Screen size and projection distance
Determines the distance that the screen must be from the lens in order to obtain the required
screen size.
The projector’s Standard Lens is approximately a 1.3x zoom lens and the largest screen size is
about 1.3 times the size of the smallest screen.
Using the following table for reference purposes, install the projector so that the screen size is
smaller than the screen.
Point
· The projection distances listed above are the distances when the standard lens is in use.
If optional lenses are to be used, refer to the relevant instruction manuals for further
details.
· The screen will become smaller when the keystone correction function is used.
