As the consumer electronics industry moves toward high definition video content, we must also remember the upgrades that PC equipment will receive, which inevitably means there is room for a new display interconnect standard. High-definition Multimedia Interface (HDMI) provides higher bandwidth than the Digital Video Interface (DVI) and also support for audio content.
The Video Electronic Standards Association (VESA) is promoting its own display interconnect called DisplayPort. Video-wise, it can match what HDMI boasts about, and also supports the studio-backed High-bandwidth Digital Content Protection (HDCP) and also has its own optional DisplayPort Content Protection (DPCP).
Like DVI however, DisplayPort does not support audio content. VESA however, would not see this as a problem since it didn't hinder DVI's performance in the market. On Monday, the group behind HDMI announced that more than 50 Desktops, Notebooks, Motherboards and Graphics cards are shipping with the HDMI technology on-board, sending a message to VESA that it plans to fight to become the standard.
DisplayPort has many advantages over HDMI however and is very powerful. It performs with relatively low power-consumption, has a low pin count and can transmit data at 10.8 Gigabits/second, supporting resolutions up to 2560x1600 (WQXGA) and possibly beyond. It can perform properly over a length of cable up to 15 meters in length, which many see as a great advantage over HDMI.
