OT- Monitor set up help required

[Gramps]

Posting here cause I figure there's a lot more people browsing this forum than in Technical Help...and I post here mostly anyhow, so....

Just got a new computer with the Nvidia 6800 GForce card. Trying to run two Dell 21" monitors using an adapter for one of them (just like I did with my previous computer).

When I start up the computer, my 2nd monitor shows the Windows logo, etc. so I know it's hooked up right (it goes blank once Windows is started up). When I go to Display/Settings to enable the 2nd monitor icon, there's no 2nd monitor listed. I've tried the troubleshooting steps, downloaded all the Windows updates, etc. but still no 2nd monitor popping up.

Any ideas? Should I get another adapter? Anyone with similar issues that they worked out? Took me the purchase of an adapter and 2 minutes last time, didn't think there'd be any problems.
