8) Setting the clamp position
Simultaneous input of RGB (G ON SYNC) signals and sync signals may produce brightness inappropriately, resulting
in an overly bright screen or images with a greenish cast. If this occurs, select CLAMP POSITION: LOCKED.
Normally, the setting may be left on CLAMP POSITION: AUTO.
Methods for generating clamp pulse (a timing pulse necessary for reproducing brightness) are shown in Figure 1, a
and b.

the SET button to change the setting.
Each time the SET button is pressed, the setting
will change between AUTO and LOCKED.

(NOTE) Cannot be set during component picture signal input.
With CLAMP POSITION: AUTO, separate sync signals will be monitored. The method shown in Figure 1, “a,” will
automatically be applied when separate sync signals are judged as present, and the method in Figure 1, “b,” will be
applied when they are judged as not present. However, as shown in Figure 2, if separate sync signals are input
simultaneously with G ON SYNC, the former will be judged as present, and clamp pulse wll be generated using the
method shown in Figure 1, ”a.” This will result in incorrect clamp timing, preventing brightness from being produced
normally.
If this occurs, either do not connect the separate sync signals or select CLAMP POSITION: LOCKED. If CLAMP POSITION:
LOCKED is selected, the clamp pulse wil be reproduced using the method in Figure 1, ”b,” whether or not separate
sync signals are present. This will make it possible to produce brightness correctly.
(NOTE) The figures above are for illustrative purposes only.
(NOTE) Composite sync input may be considered to be the same as separate sync input.
