I maybe should start a new topic, but since I have managed to determine that my sources behave this way when connected directly to the projector, the only factors I can think of are either the sources or the projector.....
I have a OPPO 103D and a DISH Hopper, which nicely fill my screen when fed to the RS20.
I have an Apple TV and a PS3, which have a shifted image -- about 5% to the right, when connected to the RS20.
I can "fix" this, by using lens shift.... but then the other sources are not aligned correctly.
I'm thinking it must be a projector setting. I pulled the receiver out of the mix, and am connecting sources directly for testing.
Anyone seen such a thing before?
