Carry high-resolution video and multichannel audio across a 12 ft HDMI connection where shorter patch leads cannot reach.

It supports HDR10+ and Dolby Vision for compatible displays and source equipment, while retaining backward compatibility with earlier HDMI equipment. Use the cable between a workstation, dock, AV receiver, media source, display, or projector when the installation requires HDMI 2.1 throughput. It also works with USB-C to HDMI adapters, including adapters used with desktop systems and Apple M-series MacBook Air, MacBook Pro, and MacBook Max systems. Connector markings help identify cable ends during installation and troubleshooting. Audio support includes 7.1 TrueHD, eARC, Dolby Atmos, and DTS:X for installations carrying video and immersive audio over one HDMI cable. A flexible TPE jacket helps route the cable around furniture, display mounts, and equipment racks, with a stated minimum bend radius of 30 mm. The 12 ft length distinguishes this version for longer display-to-source connections while retaining certified HDMI 2.1 performance.
