DisplayPort is a digital display interface standard produced by the Video Electronics Standards Association (VESA). The specification defines a royalty-free digital interconnect for audio and video. The interface is primarily used to connect a video source to a display device such as a computer monitor or television set. The first version 1.0 was approved by VESA on May 3, 2006. Two updated revisions have since been approved starting with 1.1a on April 2, 2007 followed by the current standard 1.2 on December 22, 2009.
DisplayPort is designed to replace Digital Visual Interface (DVI) and Video Graphics Array (VGA), as well as replace internal digital LVDS links in computer monitor panels and TV panels. DisplayPort can also provide the same functionality as HDMI but is not expected to displace HDMI in high-definition consumer electronics devices. Most of the DisplayPort supporters are computer companies including Apple, Dell, HP, Lenovo, Fujitsu, Toshiba and Acer, some of which have released several computer monitors that support DisplayPort and some also with HDMI. In December 2010 it was announced that several computer vendors and display makers including Intel, AMD, Dell, Lenovo, Samsung and LG would stop using LVDS from 2013 and legacy DVI and VGA connectors from 2015, replacing them with DisplayPort and HDMI. Likewise, HP expects that DisplayPort will completely displace VGA and DVI by 2013. However, many are still using those connectors, so it doesn't seem to have much effect right now. Most laptops still have HDMI and legacy VGA ports, but not DisplayPort or DVI. In 2010, BenQ launched BL2201PT, BL2201PU, BL2400PT & BL2400PU that support DP 1.1a.
