Only licensed and certified cables can give assurance to support all HDMI 2.1 functions. Other HDMI standards like 2.0 and 1.4 are fully compatible with this cable. The amount of data transmitted by HDMI 2.1 cables of the ultra high-speed class is 48 gigabits per second. This speed makes it 167% faster than the older high-speed cables which could only provide 18 gigabits per second. This extensive bandwidth has been made possible by high-purity copper lines, strong shielding made of tinned copper, and extremely low manufacturing tolerances. With this huge data rate, this HDMI ultra-high-speed cable not only transmits videos of 4k resolution at 120 Hertz but also images of 8k resolution for bigger televisions. Even a 10k resolution with 10,240*4,320 pixels is possible. But the screens suitable for this resolution are not out there in the market yet. The standard 2.1 cable enables not only vivid and more detailed images but also conducts a lot of improvements for home cinema or gaming. It gives us functions like Dynamic HDR, VRR, or eARC. HDR is the short form for High Dynamic Range. The previous HDR technology provided features like high contrasts, for example, differences in brightness. In this feature brightly lit areas of an image stand out more clearly. What more is required of this feature is, static with HDR films, meaning that it must be identical for the entire length of a film. The dynamic HDR technology of HDMI standard 2.1 is able to handle strong fluctuations in brightness. Because of this additional setting, the contrast information is adjusted separately for each screen, or even for every single image of every frame. The picture looks more lifelike. The auto-low latency mode of this cable puts the television on gaming mode. This is more suited for gamers. The variable refresh rate mode synchronizes the frame rate of a television with the output signal of a gaming PC.
