The Sharp DT-300 accepts the following DVI resolutions,
1280 x 720 @ 60Hz
1024 x 768 @ 72,70,50 or 43Hz
800 x 600 @ 75,72,70,56 or 50Hz
(plus some more lower res's)
So in windows, your display setting should match one of the above. When the project detects a Resolution/Refresh combination that it doesn't like, it will just give you a blank screen.
Hope this is of some help.
