HDMI in HDMI cable is the abbreviated form of High Definition Multimedia Interface. This is now almost a standard feature in a wide variety of audiovisual devices. This 19-pin medium-sized connection carries pictures and sound at the same time using digital signals. A HDMI cable, which is capable of replacing separate digital audio connections like coaxial or optical leads, makes it easier for your audiovisual system to link together.
In keeping with its name, a HDMI cable is able to deliver high definition pictures as well as multi-channel digital soundtracks. It is also useful for high definition television receivers because it can carry some standard definition formats as well. This is so because some programs are not shown in high definition or with 5.1 surround sound.
It makes no sense to be miserly when looking for a cable for your expensive electronic devices. A higher grade HDMI cable is capable of carrying the highest resolution video, which uses 1080 progressively scanned lines, also known as 1080p. It is expected to climb up to 1440p soon. A high performance cable is essential for anyone who wants to connect across a long distance - to a projector mounted at a height for instance. Among some quality HDMI cables are Qunex HDMI-P from QED, Silver Serpent from Better Cables and XEN XHT658 from IXOS. HDMI, which is now being increasingly used in audiovisual devices, is available in various prices and various lengths.
