Plugging in RGB (G ON SYNC) signals and a sync signal simultaneously may produce inappropriate intensity reproduction, with an
Clamp pulse (a timing pulse necessary for intensity reproduction), is generated in two ways, “a” and “b”, as shown in Figure 1.

Clamp pulse
Sync signals are monitored in “CLAMP : MODE 1”, and the unit is automatically switched to generate a clamp pulse by method “a“ shown in Figure 1 in the presence of sync signal, and by method “b“ in the absence of a sync signal. But when a sync signal is fed simultaneously with G ON SYNC, the unit perceives a sync signal, and generates a clamp pulse as shown in “a“ in Figure 1. The generated clamp pulse is
In this case, unplug the sync signal or set “CLAMP : MODE 2“.
In “CLAMP MODE 2“, the clamp pulse is generated by pulse“b“in Figure 1, whether or not a sync signal is present, ensuring correct reproduction of intensity.
