An HDMI port (High-Definition Multimedia Interface) is a common connection found on many electronic devices, such as televisions, computers, and gaming consoles. It allows for the transmission of high-quality audio and video signals through a single cable, making it convenient for users to connect their devices without needing multiple wires. The HDMI port supports various resolutions, including 4K and 1080p, ensuring clear and vibrant images. It also carries digital audio, which enhances the overall viewing experience. Many modern devices come equipped with multiple HDMI ports to accommodate various peripherals and enhance connectivity options.
