1. The Hot Plug Detect (HPD) signal is driven by an HDMI sink and asserted when the HDMI cable is connected to
notify the HDMI source of the presence of an HDMI sink. In most cases, the HDMI sink is simply connected to 5V
power signal. Therefore, in the PCB, if you choose to use a voltage divider or level shifter, the HPD polarity remains
as Active High. However, if you add an inverter to the HPD signal, then the HPD polarity must be set to Active Low
in HDMI Transmitter Subsystem GUI.
