MHL 3.0 unveiled with support for 4K video, enhanced audio, touchscreen input and more

MHL 3.0

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…
