What is DisplayPort?
DisplayPort is a new display connectivity developed to create a digital interface standard that will provide a high-performance feature-rich alternative to DVI and HDMI. DisplayPort is intended to be a successor to VGA. DisplayPort provides support for highresolution displays, digital content protection, and the addition of new features to the standard. It was also designed to be fully
interoperable with current display interfaces while providing enhanced performance in Comparison to VGA.
Why not use DVI or HDMI?
DVI is the digital interface of choice in most modern commercial displays, but it is unsuitable as a VGA replacement for a number of reasons. The connector is large and thumb-screws are not user-friendly. There is a 5 meter limit to cable length. There can be confusion between DVI-A, DVI-I, DVI-D, and DVI-D dual-link cables, and different cables are needed to support different display sizes. There is no support for audio over the DVI cable. Finally, as there is no active Standards body governing DVI, there is no future development or enhancement that can be done.
HDMI is a standard in home audio and video electronics, and it provides audio support and content protection with a small connector. However, it is controlled by a consortium of consumer electronics companies imposing a royalty fee structure that is unacceptable to the computer industry, while DisplayPort does not.
What are the benefits and features of DisplayPort?
• The connecter is smaller and doesn’t require the use of thumb-screws
• Support for cables up to 15 meters long
• 10.8 Gbit/s capacity with planned higher data rates available through future updates
• Support for audio and other data types
• Digital content protection (HDCP) (HP provides HDCP support on all shipping DisplayPort outputs.)
• 30-bit color capability
• High resolutions including support for 30” diagonal displays with a single cable
• Extensibility for addition of future performance benefits and features
• Interoperability with VGA, DVI, and HDMI
