dual monitors not working

I have two graphic cards and Win 7 will only let one work at a time. I have updated the drivers both to windows 7. This is driving my crazy.

Thanks for any help.

Hi. Which cards?

If one uses a WDDM 1.1 driver and the other a WDDM 1.0, it's no go can't be done type of stuff.

Plug both monitors into the better graphics card and problem solved.

Oh yeah. I know about those cards a little. Get the latest driver from their site for you card. Get 7 driver and if not then Vista.

Install using the device manager for each card the same way:

Update driver software. Browse my computer. Let me pick. Have disk. Browse. Navigate to and double click on the .inf. Hit ok. Hit next and let it install.

After doing for both cards, reboot and then choose an Aero theme.

The card s kind of on the rare side. If you need more help, search my screen name on here and Matrox. You'll find previously successful examples. Or let us know here too. Good luck.

If you have any exclamation points in the device manager, let me know.

How could you have 2 different cards? Your post above says, "2-matrox Millennium g450 dual head DVI PCI"

???
