The HDTV Universal Adapter (11pin) supports HD signals up to 1080p. Connect directly to your MHL-enabled mobile phone with an 11-pin Micro USB input to create an HDMI docking station. Then, connect a standard HDMI cable for easy connectivity to home theater or monitor. In order to function, the Adapter also needs to be connected to a power source via the Micro USB port on the adapter itself. (HDMI Cable and Micro USB Travel Charger sold separately)
