2.4.2.1
Display Planes
A display plane is a single displayed surface in memory and contains one image
(desktop, cursor, overlay). It is the portion of the display HW logic that defines the
format and location of a rectangular region of memory that can be displayed on display
output device and delivers that data to a display pipe. This is clocked by the Core
Display Clock.
2.4.2.1.1
Planes A and B
Planes A and B are the main display planes and are associated with Pipes A and B
respectively. The two display pipes are independent, allowing for support of two
independent display streams. They are both double-buffered, which minimizes latency
and improves visual quality.
2.4.2.1.2
Sprite A and B
Sprite A and Sprite B are planes optimized for video decode, and are associated with
Planes A and B respectively. Sprite A and B are also double-buffered.
2.4.2.1.3
Cursors A and B
Cursors A and B are small, fixed-sized planes dedicated for mouse cursor acceleration,
and are associated with Planes A and B respectively. These planes support resolutions
up to 256 x 256 each.
2.4.2.1.4
VGA
Used for boot, safe mode, legacy games, etc. Can be changed by an application without
OS/driver notification, due to legacy requirements.
2.4.2.2
Display Pipes
The display pipe blends and synchronizes pixel data received from one or more display
planes and adds the timing of the display output device upon which the image is
displayed. This is clocked by the Display Reference clock inputs.
The display pipes A and B operate independently of each other at the rate of 1 pixel per
clock. They can attach to any of the DisplayPorts. Each pipe sends display data to the
PCH over the Intel Flexible Display Interface (Intel FDI).
2.4.2.3
Display Ports
The display ports consist of output logic and pins that transmit the display data to the
associated encoding logic and send the data to the display device (i.e., LVDS, HDMI,
DVI, SDVO, etc.). All display interfaces connecting external displays are now
repartitioned and driven from the PCH with the exception of the eDP DisplayPort.
2.4.2.4
Embedded DisplayPort (eDP)
The DisplayPort abbreviated as DP (different than the generic term display port)
specification is a VESA standard. DisplayPort consolidates internal and external
connection methods to reduce device complexity, support cross industry applications,
and provide performance scalability. The integrated graphics supports an embedded
DisplayPort (eDP) interface for display devices that are integrated into the system
(e.g., laptop LCD panel). All other display interfaces connecting to the LVDS or external
panels are driven from the
PCH.
