A display cable is a type of cable used to connect a computer or other devices to a display, such as a monitor or television. It transmits video and sometimes audio signals, allowing users to see images and videos on a larger screen. Common types of display cables include HDMI, DisplayPort, and VGA. These cables come in various lengths and qualities, depending on the needs of the user. For example, HDMI cables are widely used for high-definition video and audio, while VGA cables are older and primarily support analog signals. Choosing the right display cable ensures optimal performance and compatibility with devices.
