Setting Up the Screen and the Projector
Use this to get a general idea of what the screen size will be when set in a certain position, what size screen you will
need, and what distance you will need to project images of the desired size.
The projection distance range at which focusing is possible is 0.8 m (for a 30 model) to 12.9 m (for a 300 model).
Install within this range.

* The figures indicated for “height of screen from projector lens center” on the projection distance table are for a
lens shift of 55% V.
[Reading the Table]
From the upper table on this page, to project wide images on a 100 screen, install at about 2.6 m from the front.
Also, from the lower table we can see that about 1.3 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.
The projected image can be moved up and down, left and right using the lens shift function. (
