Follow the pictures below to adjust the focus and trap-
ezoidal screen. 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.
Keystone image is created when the projector beam is
projected to the screen in an angle. Keystone correc-
tion will restore the distorted image to a rectangular or
square shape.
