There have been 2 connectors used on phones so far and this MHL cable is integrated with 5 pins connector that suit for majority of the Smartphones except Samsung Galaxy S3 and Note 2. 5-pin MHL-USB Connector The first implementations use the most popular mobile connection (micro USB) and the most popular HDTV connection (HDMI). Other than the physical connectors, no USB nor HDMI technology is being used. It is exclusively MHL signalling through the connectors and over the cable. 11-pin MHL-USB Connector The Samsung Galaxy S III and Galaxy Note 2 use a connector that is similar to the original 5-pin MHL-USB connector, but it uses 11-pins in order to achieve a few functional improvements over the 5-pin design. It supports the use of USB and MHL simultaneously. (Note that the new Samsung 11-pin MHL-HDMI adapter also has a USB On-The-Go port). Samsung’s Galaxy S3/ Note 2 can power the MHL-HDMI adapter (when used with a non-MHL-compatible-TV). Although this can theoretically also be done with the standard 5-pin micro-USB connector, the Galaxy S III's 11-pin connector is believed to be the first smartphone that supports this functionality.
