The Club 3D CAC-1374 Ultra High Speed HDMI 2.1 cable is built to handle the highest quality video- and audio- signals. The increase in maximum bandwidth compared to previous versions is achieved by increasing both the bitrate of the data channels (from 6Gbps to 12Gbps) and the number of channels (from 3 to 4). This allows support for resolutions up to supports 4K at 120Hz.
