The MHL Consortium just announced the next version of itswired connectivity standard which you can meet on many smartphones lately, mainly Samsung, HTC and LG ones.
MHL 3.0 is backwards compatible, which means it will work with your existing dongles, and can use just five pins to function, so it's connector-agnostic and can be rolled into the microUSB port, just like what we have now. The Consortium jazzed things up significantly, introducing 4K video support for that expensive TV you haven't even bought yet, but will do in a year or two.
A fast bi-directional channel allows you to hook up peripherals such as touch screens, keyboard and mouse, while doing the 4K streaming, and your phone or tablet are also charged by your TV in the process. Here's the full changelog:
- 4K (Ultra HD): Support of 4K formats up to 2160p30
- Simultaneous high-speed data channel
- Improved Remote Control Protocol (RCP) with support for peripherals such as a touch screen, 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
The MHL 3.0 standard specs will be available on the Consortium's website next month, so that manufacturers can grab them, and start equipping our smartphones and tablets with 4K-capable wired connectivity.
