Using 3 monitors on an Asus P7H55-M Motherboard

I am trying to use 3 monitors on a Asus P7H55-M mobo. When I change my bios setting to utilize iGPU & PEG for mutlple monitors my Vista OS disables my ATI Radeon HD 4300-4500 PCIe card. Only the integrated VGA fires up. If I were to use an ASUS 210SLDI1GD3V2LP NVIDIA GeForce 210 1024MB GDDR3 PCIe 2.0 x16 Video Card would I be successful with my 3 monitors?

Will probably not make a difference.

You will need an additional VGA card to use, instead of the onboard one.

My guess is that your problem is with Vista drivers not your mother board.

Some MBs will not allow you to use built-in video card with an PCI added video cards at the sametime.

My suggestion is disable built-in then purchase another video card that is the same model as your current PCIe card.
Free Tool: Port Scanner

Check which ports are open to the outside world. Helps make sure that your firewall rules are working as intended.

Very rarely can you use the onboard AND a double header graphics card. One or the other only I am afraid.

Is this the reason for the crossfire type mobo's? Multiple PCIe slots vs. the standard of 1? The bios on this board I have has multiple options utilizing iGPU, PCI and PEG. All combinations won't allow the 3 monitors in combination as I was hoping. That's why I thought possibly having an Asus mobo and Asus vid card might work?
Since you are using vista you will need 2 cards that use the same driver, the 3 video options you have posted all use different drivers and will not work together. You'll need to get another pci video card that uses the same driver as the ati card or the nvidia card for 3 monitors.

Go for a AMD HD5xxx series Eyefinity card to support upto 3 simultaneous displays.

Make sure they come with a DisplayPort and you will probably require an active DP to HDMI, DVI or D-Sub dongle to drive the 3 monitors using the 2 other video outputs.
