Projector Zoom to 400%

I am having an issue when I hook up a projector to my work laptop. I am using Vista Business. Whenever I attempt to project, my screen zooms to 400% and I see only 2 icons on my desktop. They fill the entire 15.4" screen.

The only way to adjust the screen back to "normal" is to log off as my user and log in as the administrator, go to personalize and adjust the display settings. Then log out and log back in as my user.

Any help would be appreciated.

Cannot really help much with this one apart from this
