automatically when the matrix is connected to 1080P display and can be
set to ON/OFF by API commands.
Each HDMI output has a S/PDIF audio breakout, and supports formats up
to 5.1 CH compressed and 2 CH PCM audio.
Supports smart EDID, each input can be assigned to smart EDID mode.
Supports EDID presets, EDID copy and EDID write. By default, each input
EDID is set as 4K@60 4:4:4 HDR with 5.1 CH encoded audio.
