for PC monitors. It can be used to check HDCP-compliant
copyright protection functions and to make simple checks on
the DDC function.
Sync signal outputs

or binary), HD, and VD signals.
Analog audio output
The frequency (400 Hz or 1 kHz) can be set and the output
can be turned off separately for left and right channels.
