Adjusting the image
Adjust the projector image. Christie recommends warming the lens before completing these
procedures as focus may change as the lens warms.
Correcting keystone effect
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. 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, adjust the tilt and level of the projector.
When making the adjustments, set the light source to minimum power.
