I have a friend who has a dell laptop less than 2 years old with XP. She has done presentations with monitors before, but now it just displays a blank wallpaper no matter what is on the laptop screen. I checked it out, and I could drap windows off the laptop screen to the right and it would show up on the projector. It was like the projector was running a tiled instance to the right of the laptop screen. I have never heard of this, and cannot even find a setting for it? I could use the projector fine with my laptop, (and others) just fine. Any help is appreciated. Thanks Jason
