Multiple Display Help

[spyder003]

I recently reverted to XP from Vista after learning that Vista (nor 7 sadly) supports span mode, turning two displays into one.

I started with a clean format/install of XP Home SP2, updating to SP3 via web. I have the latest chipset and video drivers installed for my machine. When I right click the desktop, go to properties, settings, click on the 2nd monitor and check "extend Windows desktop onto this monitor", nothing happens. I also have no options in the nVidia control panel for multiple displays. Both monitors are known good - if I swap DVI ports the 2nd monitor works. Also, both DVI ports on the video card work, I had multiple displays in Vista, just no span mode.

Setup is XP Home SP3 and a evga 9800 GX2 graphics card, both monitors connected with DVI cables.

I'm stumped on this one, any help would be appreciated.

Thanks.

Ok, I figured it out. The 9800 GX2 is a dual GPU card. I had to manually disable one of them for mutiple display in XP. In Vista I didn't have to do that, but no span support.

I can't win =/
