High-Definition Multimedia Interface (HDMI) is a standard for transmitting high-quality video and audio signals between devices such as TVs, monitors, gaming consoles, and Blu-ray players. HDMI cables deliver uncompressed digital signals, ensuring high-definition video and audio performance with minimal loss in quality. HDMI ports have become the standard for connecting multimedia devices, offering a single connection for both audio and video, which simplifies setup. HDMI has evolved to support 4K and 8K video, making it essential for home theater systems, gaming, and professional video production.
