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.
To adjust the image height, or the projector's horizontal and
vertical tilt, rotate the front or rear feet to extend or retract
them.
If the projected image is unevenly rectangular, you need to
adjust the image shape.
