PROJECTOR
The keystone image is created when the
projector image is projected to the screen at
an angle. The keystone correction will restore
the distorted image to a rectangular or square
shape.
ADJUST FOCUS AND KEYSTONE
Adjust the focus by turning the knob while
observing the image near the center of the
screen. Optimal focus is obtained when the
image is visible and sharp. Depending
on the projected screen size, the focus near
the screen edges may be less sharp than the
screen center.
