An HDMI connector is a type of interface used to transmit high-definition video and audio from one device to another. Commonly found on devices like televisions, computers, and gaming consoles, it allows for a single cable connection, simplifying the setup of home entertainment systems. The HDMI standard supports various resolutions, including 4K and 1080p, making it suitable for modern displays. It also carries digital audio signals, eliminating the need for separate audio cables. This versatility has made HDMI the preferred choice for connecting devices in both home and professional environments.
