What is HDMI?
High-Definition Multimedia Interface
HDMI is the industry-leading technology and de-facto standard connecting high-definition (HD) equipment, from HDTVs and personal computers to cameras, camcorders, tablets, Blu-ray players, gaming consoles, smartphones, and just about any other device capable of sending or receiving an HD signal. By delivering crystal-clear, all-digital audio and video via a single cable, HDMI technology dramatically simplifies cabling and helps provide consumers with the highest-quality HD experience. It transmits all HDTV standards and supports 8-channel, 192kHz, uncompressed digital audio, and all currently-available compressed formats, with bandwidth to spare to accommodate future enhancements and requirements.
What is the maximum length of an HDMI cable?
In short – no more than 10 Metres, with no more than 2 joins or couplers. However, this is a very subjective question, as it is not only the cable that factors into how long a cable can successfully carry an HDMI signal, the chipsets inside the source or the screen also plays a major factor and it isn’t possible to guarantee that any given combination of cables and equipment will perform adequately. Having performed substantial tests using our cable connected in a variety of scenarios, we have concluded that the majority of equipment will perform correctly with a total length of cable from source to screen of no more than 10 Metres, with no more than 2 joins or couplers.
