DisplayPort — The Replacement Connector For VGA

Learn Why Technology Is Moving Away From VGA to DisplayPort

DisplayPort is a digital display interface standard developed by the Video Electronics Standards Association (VESA) designed to facilitate the transfer of video, audio and data, between a source and sink device. DisplayPort 1.2 is capable of emitting HDMI or DVI-D TMDS signals through the use of a simple passive converter. DisplayPort has been HDCP compliant since the DP1.1 standard.1

The DisplayPort 1.2a standard was released in January of 2013 and includes support for Multi-Stream Transport (MST), Ultra HD resolutions and many more performance enhancements.

DisplayPort is replacing VGA connectivity on most computers because of its rich feature set, its compatibility with CMOS fabrication techniques and its compatibility with HDMI and HDCP technologies. DisplayPort was included in about 1-in-20 desktops and 1-in-50 laptops as of 2009. DisplayPort use is expected to be included in 19-of-20, or 95%, of all computers by 2014 as the industry continues to phase out LVDS. Much of this exponential growth in DisplayPort++ deployment is expected to occur in 2014 and 2015.2

While the three major vendors of central and graphics processing units—Intel Corp., AMD Inc. and nVidia—have moved to integrate DisplayPort into their current products, this doesn't signal a competition between DisplayPort and HDMI as A/V connectivity standards. Both interfaces will serve distinct markets.3

The DisplayPort standard defines an HDMI "compatibility mode," identified by the DP++ logo that allows devices so equipped to seamlessly switch to an HDMI output format when a passive adapter is connected. This ensures that computers and devices leveraging a DisplayPort connection remain compatible with the very large installed base of HDMI-enabled devices.4

According to International Data Corporation (IDC) analysis, DisplayPort market penetration will experience a compounded annual growth rate of 106% between 2009 and 2014. The firm, 'Research and Markets' stated in its "Global HDMI and DisplayPort-enabled Equipment Market 2012-2016" report that DisplayPort Multi-Mode market penetration would grow at a combined annualized growth rate (CAGR) of 31.6% over the four year period covered by the report. DisplayPort is quickly becoming a key technology of the A/V market, with no end to its growth in sight.
