2). HPD_SINK Pull down resistance.
HPD_SINK have a 5V tolerant structure shown in Figure 9.It needs some drive current to pull down HPD_SINK "H" to "L".
So to pull down HPD_SINK, please use 10kΩ(or under 10kΩ) resistor.
3). About don’t use terminal.
3-1. Unused TMDS input channel recommend open.
3-2. Unused DDC Buffers of R side recommend to pull up to Vcc.
