Clamp Timing
According to the signal, this function sets the detection position (i.e., clamp position) of the black level reproduction of the analog
input signal. Normally this is not used.
Mode 0-4 ..... Select the appropriate one.
Adjust .......... This permits the video clamp position for each signal to be set. Use "Adjust" when a clamp timing error occurs at the time of special analog signal reception such as 1080P. Note that "Adjust" is not valid for doubler signals such as NTSC
and PAL.
