- The HDMI is the abbreviation of High-Definition Multimedia Interface.
- HDMI is one-way connection that connects digital audio/video sources such as a set-top box, an HD DVD disc player, a Blu-ray Disc player, a PC, video game console, or an AV receiver to a compatible digital audio device and/or video monitor such as a digital television (DTV).
- HDMI makes an uncompressed digital RGB connection from the source to the screen. By eliminating conversion to an analog signal, it delivers an unblemished image.
- The non-degraded signal reduces flicker and leads to a clearer picture. HDMI intelligently communicates the highest output resolution with the source device.
- The HDMI input is fully backward compatible with DVI sources but includes digital audio. HDMI uses HDCP copy protection.
