You
can use the projector's keystone correction buttons to correct the
shape of an image that is unevenly rectangular on the sides.
Note: To
provide the best possible image quality, adjust the projector's
position to correct the image shape. If this isn't possible, use
the keystone correction buttons on the projector to correct the
image shape.
Note: To use
the keystone correction feature, you must first set the lens to the
center-top position using the lens shift dials.
Note: Wait 30
minutes after turning on the projector before setting the focus for
maximum accuracy.
