2 Adjust the Image
This section provides information and procedures for adjusting the projector image.
2.1

Correct Keystone Effect

Keystone effect occurs when you project an image onto the screen at an angle and the projector is not centered
on the screen. The image will appear distorted and resemble a trapezoid. This image identifies the different
types of keystone effect:
If the image suffers from slight keystone effect, it can be corrected with electronic cropping.
If the keystone effect is severe, you can unevenly adjust the feet to compensate for projector tilt. It is
recommended that you use lens offset to align the center of the image to the center of the screen before you
correct the keystone effect.
If one side of the image is longer than another, see
2.1.1
