Masking The Screen Edges - Christie CP2309-RGB User Manual

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.
3. If one side of the image is longer than another, adjust the tilt and level of the projector.

Typically, you install top and side masking to allow a greater range of adjustment.
