Screen Size and Projection Distance

The distance between the projector's lens and the screen determines the 
actual image size.

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 about 20 cm (7.9 in.) 

between the projector and the wall.

TIP

• The projector's lens allows a zoom ratio of up to about 1.2. The 

image size at the maximum zoom setting is about 1.2 times bigger 
than the image size at the minimum zoom setting.

• The image size will be reduced when keystone correction is carried 

out.
