Double wide res

Hi, My friend is trying to run blitz3d (demo) through a double widescreen output.

Basically he needs 2048x768 size. the special graphics card then cuts it in half in the width (to 1024x768) and displays it on a 3D monitor (our uni has one)

But blitz says its unable to set that graphics mode. He is running it on the PC that has the card (and it runs blitz in a normal res fine)

Just wondering if anyone else has tried this, or knows why it isn't working.

you cannot use fullscreen with a resolution not available on your computer: i think your computer doesn't recognize 2048x768 as a valid one, even if you have a double widescreen output..
However, have you tried to use 1024x768? is the resolution streched or not?

did you try mode 3?
