I currently own a computer that has an ATI Radeon Video Card (pci Express X16), and a on board NVidia video card. When I got my Radeon Video Card, I used duel monitor with it with its two DVI outputs. Anyways, I want to use one of its two outputs to connect my computer to an HDTV, and connect one of my monitors to the On Board video Card. Whenever I try though, it says that my drivers for that card are for an older version of windows. Here are my exact cards: ATI Radeon HD 2600 Pro NVIDIA GeForce 6100 NForce 405 (onboard card) so is there any way i can hook up a monitor to the onboard card and make it work, while still using the Radeon card?

Installing a PCIe video card automatically disables the integrated PCIe graphics. You can't use both at once.

OtheHill is correct ,you either use the PCI-E video card or the intergrated ,almosrt always the PCI-E card is the better of the two ! You actually should open the BIOS and make sure the intergrate graphics is disabled and the PCI-E is picked as the go to for your graphics ,you can disable the intergrated graphics in device manager if you dont want to mess with the BIOS. I have an ATI RADEON PCI-E x16 graphics card and it has dual monitor capabilities ! Have you checked into your cards specs to see if it offers this or simply looking and the card from the back of your case you should see two monitor connectors ? Good Luck ,Nick

If I understand correctly, you want to run 2 monitors PLUS an HDTV? As OtheHill stated, you can't run both PCIe & integrated at the same time, however, you *may* be able to install a standard PCI graphics card & run that along with the PCIe.

"Installing a PCIe video card automatically disables the integrated PCIe graphics. You can't use both at once." That's the case for almost all mboards with onboard video, but there are a few recent mboards that have chipsets that have the capabilty to have both enabled at the same time, if you use certain video cards compatible with that chipset feature (both AMD and NVidia have some recent main chipsets capable of that). If the video card you use is not compatible with that feature, the onboard video is automatically disabled. "You actually should open the BIOS and make sure the intergrate graphics is disabled " There is almost always no setting in the bios setup that can specifically disable the onboard video, or any other indication that it has been or not. If it has been automatically disabled, the bios ignores all settings in Setup to do with sharing ram with the onboard video, and all the ram in the slots is available for use by your operating system, and the onboard video display adapter does not appear in Device Manager. However, there is a setting in the bios Setup for Intialize video first: xxx, or Primary video: xxx, or similar - that must be set to the proper setting in order for your video card in a slot to work to it's full capabilties in Windows. E.g. if the card is AGP or PCI-E, that setting should be set to that, or to video in a card slot rather than whatever onboard video - if that isn't set correctly automatically, you must correct it. If you have already installed drivers for the onboard video before you installed a video card, you should un-install any drivers and associated programs found in Add/Remove Programs for the onboard video, preferably BEFORE, or after, you install the video card in a slot, and Un-install the onboard video Display Adapter found in Device Manager, BEFORE you install the video card in a slot.
