MHL (Mobile High-Definition Link) is a standard used primarily by tablets and smartphones to
provide HDMI connectivity through a smaller micro USB port. It sends the audio and video
signals through the micro USB connector and converts it to a HDMI signal for use on supported
devices, such Vuzix eyewear equipped with a HDMI compatible Controller. The signal remains
in digital format throughout the conversion process, avoiding quality is lost.
A Micro USB to HDMI MHL Adapter enables MHL device, such as an HTC EVO 3D or
Samsung Galaxy S3, to connect to HDMI enabled eyewear models for audio and all of the
HDMI supported video resolutions. It also supports 3D video and HDCP media protection
when used with HDMI enabled Vuzix eyewear models.
Many MHL devices require an external power source to drive the adapter and to power the
eyewear. In many cases this power requirement exceeded the output of typical USB ports on a
computer. Though connecting to a computers USB will charge the eyewear Controller’s battery if
the eyewear is not in use, it may not provide sufficient power for indefinite use. For the shortest
charge time and to enable indefinite use of an MHL connected eyewear session, supply power to
the MHL Adapter from the power adapter provided with your eyewear, with no other USB
devices connected.
