HDMI Cable Gembird CC-HDMI4-20M
The Gembird CC-HDMI4-20M is a 20 m HDMI cable with HDMI Type A connectors and gold-plated contacts, designed for transmitting high-definition digital audio and video signals over long distances. It offers a data transfer bandwidth of up to 10 Gbit/s, supports 3D video formats and high-resolution video up to 3840 x 2160 at 24/25/30 Hz and 4096 x 2160 at 24 Hz, and includes HDMI Ethernet Channel and Audio Return Channel support.
This HDMI cable provides stable high-bandwidth transmission suitable for long runs, thanks to gold-plated HDMI Type A connectors and shielding appropriate for a 20 m length. Support for up to 10 Gbit/s data rate enables 3D content and Ultra HD resolutions as specified. Built-in HDMI Ethernet Channel (HEC) and Audio Return Channel (ARC) functions allow device networking and audio routing without extra cables.
Connect one HDMI Type A end to the HDMI output of your source device (for example a Blu-ray player, set-top box or PC) and the other end to the HDMI input of your display device (TV, monitor or projector). Ensure both devices support the desired resolution and features (3D, Ethernet over HDMI, ARC). For long cable runs, route the cable away from strong electromagnetic interference sources and use secure connector seating to maintain signal integrity.
For reliable performance at 20 m length, verify that connected devices support the specified resolutions and refresh rates. If you experience signal loss or image instability, try reducing the resolution or using an active/repeater HDMI solution designed for longer-distance Ultra HD signals.
