Recently I just finished a build with XP Pro. The graphics card is the XFX
Nvidia 8600GTS with 512MB memory and 2 x DVI outputs.

However, I can't extend my desktop to the second monitor. I have two
monitors plugged in yet windows is only detecting the one output. On my
laptop it shows 2 black squares with 1 and 2 representing the two monitors,
here I only have a picture showing a monitor with the desktop blue background.

Why is it not finding the other output?

The drivers are the latest ones from the Nvidia website?


Thanks!

Save the file and send to nVIdia tech support. Or, open System Properties
and disable the onboard video and reboot.
