I have an external NVidia graphics card and wanted to check if one of my softwares which I'm developing would work without a graphics card.

Instead of having to pull out the card, I wanted to know if there's a way to temporarily disable the card or make it invisible to the OS, so that the PC would run without using the card?

The card has a VGA and DVI port. The motherboard has another VGA port. Currently my monitor is connected to the graphic card VGA port because as long as the card is present, the motherboard VGA port won't work. So I'd eventually have to use the motherboard VGA port, but can't do so if the graphic card is detected by the OS. There were no options in the NVidia control panel.

First step will be BIOS, there's generally two options you'll be interested in.

The first one is graphic card priority, the actual name of the option will differ from machine to machine but it'll have options like:

PCI-E (or PEG) Onboard PCI-E/Onboard

For this one you want to select the option that shows both... the second option will generally be called something like Multidisplay and you want to enable that.

Between those two options you have both cards powering up and BIOS prepared to display stuff on both of them.

From there you can just go into Device Manager in Windows, right click disable the card you want to 'remove'
