Tag details

An HDMI cable is a type of cable that enables you to make the best of what your high definition systems have to offer. HDMI, or high definition multimedia interface, refers to an audio/video interface used for transmitting data to equipment like high-definition television sets and home theater systems. Every newly manufactured television set is equipped with an HDMI connector and optimized cables that will deliver flawless 1080p digital video and eight-channel digital sound, allowing you the full benefits of your video and sound systems.

To ensure quality, a number of physical limitations apply to HDMI cables, one of which being their length. Signal attenuation (the gradual loss of intensity of any sort of flux through a medium) is the most important one, though this is heavily influenced by the very quality of the conducting materials used in the manufacturing of the cable, as well as the production process. Standard HDMI cables are usually 5 meters long (16 feet), but quality construction materials can produce cables of up to 15 meters long.

Common HDMIs can provide a bandwidth of 5 gigabytes per second (Gbps), which is about twice the amount needed to transmit clear multichannel audiovisual data. While more traditional video interfaces required two separate cables for audio and video input, the HDMI cable has plenty of bandwidth to speedily carry a complete signal and up to eight channels of perfect surround-sound.

HDMI cables can be separated into two main categories: standard and high-speed. Standard HDMI cables are tested at 74.5 MHz (for resolutions of up to 720p60 and 1080i60) and high-speed HDMI cables are tested at 340 MHz, for 1080p60 and 2160p30 resolutions. Additionally, both standard and high speed HDMI cables can be equipped with Ethernet, while automotive HDMI cables are produced to connect to embedded HDMI automotive connection systems in cars. Automotive cables are tested for high performance and will deliver powerful and reliable sounds, like any other HDMI cable.

Moreover, HDMI cables are a fast and easy way to hook up a computer or laptop to an HD television set, as more and more manufacturers acknowledge the market benefits of adding an HDMI output to their deices. Additionally, many HDMI cable manufacturers will guarantee their products for life.
