Many new devices are using Mobile High-Definition Link ports (MHL) to output video to a compatible HDMI port on a TV or monitor. MHL is an industry standard that adds video output through the existing microUSB port. Unfortunately for owners of a Samsung Galaxy S III, Samsung has changed the configuration of their MHL port slightly and it now requires a special MHL adapter cable rather than the standard MHL cables that are commonly available.
Apparently, Samsung changed some pinouts in their MHL configuration, possibly for supporting future accessories or for some other currently unknown improvement. At least we’re hoping that’s the reason rather than Sammy trying to make more money by selling special adapters (which would be a very Apple-esque move).
In any case, if you plan on getting an S III and want the ability to output video, you’ll need to plunk down an extra $30 for their custom adapter.
Check out videos of the S III and its MHL adapter after the break.
