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. KEYSTONE 0 Vertical keystone distortion correction Operation Press the H button. Press the I button. NOTE: B 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". (Refer to page 45.) B Vertical 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. B The picture size will also change when correction of keystone distortion is carried out. B The ratio of length and width of an image may become incorrect depending on the amount of the keystone correction. B Keystone distortion of the on-screen display will not be corrected. 36-ENGLISH
