MHL
— the MHL interface is wired and is quite widely used in mobile devices as a means of broadcasting a high-quality video signal to external screens. Its bandwidth is enough to transmit high-definition video and multi-channel audio (Full HD in early versions, UltraHD with lossless audio decoders in later versions), in addition, a receiver or other signal receiver also plays the role of a charger when connected. Therefore, support for this standard will be very useful if you plan to use a smartphone or tablet with MHL as a signal source.
