The +3.3V power provided to pins 19 and 20 of J32 is protected by a software-controllable
power switch (1 Amp max.). This switch is controlled by the L_VDD_EN signal from the LVDS
interface controller in the Intel® 7 Series Platform Controller Hub (PCH). See the
Intel GM45
Datasheet
for detailed information.

Two DisplayPorts are provided using two 20-pin mini DisplayPort connectors at locations J26
and J27. DisplayPort consists of three interfaces; main Link, Auxiliary channel, and Hot Plug
Detect. The main Link transfers high speed isochronous video and audio data. The Auxiliary
channel is used for link management and device control. The EDID is read over this interface.
The Hot Plug Detect signal alerts the PCH when a device is connected.
