    I have an ATI Radeon HD 4300/4500 Series dual video card and I am running 2 monitors just fine but I want to be able to also hook-up a 3rd. monitor to my on-board video connection. I used to be able to do this easily with WinXP but with Win7 it appears that the video card supersedes my on-board video output every time or if I change the bios and have it look for my onboard video connection then my external video card does not work. I have used different external video cards and changed the bios all to no avail.

    Is there a trick to getting my on-board video to work simultaneously with my external video card using Win7 Professional?

    Thanks for any help with this.

    Using onboard chipsets and a video card together are typically a hardware issue. Most often, you cannot use both as the motherboard/BIOS disable the onboard when a video card is present.

    If this exact hardware has worked in this configuration in the past (ie: with XP), it should work now as well. If not, I'd suspect a driver issue. There isn't a Win7 restriction that I'm aware of.
