Integrated Graphics Display
The Graphics Processing Unit’s display pipe can be broken down into three
components:
components:
• Display Planes
• Display Pipes
• DisplayPort and Intel FDI

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 hardware 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.
