Report: Mini DisplayPort-to-HDMI Cables Are Illegal

Cables are unable to be tested against HDMI spec, so HDMI Licensing LLC declares them as unlicensed. Apple, Toshiba, HP and Dell all rely heavily on the cable.

The road to convergence between A/V and IT just hit a bump.

According to TechRadar, millions and millions of Mini DisplayPort-to-HDMI cables, sold by manufacturers such as Apple, Toshiba, Dell and HP, are unlicensed and do not meet the HDMI specification.

TechRadar cites HDMI Licensing LLC as saying that since the cable only has one HDMI connector, it does not meet the specification, which calls for connectors on both ends. Therefore, the cable itself cannot be tested to see if it conforms to the HDMI spec.

Cables with one Mini Display connector and a “female” HDMI connector conform to the spec.

TechRadar says that unless HDMI Licensing “bends the spec” to accommodate the manufacturers, the cables could be banned from being sold.

Apple could be the biggest loser since its new Thunderbolt I/O relies heavily on this type of connector.
