Almost a year after approving the original DisplayPort 1.0 specification, the Video Electronics Standards Association has approved the new DisplayPort 1.1 spec. First proposed by the DisplayPort Task Group late last year, DisplayPort 1.1 adds support for version 1.3 of the High-bandwidth Digital Content Protection (HDCP) copy protection standard. This addition will allow DisplayPort 1.1-compatible systems to display copy-protected Blu-ray and HD DVD movies at their full resolution on monitors with DisplayPort interfaces.
According to VESA, DisplayPort 1.1 is designed to replace LVDS, DVI, and eventually VGA as the standard connection for both internal and external displays. The DisplayPort standard also provides 10.8Gbps (1.35GB/s) of bandwidth, giving it an edge over 9.9Gbps dual-link DVI outputs. Last, but not least, the DisplayPort specification is open and free to use. By contrast, companies that use HDMI must pay royalties for each HDMI-equipped device they sell. The DisplayPort 1.1 spec can be downloaded here (registration required).
