With its replacement the SuperMHL, we’ll go up a gear, since we’re talking about picture quality Ultra HD 8K (7,680 x 4,320 pixels) to 120fps (frame per second). We are also talking about a power of 40 Watts for recharging. Users will also appreciate the connector that can be inserted in both directions on the smartphone side, thanks to the use of USB Type C technology.

Final specifications will be made available at the end of January by the MHL Consortium.

In version 1.3, the DisplayPort does not exceed 120 frames per second in 4K. In version 2.0, HDMI does not exceed 60 frames per second in 4K. It will also be necessary for the SoCs equipping smartphones to be able to offer such a video stream.
