Short for High-Definition Multimedia Interface, HDMI is a connector and cable capable of transmitting high-quality and high-bandwidth audio and video streams between devices. The HDMI technology is used with devices such as an HDTV (high-definition television), Projector, DVD (digital versatile disc) player, or Blu-ray player.

HDMI cable information
The HDMI standard was developed by multiple companies, including Hitachi, Philips, Sony, and Toshiba. A single HDMI cable replaces the three composite audio/video cables, making connecting two devices for transmitting audio and video signals easier. HDMI can transmit standard, enhanced, and high-definition video signals and up to 8-channels of digital audio signals.
What are the different lengths of HDMI cables?
The length of HDMI cables varies significantly. They can run from one foot up to 50 feet, though it's not recommended that users buy more than a 25-foot cable as it may result in signal degradation or loss.
Where are the HDMI ports on the back of the computer?
The HDMI ports are found either on the video card or the motherboard on the back of the computer. It is important to note that not all computers and video cards have HDMI connectors; your computer may use Display Port, DVI (digital visual interface), or VGA (video graphics array) technology.
