Too big picture with projector?

I’ve got a Projector, but the picture is bigger than my screen and I can’t move my projector. I’m currently using a Media center PC and I just wondered if there was any application out there, which can actually make a windowed picture with black around it?

You either need to adjust your current lens or buy a long-throw lens to focus the picture on your screen.

RTM = Read The Manual.

Some video cards on a PC have an option to reduce the size of the screen.
Right click on your desktop->Properties->Settings->Advanced

thank you. You mention 2 options a long through lens and the graphic card. Can I get some 3rd party drivers to the geforce 6600 which can reduce the screen size?

Not sure, I don’t have any current Nvidia video cards to try out …
But you can start by looking here.
