What type of cable is typically used for digital video connections?

Digital video connections rely on cables that can handle high-quality video signals without degradation or loss of quality. HDMI (High-Definition Multimedia Interface) and DisplayPort are designed specifically for digital transmission. They support high-definition video and audio simultaneously, making them ideal for modern video devices like televisions, computer monitors, and projectors.

HDMI is widely used in consumer electronics, offering features such as Deep Color, 3D support, and Ethernet capabilities, while DisplayPort is often utilized in computer displays and professional environments due to its ability to support multiple connections and higher resolutions.

In contrast, the other cable types mentioned do not primarily function for digital video. VGA and DVI cables, while associated with video, are largely older technologies, with DVI being capable of transmitting a digital signal but generally being replaced by HDMI. RCA and S-Video cables are analog formats that do not support high-definition video and lack the capability for audio transmission within the same cable system. Coaxial and Ethernet cables are used for other purposes — coaxial for cable TV and internet, and Ethernet for networking — and are not designed for direct video connections.
