The HDMI/DVI mode, the color space selection, the color range conversion, the PCM
subsampling, and the HDCP handling are set to automatic.
7.6.5. Set HDMI output port parameters
Description: HDMI output cards have various settings, which can be set with this command.
Every setting has an automatic mode (this is the default) when the system selects the
proper conversions based on the type of the video signal and the capabilities of the sink
device, but you are also able to force other conversions with this command.
If you send the first version of the command (with @SO) then the new settings will affect
only the <out> output port. The @AO version will affect all HDMI output ports regardless of
the value of the <out> field.
