HDMI cable Unitek C11072BK-20M 20 m, HDMI 2.0, max resolution 4096×3112, black

The UNITEK C11072BK-20M is a 20 m fiber HDMI cable designed for long-distance, high-bandwidth audio and video transmission. It supports up to 4K@60Hz with 4:4:4/4:2:2/4:2:0 chroma subsampling, HDR and Dolby Vision, HDCP 2.2, ARC and 3D. The hybrid fiber construction and 24K gold-plated connectors provide a stable 18 Gbit/s data rate and lossless signal over long runs while the slim, flexible jacket suits installation in confined spaces.

Advantages

This HDMI cable delivers full 18 Gbit/s bandwidth using high-quality glass fiber to minimize signal attenuation across 10–50 m distances. 24K gold-plated plugs and metal housings improve contact reliability and corrosion resistance, while hybrid shielding reduces electromagnetic interference. The slim 4.8 mm diameter and 25 mm bending radius allow routing through narrow channels or wall paths without compromising performance.

Suitable for

• Connecting 4K Blu-ray players, Apple TV and media players to 4K TVs or projectors
• Wiring gaming consoles (PS4, PS3, Xbox One, Xbox One S) to displays at longer distances
• Home theater and AV installations requiring ARC and 3D support
• PC or laptop to 4K monitors or projectors where a 20 m run is needed

How to use

Connect one HDMI Type A end to the source device (Blu-ray player, console, media player or laptop) and the other end to the display (TV, monitor or projector). Ensure both devices support the target resolution and HDR formats. Use the TV or source device menu to enable ARC or HDCP 2.2 features if required. Avoid tight bends below the specified 25 mm radius to maintain signal integrity.

Recommendations

For reliable long-distance performance, route the cable away from strong EMI sources (large transformers, heavy machinery) and secure it along walls or cable channels. If wall installation is required, check local regulations and use appropriate in-wall rated conduits if necessary.
