Screen Size and Projection Distance

The distance from the lens to the screen determines the actual image size.
The recommended distance and projection distance values given below are
for when the projector is fitted with a standard lens. If the projector has
been fitted with an optional lens, refer to the documentation provided with
the lens.
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.
