DOT CLOCK
(RGB only)
Periodic striped pattern interference
(noise) may occur when a striped
pattern such as the one below is

KEYSTONE
Before carrying out keystone
correction, 1) adjust the forward/back
angle of tilt of the projector by pressing
the adjuster buttons and 2) press the
AUTO SETUP buttons to correct
vertical keystone distortion. (page 27)
The vertical keystone distortion will be
automatically corrected by the
projectors automatic setup function.
However the horizontal distortion needs
to be corrected or a tilted screen needs
to be adjusted manually by following
any of the procedures in the table.
NOTE:

If signals with a dot clock
frequency of 100 MHz or higher
are being input, interference may
not be completely eliminated when
the DOT CLOCK and CLOCK
PHASE adjustments are carried
out.

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. In addition,
if you change the input signal and press
the AUTO SETUP button, the keystone
correction may be cancelled depending
on the type of signal and the angle of tilt
of the projector. To prevent them from
happening, you can set “AUTO
KEYSTONE” in the OPTION menu to
“OFF”

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
