I'm trying to find data on the projection calculations for the IN80. I keep being directed to this website:-
Projector Calculator InFocus Corporation
but for the life of me can't see the IN80 listed.
I have a room which is 5metre depth, I want to ceiling mount the projector. I'm trying to find what what size screen is needed if I mount it say 4m from the screen. Any help would be appreciated.
Many thanks
