HDMI, or High-Definition Multimedia Interface, is widely recognized as the standard cable used for high-definition video connections. It is specifically designed to transmit both high-definition video and multi-channel audio signals through a single cable, making it highly efficient for connecting devices such as televisions, projectors, and gaming consoles. The HDMI standard supports various resolutions, including 1080p and 4K, ensuring compatibility with modern high-definition display technologies.

In contrast, other cables have different functions; for instance, USB cables are primarily designed for data transfer and device charging rather than high-definition video. VGA connections, while capable of transmitting video, are limited to standard definition and do not carry audio, making them less suitable for high-definition applications. Ethernet cables are used for network connectivity and data transmission over local area networks (LAN), not for video signals. Thus, HDMI is the clear choice for high-definition video connections due to its comprehensive capabilities in transmitting both video and audio efficiently.
