MHL announced the MHL 3.0 specification with double the bandwidth compared to the previous specification, delivering 4K (Ultra HD) resolution and a wider color gamut. By using a bi-directional channel that’s significantly faster than MHL 2, the new specification enables concurrent 4K video, and high-speed peripheral support of mass storage and input devices such as a touchscreen, keyboard and mouse.
The MHL 3.0 specification capabilities include:
- 4K (Ultra HD) Support of 4K formats up to 2160p
- Simultaneous high-speed data channel
- Improved Remote Control Protocol (RCP) with support for peripherals such as a touchscreen, keyboard and mouse
- Power charging up to 10W
- Backward compatible with MHL 1 and MHL 2
- Latest HDCP 2.2 content protection
- Enhanced 7.1 surround sound with Dolby TrueHD and DTS-HD
- Connector agnostic – uses as few as five pins
- Support for simultaneous multiple displays
Unfortunately, MHL’s press release failed to mention when we’ll see the first MHL 3.0-enabled mobile devices; guess we’ll have to wait a little longer to get that information…
