The cable offers support for Ultra HD 4K video, audio return channel and high-speed Ethernet so that you can enjoy all the benefits that the latest technology has to offer. The cable is also backwards compatible with previous HDMI versions and therefore, can be used to extend or mirror displays to enable the delivery of PowerPoint presentations at school or office. Its moulded strain-relief and corrosion-resistant 24K gold-plated connectors provide stability and durability to the cable while the triple shielding used in its construction helps protect against external signal interference and minimize any signal loss.
