HDMI cable is the standard choice for transmitting high-definition video signals due to its ability to carry both video and audio in a single cable. This technology supports resolutions up to 4K and beyond, offering superior quality compared to other types of cables. HDMI incorporates various digital video formats, providing improved color accuracy and detail, which are critical for high-definition content.

In contrast, coaxial cables are generally used for a variety of applications, including cable television, but do not specialize in high-definition video signal transmission. Composite video cables combine video signals into a single channel, resulting in lower quality compared to HDMI. S-Video cables separate video information into two channels for better quality than composite, yet they still do not reach the high-definition capabilities supported by HDMI. Thus, HDMI is recognized as the best option for delivering high-definition video signals effectively.
