I am setting up my wall screen and noticed the bottom of the picture, with test pattern or DVD, is about an 1.5" narrower then the top. The projector is mounted from the ceiling and I can't find anything in the menu's to bring the bottom out or the top in. If I use a level on the top it seems to be in about 3/4" on each side.

I know from using projectors at work for PC's there should be a way to do this but I am having zero luck with the manual or trail and error.

Find your keystone adjustment,that should take care of it.

Took some digging but I found it..But I woiuld have no idea what Keystone was :)
Thanks again!

If you don't notice it without displaying a test pattern, you may want to simply leave it. Remember that the keystone adjustment works by tossing out a wedge of pixels on either side of the image, so you will reduce your resolution a bit. I left mine alone and made the black mask around the screen fit the image. No one has noticed it and I only know if I put a level on the edge of the screen.

Another option to avoid the dreaded resolution killer of keystone correction is to tilt the screen. If the difference in size is that small I would either do nothing or tilt the screen.

Keystoning is EVIL I tell ya EVILL :p
