8.3.1 [ C01 ] Setting HDCP input
Some source devices check whether the connected device supports HDCP and then those source devices
decide whether they encrypt HDCP signals or not.
Since the VAC is HDCP compliant, if it is connected to a display device that does not support HDCP, video
may not be displayed. In these cases, the problem can be solved by setting this menu to “oFF”.
