On board DVI and HDMI at the same time

Is it possible to use the on-motherboard HDMI and DVI at the same time? My efforts to connect two monitors (DVI and HDMI) to an AMD motherboard with 880G chipset did not avail. Even a Gigabyte video card (GV-N210SL-1GI GeForce 210) with DVI and HDMI did not work at the same time.

Is this supported in newer motherboards and newer video cards?

Thanks

Some motherboards (MSI AMD AM3/+ boards, I'm looking at you), have either a BIOS selection, or in my case, a physical jumper block to "select" between the DVI and the HDMI.

But a discrete card, well, most of them, have enough TMDS links to drive at least two digital (DVI, HDMI) outputs at the same time. I'm really surprised that your video card didn't do that. Did you properly install the drivers, and connect monitors to both outputs? Because some cards don't drive both outputs for the BIOS screen, or without loading drivers.

On-board video card did work with two monitors even with updated drivers. I did not install any drivers for the PCI-E video card, hoping that the Windows' built in drivers would work :) I am going to try that now!

Edit: It worked with the new NVIDIA drivers! Thank you!
