another thing to look at....

see if your projector is set to display native resolution.
ie, it will display the resolution it's receiving. which
connection are you using from the DVD player? it's probably
outputting 480i(or 480p). so the projector is only using
640x480 pixels in the middle its display matrix, instead of
the full 1280x720.

you have a Bravo D2 unit. try using the DVI output and set
its output to 720p. this will scale the video to match the
BenQ exactly - pixel for pixel. V Inc made that DVD player
for the purpose of using DVI anyway.

cheers.
