In-Depth Information
• High performance. A true data bandwidth of 8.64Gbps (four lanes at 2.16Gbps per
lane) allows WQXGA 2560×1600 resolution.
• Support for internal (embedded) as well as external LCD connections. This allows a
universal interface for both desktop and laptop systems.
• Optional audio that supports displays with built-in speakers.
• Optional HDCP to allow playing protected media.
• Interoperability with DVI and HDMI over a DisplayPort connector. You can connect
to DVI or HDMI with simple and inexpensive adapters.
•Anauxiliary1Mbpschannel,whichallowsfortwo-waycommunicationforintegrated
cameras, microphones, and so on.
• A powered connector, which powers some LCD displays directly.
• An optional latching connector that uses a simple thumb-press release design with no
bolts or jackscrews.
DisplayPort 1.2 is fully backward compatible with 1.1 and adds the following features:
•Doubletheperformance.DisplayPort1.2offers21.6Gbpsraw(17.28Gbpstrue)band-
width, which is more than twice that of HDMI 1.3a and nearly triple that of DVI.
• Multiple data streams, which allows support for two WQXGA 2560×1600 or four
WUXGA 1920×1200 monitors daisy-chained over a single cable.
• An auxiliary channel speed increase to 480Mbps. This allows USB 2.0 speed connec-
tions for cameras, microphones, or other devices.
• The Mini DisplayPort connector. This connector is approximately half the size yet
provides full functionality for laptops or other devices where space is at a premium.

The DisplayPort connector has 20 pins and is only slightly larger than USB size (15.9mm
vs. 12mm wide). The pins consist of four data lanes (differential pairs), an auxiliary chan-
