so I'm waiting on my screen to arrive and have already mounted my Sony HS-20 on a ceiling mount (actually mounted to a shelf mounted to the wall).
the mount (from perfectmounts.com) allows for adjustment in all three axes. two of the axes are easy - just use a level to get the projector parallel to the ground (e.g. level) and hope that the opposing wall is perfectly vertical.
how can I accurately get the rotation of the projector right (e.g. rotating it about the vertical axis - making it "look left" or "look right") so that it is staring at the middle of the opposing wall? I can look for keystoning but it seems like a very delicate, arbitrary approach.
once I have the projector facing perfect to the wall I can trace the spot on the wall and mount the screen.
any hints?
