I have the HC3100 pj, and run in 720p and 1280x768 modes. using my xbox the 720p mode fills up the entire screen area, but my pc using 1280x768 only fills 3/4 of the screen area.

I want to know how i can keep the projector sizing equal so that it always fills the screen area? why does the xbox 720p fill up all of the screen and the actual max rez of the pj is 1280x768 does not?

any help making the 768 rez fill of more of the screen using a pc would be much appriciated.
