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.
Vertical

Operation
Press the HHbutton. Press the IIbutton.

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 44.)
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.
Vertical keystone distortion correction only.
