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 OPTION
menu to “OFF”.
• Keystone distortion can be corrected to ±30° of the angle of tilt for the
projector. However, the greater the correction amount, the more the
picture quality will deteriorate, and the harder it wili 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.
