StarTech ST121HD20V HDMI over CAT6 Extender, 4K 60Hz | AV Accessory

Preserve full-resolution HDMI performance across long cable runs with the StarTech ST121HD20V. Built for installations that need dependable signal extension, it carries UHD content up to 4K 60Hz over CAT6 at distances up to 165 ft (50 m). HDR support and 4:4:4 chroma subsampling help maintain color fidelity and text clarity, which matters in presentation spaces, control rooms, and signage environments. This extender is designed to work with existing CAT6 infrastructure, reducing the need for new cabling while keeping the signal path direct and predictable. HDCP 2.2 compliance supports protected content playback from modern HDMI sources, and backward compatibility with earlier HDMI and HDCP generations adds flexibility in mixed-device environments. For teams standardizing AV deployments, that means fewer compatibility surprises and a cleaner path to scaling across rooms or buildings. When display quality and distance both matter, this model delivers the kind of signal integrity that cheaper extenders often struggle to maintain. It is a practical choice for integrators and IT teams that need consistent output, not just basic connectivity.
