Core Functionality:
- Mobile Device to TV Connectivity: The primary purpose is to mirror the screen of your MHL-compatible mobile device onto a larger display. This allows you to watch videos, browse photos, play games, or give presentations from your phone/tablet on a TV.
- Video Output:
- Most MHL to HDMI adapters support Full HD 1080p (1920×1080) resolution.
- It typically handles a bandwidth of 25-75MHz (or higher for MHL 3.0).
- Audio Output: Supports digital multi-channel audio, often up to 7.1 surround sound (e.g., 192 KHz).
- Simultaneous Charging: A critical feature. These adapters usually have an additional Micro USB (female) port where you connect your mobile device’s charger. This allows your phone/tablet to charge while it’s connected and displaying content, preventing battery drain during extended use.
- Remote Control Protocol (RCP) Support: This feature enables you to control your connected MHL device (e.g., play, pause, navigate menus) using your HDTV’s remote control. This functionality relies on the TV supporting CEC (Consumer Electronics Control), which is a common HDMI feature often branded differently by TV manufacturers (e.g., Anynet+, Bravia Sync).
Connectivity & Compatibility:
- Input (from Mobile Device):
- Micro USB Male (5-pin): This is the standard MHL connector found on most MHL-enabled Android phones and tablets from various manufacturers (e.g., HTC, Sony, LG, older Samsung models).
- Micro USB Male (11-pin): Some Samsung Galaxy devices (like the S3, S4, S5, Note 2, Note 3, etc.) use a proprietary 11-pin Micro USB connector for MHL. Many “2-in-1” adapters include a specific tip or adapter for these 11-pin devices, making them universally compatible.
- Output (to Display):
- HDMI Female: You connect a standard HDMI cable (male-to-male, usually not included with the adapter) from this port to your TV’s HDMI input.
- Power Input:
- Micro USB Female: For connecting a power source (e.g., your phone’s wall charger) to power the adapter and charge the connected mobile device.
