Adjust the projector image. Christie recommends warming the lens before completing these procedures as
focus may change as the lens warms.
Learn how to adjust the image to correct keystone effect.
Keystone effect occurs when you project an image onto the screen at an angle. As a result, the image appears
distorted and resembles a trapezoid.
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. Christie
recommends using 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, adjust the tilt and level of the projector.
When making the adjustments, set the light source to minimum power.
