Apple hopes to boost adoption of the Mini DisplayPort video port built into its 24in LED Cinema Display by licensing it for free to companies that want to support it.

DisplayPort is an emerging video standard promoted by the Video Electronics Standards Association (VESA). Developed to replace Digital Visual Interface (DVI) and eventually to replace the ubiquitous analog VGA interface found on PCs, DisplayPort offers greater bandwidth, enabling users to run a 30in screen, for example.

With the refreshed MacBook, MacBook Air and MacBook Pro models, Apple jumped to the bleeding edge of DisplayPort support, introducing the LED Cinema Display. The Mini DisplayPort Connector fully supports the VESA DisplayPort protocol, but uses a fraction of the space - hence its introduction with refreshed Apple laptops.

Apple is offering a license to "develop or distribute plugs, receptacles or other devices implementing the Mini DisplayPort Connector" to interested parties; a web page on the Apple Developer Connection describes the connector and offers links to the evaluation licence and other useful information
