Mini DisplayPort Connector
DisplayPort consists of three interfaces:

Main Link – transfers high-speed isochronous video and audio data

Auxiliary channel – used for link management and device control; the EDID is read over
this interface

Hot Plug Detect – indicates that a cable is plugged in
The DisplayPort interface supports:

Audio signaling

DP++ mode allowing connection to an HDMI device through a passive adapter.
“Passive” means that the adapter does not require external power (because it uses the DP
port’s 3.3 V power) and it does not require software drivers.
Figure 23 shows the location of the 20-pin Mini DisplayPort connector. Table 13 lists the pinout
of the J3 Mini DisplayPort connector.
