I only have 1 monitor, yet vista display settings always lists as having 2. Only one appears in device manager. Is there a way to remove the second monitor?

Your Video card is probably *capable* of running dual displays, such as adding on a projector on a laptop for presentations. Don' worry about it, it is not hurting anything and you cannot get a virus from it, or anything like that.

The mindset from long ago of "I should delete anything that I don't need" is just that - of long ago. That mentality is not nearly as applicable today.

Of course, if you have a *real* reason for needing it to go, I am all ears.

if you dont have it there then its like having a second monitor but not switched on, the fact that you can take a screenshot and not have 2 desktops is meaning that its disabled, if you are afraid of it using resources up, then all you need to do is , right click desktop>nvidia control panel>manage 3d settings>multi display/mixed gpu aceleration menu and select single display performance mode. viola single display use only...
