Video interfaces are the connections that allow video signals to be transmitted between devices, such as computers, televisions, and projectors. Common types of video interfaces include HDMI, DisplayPort, and VGA. Each interface has its own specifications and capabilities, affecting video quality, resolution, and audio transmission. These interfaces play a crucial role in modern technology, enabling high-definition video playback and seamless connectivity. For instance, HDMI is widely used in home entertainment systems for its ability to carry both video and audio signals through a single cable. Understanding these interfaces helps users choose the right connections for their devices.
