2 Display Adapters

I am upgrading a computer attached to some research equipment, and the computer I have has a Dual-Video out, but only 1 Display Adapter under Device Manager.

The software checks for 2 adapters, and since it can't find it, it quits. Is there any way to force the video card to put 2 display adapters under device manager?

Normally all you would need is the correct video driver and a dual adapter that connects on one end to the video card, and the other two connections go to each monitor.

What "software" are you referring to? What hardware is involved?

The software runs the research equipment. It does data collection on one monitor, and presents images on the other monitor. So it needs 2 separate displays - and instead of checking to see if there are 2 monitors attached, the software asks system32 if there are 2 display adapters.

Oh, and the hardware was a typo. It's a Radeon HD 3200 onboard graphics. The MB has D-Sub and DVI/HD out. [The bios lets me choose D-SUB/DVI or D-SUB/HD]

If there is choice in the BIOS as to which output to use it is pretty certain you can only use one at a time otherwise you would have an option for both.

You need another display adpator.

Well there are 3 outputs on the video card - D-SUB, DVI, and HDMI.

So anyway, I got it to work. For posterity sake, the solution was 8.12 Drivers, and selecting the D-SUB/HDMI option. It put D-SUB/HDMI on one video "out" and DVI on the other video "out" and now the software recognizes the D-SUB and DVI outputs as separate.

Still only displaying 1 Video Adapter though... so now I have no idea what the software looks for (or what the drivers are emulating). Sigh.

There should be an option in the BIOS screens to enable the second video output. Then you will still need to configure it with the software.
