Crestron CBL-8K-HD Certified HDMI 2.1 Cable, 48 Gbps
The CBL-8K-HD is Crestron's passive HDMI 2.1 interconnect, tested against version 2.1 of the HDMI Compliance Test Specification and carrying the Ultra High Speed label. It moves 48 Gbps between source and display, which is enough for 8K at 30 Hz 4:4:4 or 4K at 120 Hz 4:4:4 uncompressed, and 8K at 120 Hz 4:4:4 when the endpoints negotiate DSC. HDCP 2.3, HBR audio, CEC and EDID all pass through, along with the HDMI 2.1 feature set: Dynamic HDR, eARC, Variable Refresh Rate, Auto Low Latency Mode, Quick Frame Transport and Quick Media Switching.
Both ends terminate in a gold-plated 19-pin Type-A connector in a matte black boot. The jacket is thin for the bandwidth it carries, so it dresses cleanly behind a display and pulls through a rack without fighting the bend. Diameter grows with length, from 4.5 mm on the 3 and 6 foot runs to 6.0 mm at 9 feet, 8.0 mm at 12 feet and 9.0 mm at 22 feet. Choose the length above; each is a separate Crestron part number.
