Correcting keystone distortion
Keystone distortion is corrected automatically when the projector’s automatic setup function is used, but this correction will not apply if the screen itself is tilted. In such cases, you can correct the keystone distortion manually with the following procedure.
Vertical keystone distortion correction only.

NOTE:
BIf you press the AUTO SETUP button after correcting the keystone distortion manually, the automatic keystone correction function will operate and the corrected picture will return to its previous incorrect condition. To prevent this from happening, you can set “AUTO KEYSTN” in the “OPTION1” menu to “OFF”. (Refer to page 42.)
BVertical keystone distortion can be corrected to ±30° of the angle of tilt. However, the greater the correction amount, the more the picture quality will deteriorate, and the harder it will become to achieve a good level of focus. To obtain the best picture quality, set up the projector and screen in such a way that the amount of keystone correction required is as minimal as possible.
BThe picture size will also change when correction of keystone distortion is carried out.
