I am having a Problem with my video card not letting me run an addition monitor off the vga output on the motherboard. I know it works because I can go to the bios and change it and it works but they want...
When using a PCI or PCI-E graphics card, it will disable your standard VGA output port because the up-dated graphics card and your factory VGA port require different display drivers. Usually, the drivers are conflicting and will make your system unstable and cause it to crash. In short, you can't use both at the same time. I have a Radeon HD 5450 graphics card installed on my PC and it too has disabled my standard VGA port. If you are trying to use more than one monitor, you have to install a graphics card that supports a multiple display output. The graphics card will either have 2 VGA ports, 2 DVI-D ports or 2 HDMI ports or even any combination of the 3. My card, for example, has 1 VGA, 1 DVI-D & 1 HDMI. I can run up to 3 monitors at a time via my graphics card, but I cannot run a 4th monitor from my factory VGA port. My graphics card uses ATI/AMD drivers while my VGA port requires the use of Nvidia drivers.
I hope that you find this useful.
