I use a "beamer" (love that term) at school by just connecting the RGB output on my laptop to the projector and it looks great. I'm not a fan of the big lyrics window, so I copy the lyrics to the "lyrics document" window, re-size the chord screen to the left and put the document window beside it (no scrolling lyrics of course). It seems to work better for me. Maybe I don't fully understand your question, but I would think the projector support would be a function of your computer hardware/software, not the biab program.
