    My computer (a Dell Inspiron 620 desktop) has a VGA port and an HDMI port built onto the motherboard for integrated graphics. I have recently installed an Nvidia GeForce 630 2GB dedicated graphics card, and it has 2 DVI ports and 1 mini-HDMI port.

    I have a DVI monitor and a VGA monitor (DVI-VGA adapter used) connected to the graphics card. I was trying to connect a projector to the VGA port on the onboard graphics, but I couldn't get it to use the onboard graphics with the card installed. In BIOS > Advanced > Graphics Options, there is one setting: Intel Multiple Monitor something. It has two options: Auto and Disabled (currently Auto). Its in-BIOS description states that it can use both onboard and dedicated cards to run multiple monitors. However, no luck.

    Windows has shown a third monitor in the display settings, with a bunch of "Attempt VGA Connection" options. Selecting one and choosing Extend Desktop opens a "Unable to Save Settings" error. Ubuntu does nothing to recognize anything.

    Is it possible to use both the onboard and Nvidia graphics together? Or am I better off buying a mini-HDMI to VGA adapter and connecting it to the Nvidia card and the projector?

    Thanks for reading all my extended description.

    PS: I would like to get this working in Ubuntu (currently 13.04), but getting it in Windows and Ubuntu would be a bonus!

    Most of the time, no. Installing an addon card disables the onboard chipset.

    That's what I figured, but I wanted to specifically ask because of the BIOS option.

    Thanks!

    The BIOS setting you reference is likely related to the onboard chipset (when only using the onboard chipset).
