hdmi arc vs hdmi mhl

HDMI ARC (Audio Return Channel) and HDMI MHL (Mobile High-Definition Link) are both technologies used in HDMI (High-Definition Multimedia Interface) connections, but they serve different purposes. HDMI ARC allows audio to be sent from a television to an external audio device, such as a soundbar or AV receiver, through the same HDMI cable used for video. It enables a simplified setup and eliminates the need for extra audio cables. On the other hand, HDMI MHL is designed specifically for connecting mobile devices, like smartphones and tablets, to external displays such as TVs or monitors. It enables high-definition video and audio transmission, and also charges the connected device simultaneously. In summary, HDMI ARC facilitates audio transfer from the TV to external audio devices, while HDMI MHL supports high-quality video and audio connections between mobile devices and external displays.
