DisplayPort Connectors

TM
The Intel® Core processors used on SC2-PRESTO are equipped with an integrated graphics
controller, which supports DisplayPort and DVI interfaces permitting simultaneous independent
operation of up to three displays. Two DP receptacles are available from the SC2-PRESTO 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 SC2-PRESTO. 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 SC2-PRESTO takes care about this situation. Nevertheless,
before ordering DP cable assemblies, verify the associated wiring diagram.
