PCH Display Interfaces and Intel^® Flexible Display
Interconnect
Display is divided between processor and PCH. The processor houses memory
interface, display planes, and pipes while PCH has transcoder and display interface or
ports. Intel® FDI connects the processor and PCH display engine. The number of
planes, pipes, and transcoders decide the number of simultaneous and concurrent
display devices that can be driven on a platform.
The PCH integrates one Analog, LVDS (mobile only) and three Digital Ports B, C, and D.
Each Digital Port can transmit data according to one or more protocols. Digital Port B,
C, and D can be configured to drive natively HDMI, DisplayPort, or DVI. Digital Port B
also supports Serial Digital Video Out (SDVO) that converts one protocol to another.
Digital Port D can be configured to drive natively Embedded DisplayPort (eDP). Each
display port has control signals that may be used to control, configure and/or
determine the capabilities of an external device.
The PCH’s Analog Port uses an integrated 340.4 MHz RAMDAC that can directly drive a
standard progressive scan analog monitor up to a resolution of 2048x1536 pixels with
32-bit color at 75 Hz.
The PCH SDVO port (configured through Digital Port B) is capable of driving a 200 MP/s
(Megapixels/second) rate.
Each digital port is capable of driving resolutions up to 2560x1600 at 60 Hz through
DisplayPort and 1920x1200 at 60 Hz using HDMI or DVI (with reduced blanking).
5.26.1 Analog Display Interface Characteristics
The Analog Port provides a RGB signal output along with a HSYNC and VSYNC signal.
There is an associated Display Data Channel (DDC) signal pair that is implemented
using GPIO pins dedicated to the Analog Port. The intended target device is for a moni-
tor with a VGA connector. Display devices such as LCD panels with analog inputs may
work satisfactory but no functionality added to the signals to enhance that capability.
