Specified by the VESA DisplayPort connector standard is a dedicated power pin 20 (+3.3V 0.5A). Both
the GPU (source side) and a DP monitor (sink side) must provide power via this pin. A VESA specified
standard DisplayPort cable however must not connect the pins 20 of both cable ends, in order to
avoid a back driving conflict. Unfortunately there are cable assemblies available with pin 20 passed
through, with unpredictable results on the system behaviour. Before ordering DP cable assemblies,
verify the associated wiring diagram.
