Interfaces
Display is the presentation stage of graphics. This involves:
• Pulling rendered data from memory
• Converting raw data into pixels
• Blending surfaces into a frame
• Organizing pixels into frames
• Optionally scaling the image to the desired size
• Re-timing data for the intended target
• Formatting data according to the port output standard
2.5.4 DisplayPort*
The DisplayPort* is a digital communication interface that uses differential signaling to
achieve a high-bandwidth bus interface designed to support connections between PCs
and monitors, projectors, and TV displays.
A DisplayPort* consists of a Main Link, Auxiliary channel, and a Hot-Plug Detect signal.
The Main Link is a unidirectional, high-bandwidth, and low-latency channel used for
transport of isochronous data streams such as uncompressed video and audio. The
