Display interfaces are the connections that allow devices like computers, televisions, and projectors to communicate with screens. They transmit video and audio signals, enabling the display of images and sounds. Common types of display interfaces include HDMI, DisplayPort, and VGA, each with its own specifications and capabilities. These interfaces vary in terms of resolution support, refresh rates, and additional features like audio transmission. For instance, HDMI is widely used for high-definition video and audio, while DisplayPort is favored for high-performance gaming and professional applications. Understanding these interfaces helps users choose the right connections for their devices.
