MHL, the standard for sending high-definition video from portable devices, has today announced its version 3.0 specification. The highlights in MHL 3.0 include 4K video support (up to 2160p30) and the ability to use input devices and other peripherals — mice, keyboards, touchscreens, etc. — thanks to a higher-speed two-way link.

Also listed in the new spec are charging at 10W, 7.1 Dolby surround sound, HDCP 2.2 content protection and backwards compatibility with the MHL 1 and 2 standards. The standard will be "connector agnostic," according to the MHL group, with the ability to operate over as few as five pins.

The full MHL 3.0 specification will be available to download in early September. There's no indication as to when we might see the first smartphones and tablets with support for the new MHL standard, but as the spec has just been finalized, it's unlikely we'll see anything in the immediate future.
