Correcting keystone distortion
Keystone distortion is corrected automatically when the projectors 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.

NOTE:

If 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.)

Vertical keystone distortion can be corrected to
±
30
°
of the angle of tilt. Horizontal
keystone distortion can be corrected to
±
20
°
of the angle of tilt for the PT-LC80E.
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.

The picture size will also change when correction of keystone distortion is carried out.
