I have a Dell Latitude D830 which has onboard Intel video. I purchased 2 LCDs and a Dell D/Dock so that I could put a PCI video card in it and use both monitors along with the laptop LCD. I am running Windows Vista Business 32-bit and am having nothing but problems.
I have tried a Nvidia GeForce FX 5200 and ATi Radeon X1300 and both give me the same problem. When I go into device manager there is a ! over the PCI video card with the error message "This device cannot find enough free resources that it can use. (Code 12). If you want to use this device, you will need to disable one of the other devices on this system."
I have the newest BIOS for my laptop (A14) and have already tried disabling onboard devices in the BIOS and in device manager. I have tried setting the primary video card to dock and onboard, I have found someone with a similar problem here http://www.thoughtshapes.com/node/66
but I have been totally unsuccessful.
Basically all I am trying to accomplish is using my 2 external LCDs and the laptop LCD at the same time.
