When you open Nvidia controls the tv/video is listed on left of the window.Also listed there is setup multiple monitors.
I would update your graphics card via Nvidia website.
ForceWare Release 169 this will require a reboot.

Downloading fresh drivers will reinstall your Nvidia controls.
Look in device manager see if these are listed there?You can right click and update drivers from there.
What operating system are you running?XP?
