If
you are projecting from a table or other flat surface, and the
image is too high or low, you can adjust the image height using the
projector's adjustable feet.
Turn on the projector and display an image.
If the image is tilted, rotate the front feet to adjust their
height.
Use the vertical and horizontal lens shift dials on the
projector to adjust the position of the projected image as
necessary.
If the projected image is unevenly rectangular, you need to
adjust the image shape.
