Adjustment of the Clock Frequency/Clock Phase
(AUTO PICTURE)
When AUTO PICTURE is set to ON, normally the clock
frequency adjustment and the clock phase adjustment are not
necessary, but this adjustment should be made when the au-
tomatic adjustment cannot be made correctly.
Make the adjustment when a new signal has been input, when
vertical lines appear blurry, or if the image appears unclear.
H-POSITION 1,2 and V-POSITION 1,2 are not available at
the time of RGB input when AUTO PICTURE is turned on.
To adjust H-POSITION 1,2 and V-POSITION 1,2 at the
time of RGB input, turn off AUTO PICTURE.
