Onboard VGA & Graphics Card for 3 screens?

[rjpalka]

Hello.

I have a Dell Dimension E520 with an onboard VGA port and a Radeon X1300 card in my AGP. I would like to use the onboard VGA port as my 3rd screen. I plugged it in and it is not recognized. I think it is an intel Chipset. I am using Windows 7.

Any idea on this?

Thanks

I think that you can't use both GPUs at the same time especially when you are dealing with such old hardware.
