4K is already 2015 standard... What about 8K ? MHL Consortium is looking to future-proof its TV-out connector with the new superMHL standard. Laughing in the face of 4K TVs everywhere the new connector can output 8K video @120 frames per second and 48-bit color depth. Our condolences to internal storage and microSD cards alike.
The superMHL connector supports HDR imagery and can power multiple display, up to 8, from a single source. When connecting to multiple devices (TV, disc player, AV receiver), it can unify their controls so you only need one remote. The connector can practically operate a small cinema with support with Dolby Atmos, DTS-UHD and 3D audio support.
And because outputting 8K@120fps can't be easy, the connector will also supply 40W of power. To cut down on frustration the new Type C connector can be plugged in either way, similar to the new USB standard. superMHL steps on even more USB toes by offering a data connection between devices.
