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, rotate the front foot to extend
or retract it.
If the image is tilted, rotate the rear feet to adjust their
height.
If the projected image is unevenly rectangular, you need to
adjust the image shape.
