I was about to open a new thread when I stumbled on this one.
My question was how do you position a ceiling mounted projector that does not have zoom and/or shift memory in order to only have to zoom in or out to have a 16/9 or a 2:35 picture.
The way things are said here it seems that it is an impossible mission. Is it?
Forget about the lens solution, why can't there be a position where the zoom is moving around the "right" axis in order to get the top and bottom black bars in 16/9 away from the screen in 2:35 and keep the picture centered?
BUMP: Is this thread dead?
