Which interface was developed for high-definition televisions and used with computers?

HDMI, or High-Definition Multimedia Interface, was specifically developed to transmit both high-definition video and audio over a single cable, making it particularly well-suited for high-definition televisions. The technology allows for a seamless connection between devices such as computers, Blu-ray players, and televisions. HDMI supports a wide range of resolutions and formats, including 4K and 3D, as well as features like CEC (Consumer Electronics Control), which enables the control of multiple devices through one remote. This versatility and capability to carry both video and audio signals without the need for separate cables make HDMI the standard interface for connecting high-definition devices.

Other interfaces like USB, VGA, and Thunderbolt serve different purposes. USB is primarily designed for data transfer and connecting peripherals rather than high-definition video and audio. VGA (Video Graphics Array) is an older analog standard that does not support HD formats and is limited to video only, lacking audio transmission capabilities. Thunderbolt, while capable of high-speed data transfer and video output, is not as commonly used for standard consumer electronics as HDMI is. Therefore, HDMI stands out as the answer due to its specific design for high-definition audio and video applications and its widespread adoption in both the computer and television markets.
