Screen Size and Projection Distance
The distance between the projector and the screen determines the actual image
size.
While referring to the table below, position the projector so that the image size
is smaller than the screen 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 image size will be reduced when keystone correction is carried out.
Recommended distance 0.9–11.3 m (2.9–37.0 ft.)
