To reduce image distortion, it is recommended that the center of the projector
lens be as close to the center of the screen as possible.
KEYSTONE CORRECTION KNOB
Adjust the focus by turning the
knob while observing the image
pixels near the center of the
screen. Optimal focus is
obtained when the pixels are
clearly visible. Depending on
the projected screen size, the
focus near the screen edges
may be less sharp than the
screen center.
Then sharpen the image
by rotating the focus knob.
Keystone image is created
when the projector beam is
projected to the screen in an
angle. Keystone correction will
restore the distorted image to a
rectangular or square shape.
