CPU Board

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

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.
