Short for High Definition Multimedia Interface, HDMI is a connector and cable capable of transmitting high-quality and high-bandwidth streams of audio and video between devices. The HDMI technology is used with devices such as an HDTV, Projector, DVD player, or Blu-ray player. The picture to the right is an example of an HDMI cable.
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 it easier to connect two devices together for transmitting audio and video signals. HDMI is capable of transmitting standard, enhanced, and high-definition video signals, as well as 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 all the way 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 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, or VGA technology.
