Reading the Table
From the upper table on this page, to project wide images on a 80 inch screen, install at about 0.768 m from the front.
Also, from the lower table we can see that about 1.066 m are required from the projector's lens center to the upper
edge of the screen. Use this to see whether or not enough height can be provided from the projector to the ceiling
and for installing the screen. The diagram shows the projection distance when the projector is installed horizontally.
