The Club 3D CAC-1322 Ultra High Speed HDMI2.1 extension cable is designed for the transmission of video and audio signals in the highest quality. HDMI 2.1 increases the bandwidth to 48Gbps. The increase in maximum bandwidth compared to previous versions is achieved by increasing the bit rate of the data channels (from 6Gbps to 12Gbps) and the number of channels (from 3 to 4). This enables the support of resolutions up to 4K120Hz or 8K60Hz. One function in this specification is Display Stream Compression (DSC) 1.2, which is used for video formats above 8K with 4:2:0. Improved refresh rate functions: Variable Refresh Rate (VRR) reduces or eliminates lag, judder and frame tearing for smoother motion in games. Quick Media Switching (QMS) for movies and videos eliminates the delay that can lead to blank screens before content is displayed. Quick Frame Transport (QFT) reduces latency. HDMI 2.1 also supports static and dynamic HDR metadata. All HDMI 2.1 functions are fully supported by this Club 3D CAC-1322 cable. It is the ideal solution for the ultimate future-proof HDMI 2.1 experience.
