5.26.2.5 Embedded DisplayPort
Embedded DisplayPort (eDP*) is a embedded version of the DisplayPort standard
oriented towards applications such as notebook and All-In-One PCs. eDP is supported
only on Digital Port D. Like DisplayPort, Embedded DisplayPort also consists of a Main
Link, Auxiliary channel, and a optional Hot Plug Detect signal.
The eDP support on desktop PCH is possible because of the addition of the panel power
sequencing pins: L_VDD, L_BKLT_EN and L_BLKT_CTRL. The eDP on the PCH can be
configured for 2 or 4 lanes.
PCH supports Embedded DisplayPort* (eDP*) Standard Version 1.1.
5.26.2.6 DisplayPort Aux Channel
A bi-directional AC coupled AUX channel interface replaces the I2C for EDID read, link
management and device control. I2C-to-Aux bridges are required to connect legacy
display devices.
5.26.2.7 DisplayPort Hot-Plug Detect (HPD)
The PCH supports HPD for Hot-Plug sink events on the HDMI and DisplayPort interface.
5.26.2.8 Integrated Audio over HDMI and DisplayPort
DisplayPort and HDMI interfaces on PCH support audio.
supported audio technologies on the PCH.

PCH will continue to support Silent stream. Silent stream is a integrated audio feature
that enables short audio streams such as system events to be heard over the HDMI and
DisplayPort monitors. PCH supports silent streams over the HDMI and DisplayPort
interfaces at 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz and 192 kHz sampling
rates.
5.26.2.9 Serial Digital Video Out (SDVO)
Serial Digital Video Out (SDVO) supports SDVO-LVDS only on the PCH. Though the
SDVO electrical interface is based on the PCI Express interface, the protocol and
timings are completely unique. The PCH utilizes an external SDVO device to translate
from SDVO protocol and timings to the desired display format and timings.
SDVO is supported only on Digital Port B of the PCH.
