Top parameters of audio-video signal The secret to good cables is not a decorative braid or nice plugs, but a kind of used conductive veins. Therefore, in long HDMI cables Unitek used thick (from 28 to 24 AWG – the smaller the larger the diameter), multi-wire copper veins. The cables are screened 7 times, which minimizes the impact and emission of electromagnetic interference – they are fully safe. In addition, twisted veins have better bending resistance, making the cable more flexible and convenient to fit. New HDMI 2.0 features HDMI 2.0 cable offers transfer to 18 Gbps. With such high bandwidth you can use the latest technologies such as ARC (reverse audio channel), HDR, EDID (automatic parameter detection), 3D, CEC and display 2 different images at the same time. The extraordinary parameters of the image match the sound that guarantees the lossless Dolby True HD and DTS-HD. With care for every detail Unitek also cares about the functional aspects of the goods supplied. The cables are packed in aesthetic cardboard boxes. Each wire is a band to control its course. The tips are secured with anti-dust plugs - they facilitate its drag in tight troughs - and wrapped safety tape. The gold plating protects them from corrosion and stabilizes the signal. All this to make the wire serve for years. You can extend the warranty for an additional year by registering the purchase by the Unitek Search app (https://guarantee-unitek.pl/).
