lcd + vga-port configuration help needed

[raphaelb]

hello users

I have a notebook with lcd 1920x1200 and a vga-port. Now, I want to connect a beamer (it can handle a max. resolution of 1280x960) to the vga-port. The idea is to clone the main-display.

but with nvidia-settings I can setup a working config, but with the cursor i can move the desktop because the resolution is too big for the beamer. And don't say, buy a hd-ready beamer.

I don't want desktop-switch or something else, only to watch movies on the beamer.

have you any tip for me...?
thanks
