What does the High Definition Multimedia Interface (HDMI) not provide between connected devices?

The High Definition Multimedia Interface (HDMI) is designed to transmit both high-definition video and audio signals between devices, such as televisions, computers, and gaming consoles. It allows for the seamless transfer of these audio and video signals over a single cable, simplifying the setup and reducing the number of cables needed.

However, HDMI does not supply power to the connected devices. While there are other technologies that may provide power through a data connection, such as USB Power Delivery, HDMI's primary function is focused on the transmission of multimedia content. It doesn’t serve as a power source for devices, hence the correct understanding of this question emphasizes that HDMI cannot provide power to the connected device.

Other options, such as video and audio signals, are core functions of HDMI, and data transfer is also a part of its capabilities, particularly for control signals and certain types of metadata. Thus, the absence of power provision distinguishes HDMI clearly from other interfaces that might include power delivery features.
