Adjustments and settings
NOTE:
BIf signals with a dot clock
frequency of 108 MHz or
higher are being input,
interference may not be
completely eliminated when
the “DOT CLOCK” and
“CLOCK PHASE” adjustments
are carried out.
DOT CLOCK
(RGB only)
Periodic striped pattern interference
(noise) may occur when a striped
pattern such as the one below is
projected. If this happens, press the
I or H button to adjust so that any
such noise is minimised.
CLOCK PHASE
(RGB/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.
KEYSTONE
If the projected image contains
keystone distortion, follow the
procedures in the table to correct
any keystone distortion.

B
The greater the correction of
keystone distortion 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 range of keystone correction
varies depending on the type of
signal being input (including when
no signal is being input). If you
make an adjustment that is outside
the allowable range, the setting will
not be changed. In addition, if the
input signal is changed after
keystone correction has been
carried out, the correction setting
may be cancelled. This indicates
