DOT CLOCK
(PC only)
Periodic striped pattern interference (noise) may occur when a striped pattern such as the one below is projected. If this happens, press the
Ior H button to adjust so that any such noise is minimised.
CLOCK PHASE
(PC/YPBPR only)
Adjust the “DOT CLOCK” setting first before carrying out this adjustment. Press the I or H button to adjust so that the noise level is least noticeable.

ON
When WSS (Wide Screen Signalling) is detected from PAL or 625i(576i) YPBPR signals, the aspect ratio will also be switched automatically.
OFF
WSS will not be detected from PAL or 625i(576i) YPBPR signals.

NOTE:
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.
BThe ratio of length and width of an image may become incorrect depending on the amount of the keystone correction.
