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 1.2x zoom lens and the largest screen size is
about 1.2 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 screen size will become smaller when the trapezoid correction function is used.
· Install the projector at least 20cm away from the wall
.
