DisplayPort

DisplayPort

(1) (display port) Generically, a socket that is cabled to a monitor. Examples are VGA, DVI and DisplayPort (definition #2 below). See VGA and DVI.

(2) (DisplayPort) A VESA standard digital interface between a computer and a monitor (www.vesa.org). DisplayPort uses a small connector and thin cable that extends to 50 feet. First deployed in 2008, DisplayPort gained traction on PCs, but Mini DisplayPort and its Thunderbolt variation have been the main display interfaces on the Mac. See Thunderbolt.

DisplayPort is also used in laptops and TVs. An Embedded DisplayPort (eDP) connects the motherboard to the LCD screen in a laptop, and the digital TV counterpart is the Internal DisplayPort (IDP).

Packets and More Efficient
Unlike other monitor interfaces, DisplayPort transmits packets, each of which contains its own clock synchronization. The packet architecture enables DisplayPort to be enhanced much more easily than an interface where each physical pin is dedicated to some purpose. In addition, DisplayPort allows for slimmer screens, because its Direct Drive interface eliminates circuits that would otherwise be in the monitor.

Copy Protection
DisplayPort supports HDMI's HDCP copy protection and optionally the DisplayPort Content Protection (DPCP) scheme, which is similar. See HDCP.

Multiple Channels
DisplayPort (DP) supports multiple independent data streams and can drive up to six monitors daisy chained together (see MST). Also included is an auxiliary channel for device control and management. In Version 1.2 (2010), the auxiliary channel increased from 1 to 720 Mbps to enable video transfer along with USB 2.0 data. See Thunderbolt and SlimPort.

Support for Non-DisplayPort Displays
With passive cables, "dual-mode" DP (++ logo) connects to TVs via HDMI and to monitors via single-link DVI. VGA and dual-link DVI monitors require active adapters. See VGA, DVI and HDMI.
