A number of leading computer and display manufacturers have announced plans to promote the use of DisplayPort, High-Definition Multimedia Interface (HDMI), and other scalable and lower power digital interfaces in computers.

Advanced Micro Devices (AMD), Dell, Intel Corporation, Lenovo, Samsung Electronics LCD Business and LG Display have announced various timetables for the phaseout of the older interfaces such as VGA and the low voltage differential signaling technology (LVDS) panel interface.

Intel and AMD said their product lines will have all-digital interfaces by 2015.

"Legacy interfaces such as VGA, DVI and LVDS have not kept pace (with the evolution of display standards), and newer standards such as DisplayPort and HDMI clearly provide the best connectivity options moving forward," said Eric Demers, AMD�s chief technology officer, Graphics Division. He believes that DisplayPort 1.2 will become the future interface for PC monitors, while HDMI 1.4a will become the same for TVs.

Samsung Electronics LCD Business has been embedding DisplayPort in notebooks since March 2010 while LG Display is now manufacturing LCD panels with Embedded DisplayPort.
