Adjust the Height

There are four adjustment screws on the bottom of the projector. These
adjustment screws change the image height and projection angle. They
can lift the projection angle by up to 15 degrees. To adjust the projector,
you can screw the height adjustments to fine-tune the projection angle.
If the screen and the projector are not perpendicular to each other, the
projected image becomes vertical trapezoidal. To correct this problem,
adjust the value of Keystone in the Installation menu. See page 27 for more
information.
