hi - thanks for your help.

I checked the BIOS and it's currently set at "PCI" for the Video Port. The only other choices are "PCI-E" and "Onboard". (I don't see an option to run both, but I'm not sure what the "PCI-E" setting means).

If I set it to onboard, will it also see the PCI card and power all three outputs?

Thanks for your help!!!

Hmm, I'm not sure as Ive only ever set up tri-monitors on proper graphics cards - give all the options a go and see if you get anywhere :)
 
Motherboards tend to disable on-board graphics when using your own video card.

To get the third monitor working just buy a cheap graphics card with one output.
