Users interested in connecting a laptop with a Mini DisplayPort to their HDTV via a HDMI cable lost one option for doing so last week. HDMI Org, the group that licenses the HDMI specification, has determined that companies selling cables with one Mini DisplayPort male end and one HDMI male end don't conform to the HDMI spec.
Those rules require HDMI cables to have two male HDMI ends. As a result, HDMI is requiring resellers of cables incompatible with the rules to pull those cables from their shelves.
Apple and Toshiba are two laptop manufacturers that use the Mini DisplayPort on their laptops. Users that want to connect one of these laptops to an HDTV do have an option, however. HDMI Org says that adapters that have a male Mini DisplayPort end with a female HDMI end that can be connected to a standard HDMI cable meet their standard. Users can connect the two together between a laptop and HDTV.
