Which type of port is typically used for high-definition audio and video output?

HDMI (High-Definition Multimedia Interface) is designed specifically for transmitting high-definition audio and video from a source device to a display. It has become the standard connection type for TVs, projectors, and monitors, allowing for the transfer of digital video and multi-channel audio over a single cable. This capability makes it particularly popular in home theater setups, gaming consoles, and computer monitors.

In contrast, while DisplayPort is also capable of carrying high-definition video and audio signals and is a strong contender for computer monitors, it is more commonly used in PC environments and less so in consumer electronics than HDMI. VGA, on the other hand, is an older analog standard that does not support high-definition signals and has been largely replaced by digital interfaces like HDMI and DisplayPort. USB-C can also transmit audio and video, especially with support for DisplayPort Alt Mode, but its primary function is as a versatile data and power connector rather than being dedicated specifically for high-definition multimedia use.

Thus, HDMI stands out as the most recognized and widely implemented port for high-definition audio and video output.
