The 1 Meter
DisplayPort Cable defines a new royalty-free, digital audio/video interconnect, intended to be used primarily between a computer and its display monitor, or a computer and a home-theater system. The first version was approved in May 2006, while the current version (1.1a) was approved on January 11, 2008. DisplayPort currently supports a maximum of 8.64 Gbit/s data rate over a 2 meter cable. The video signal is not compatible with
DVI or HDMI, but a DisplayPort connector can pass these signals through. While DVI and
HDMI require separate clock signals, DisplayPort embeds the clock in the data signal. DisplayPort delivers high performance digital connectivity for virtually any use at home or at work. It’s the future standard and it’s available today.
DVI, or Digital Video Interface Technology came about in 1999 as a result of the formation of the Digital Display Working Group (DDWG) a year prior. Their original mission was to create a standard digital video interface for communication between a Personal Computer and a VGA monitor. Recently, however, the consumer electronics industry began implementing DVD players, set-top boxes, televisions, and LCD/plasma monitors with DVI technology.
HDMI (High-Definition Multimedia Interface) is a compact audio/video interface for transmitting uncompressed digital data. It represents a digital alternative to consumer analog standards such as Radio Frequency (RF) coaxial cable, composite video, S-Video, SCART, component video, D-Terminal, and VGA. HDMI connects digital audio/video sources such as set-top boxes, Blu-ray Disc players, personal computers (PCs), video game consoles, and AV receivers to compatible digital audio devices, computer monitors, and digital televisions. HDMI supports, on a single cable, any TV or PC video format, including standard, enhanced, and high-definition video, up to 8 channels of digital audio, and the Consumer Electronics Control signal. It is independent of the various digital television standards such as ATSC and DVB as these are encapsulations of compressed MPEG video streams (which can be decoded and output as an uncompressed video stream on HDMI). A Digital Visual Interface (DVI) signal is electrically compatible with an HDMI video signal; no signal conversion needs to take place when an adapter is used, and consequently no loss in video quality occurs.
DisplayPort is a digital display interface standard put forth by the Video Electronics Standards Association (VESA) since 2006. It defines a new royalty-free, digital audio/video interconnect, intended to be used primarily between a computer and its display monitor, or a computer and a home-theater system.DisplayPort currently supports a maximum of 8.64 Gbit/s data rate over a 2 meter cable. DisplayPort is a competitor to the HDMI connector (with HDCP copy-protection), the de facto standard digital connection for high-definition consumer electronics devices. Another competitor was Unified Display Interface, a low cost compatible alternative to HDMI and DVI. However, the main supporter of UDI, Intel Corporation, has stopped the development of the technology and now supports DisplayPort.
