Since the distance for 120” is too large for me, I thought of building a shelf mounted to the wall, that can be pulled out (i.e I can push and pull it from the wall).
that way I can push it when no one is watching, and then people can move around freely in the living room, and pull it out for the distance needed to get 120” image when I want to watch.
Do you guys heard of such shelfs/similar ideas? I know it has to be strong when pulling it out because the projector is about 10kg.
The other option is to mount it on the wall to project from above, but I’m not sure that’s possible and might also hurt the effectiveness of an ALR screen.
