9-1. 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 0.78 m to 12.89 m. 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 60% V.
Reading the Table
From the upper table on this page, to project wide images on a 150 screen, install at about 4.0 m
from the front.
Also, from the lower table we can see that about 2.2 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. (→ page 23)
