HDMI Licensing, the administrator of the High-Definition Multimedia Interface HDMI spec, has decided that the time has come to do away with dongles and given the thumb's up to USB-C.
The HDMI cable will utilize the USB Type-C connector on the source side and any HDMI connector on the display side, HDMI licensing says.
Unlike the other Alt Mode display technologies which require various adapters or dongles to connect to HDMI displays, HDMI Alt Mode enables an easy connection via a simple USB Type-C to HDMI cable.
Only one side of this cable can be reversed.
So good luck with that
HDMI Licensing says it's made the decision to hook up with USB-C because gazillions of devices will use it any month now, so it makes sense to give the people what they want and just let their new kit plug straight into tellies and monitors rather than making them pfaff about with dongles.
