HDMI MHL is a protocol for Mobile High-definition Link, and it’s the brainchild of a group of companies—including Nokia, Samsung, Silicon Image, Sony and Toshiba—that wanted a specification that could be used to connect smart phones, tablets, and other devices to an HDTV.

MHL provides for 1920×1080 and 7.1 Dolby audio over the HDMI cable.

Cables for mobile phones are readily available which can be connected to the HDTV which allow them to be a media source.

MHL enabled televisions are now increasingly available making them a standard feature so that it motivates more and more consumers to take advantage.
