DisplayPort 1.0 approved by VESA

The Video Electronics Standards Association, also known as VESA, has approved the DisplayPort 1.0 specification. DisplayPort was created to replace DVI and become a unified interface for computer monitors, TVs, and projectors. Designed to carry a full, uncompressed video stream with the accompanying audio, DisplayPort 1.0 offers up to 10.8 Gbps of bandwidth—more than twice the 4.95 Gbps available with single-link DVI. Unlike DVI, DisplayPort also supports content protection via 128-bit ASE encryption, and it is designed to be expandable to offer greater bandwidth in the future. Finally, VESA says DisplayPort devices can offer "legacy compatibility" with DVI, although it isn't specified whether the DisplayPort standard itself is backwards-compatible with DVI.

Following DisplayPort's formal introduction, VESA members Dell, HP, and Lenovo announced their support for the new interface. Dell CTO Kevin Kettler says DisplayPort can "enable more-affordable flat-panel displays, support protected high-definition content, and scale performance to meet the demands of next-generation displays by enabling new features and usages." Lenovo Senior VP and CTO George He also praised the standard's open nature, touting it as superior to proprietary solutions—likely a jab at HDMI, which requires that royalties be paid for each HDMI-equipped device sold. A timeline for the integration of DisplayPort in the companies' future products was not specified, but the standard is claimed to be "designed to efficiently accommodate" Windows Vista, which will allegedly support higher resolutions and color depths than Windows XP.
