Displayport Technical Information and Instructional Video

A lot of Displays such as HP and Dell Monitors already adapted to the displayport standard.

DisplayPort is a digital video and audio connection standard designed by the Video Electronics Standards Association (VESA). It is a royalty-free technology designed primarily for the computer industry but also compatible for home theater application. The format supports both digital video and audio using a single cable.

DisplayPort was primarily designed as a replacement for VGA, DVI and LVDS which are common interfaces used in the computer / IT industries, while HDMI was developed by the Consumer Electronics Industry specifically for Home Theater applications. Toward this end, DisplayPort has certain enhanced features such as direct drive monitor design and single cable multi-function monitor connectivity. Some advantages of HDMI are the ability to support xvYCC color, Dolby TrueHD and CEC (Consumer Electronics Control) signals.

Though both share powerfull A/V features, DisplayPort was designed to complement HDMI, not to replace it.
