port on the Master Controller or the IR Extender/IR Connecting Block of the 3rd party control
system.

HPD Control
Hot Plug Detection (HPD) may be forced in order to provide the connected input/source with
the necessary voltage to inform the device that an output/display is connected and active.
In cases of many layers of connectivity, HPD may be lost leading to no signal at the display.
In those cases, forcing the HPD mode on will keep an active signal on at all times. The Key
Digital IR Remote is required to change the HPD mode of the KD-S2x1/KD-S4x1 unit.
