processors used on PC5-LARGO are equipped with an integrated graphics controller,
which supports DisplayPort interfaces permitting simultaneous independent operation of up to three
displays. Two DP receptacles are available from the PC5-LARGO front panel, as mDP (Mini DisplayPort)
connectors, which is a space saving alternate to the standard DP connector and is also specified by the
VESA.

+3.3V via 0.5A current-limited electronic power switch. This voltage is switched on in S0 state only.
Most DisplayPort monitors come with the standard DP connector, hence requiring a mDP to DP cable
assembly for use with the PC5-LARGO. For attachment of either a classic style analog RGB monitor,
DVI or HDMI type display to the P-DP1/2 receptacles, there are both adapters and also adapter cables
available.
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 should not connect the pins 20 of both cable ends, in order to
avoid a back driving conflict. Fortunately the PC5-LARGO takes care about this situation. Nevertheless,
before ordering DP cable assemblies, EKF recommends to verify the associated wiring diagram.
