Dual monitors

I bought a new PC with DVI and HDMI ports on the motherboard and I would typically use both to run dual monitors. With this particular PC, the graphics card port overrides the motherboard port such that I can't run both at the same time, and the graphics card only has one port. What is the most affordable way to run dual screens while still being able to leverage the graphics card?

Thanks very much.

You should be able to force enable the onboard GPU via your BIOS.

One thing to note is not all CPU’s have the integrated GPU so you may want to see if yours does.

I'll lose the advantage of the card if I do onboard, right?

If you tell your games to display only on the card's screen, things should be fine. If you try to run on the wrong screen, or try to use both for a game, you'll probably have serious framerate issues, if the game doesn't outright crash to begin with.

Of course, all that's dependent on you having video circuitry on your CPU. If you don't, those ports won't be active unless and until you replace it.

edit: there's some tech out there to let an Intel and an NVidia card share a screen. Maybe it's called Optimus? But I've never done anything with it, so I have only the vaguest idea what it does. I have the impression that it runs the motherboard port on Intel graphics until it comes under real load, and then switches that screen over to the video card. But I could be entirely wrong, or I could be backwards... it might be sharing the video card port instead.

Someone here's bound to know more about it than I do.

If you set the monitor running from the graphics card as primary display games will show on that one.

Running both gpus causes a bit of performance overhead and increases power usage slightly, but these are pretty minimal.
