Screen Size and Projection Distance

The distance from the lens to the screen determines the actual image size.
Recommended distance
While referring to the following table, position the projector so that the
images are projected onto the screen at the optimum size. The values
should be used as a guide for setting up the projector. The actual values
will vary depending on projection conditions and the zoom setting.

* When installing against a wall, leave a space of 20 cm (7.9 in.) or more
between the projector and the wall.
TIP
• The standard lens allows a zoom ratio of up to about 1.6. The image
size at the maximum zoom setting is about 1.6 times bigger than the
image size at the minimum zoom setting.
• When keystone correction is carried out, the projected images will
become smaller. Use the zoom function to adjust the size of the
sp.40
images if necessary.
