Is there a Overhead Projector that has the ability to adjust the screen size without moving the projector. I understand it is the len that controls this but cannot find a projector with this adjustable len capabilities.
We have a projector mounted in at the ceiling 18' from wall, it is used at this point for full size screen 7'X12' image for a simulator software program.
We need to use this same room for Meeting/conference/presentations also the projector needs to adjust the projection screen size to approx. 5'x5' image.
