HDMI cable Unitek C137W 1.5 m, HDMI 2.1, 48 Gbit/s, 4K/8K 2160p, 120 Hz, ARC, Ethernet, gold-plated

The UNITEK C137W HDMI cable 1.5m provides a direct HDMI Type A to HDMI Type A connection designed for modern AV systems. Supporting HDMI 2.1 and a data throughput of up to 48 Gbit/s, the cable is suitable for transmitting high-resolution video and multi-channel audio between compatible devices. It includes support for 3D formats and Audio Return Channel (ARC), and the gold-plated contacts are intended to improve conductivity and resist corrosion. The cable's black outer jacket offers a neutral appearance that fits home and office setups.

Advantages

This HDMI cable delivers high bandwidth performance compliant with HDMI 2.1 feature set, enabling higher frame rates and increased colour depth where source and display support those modes. Gold-plated contacts reduce contact resistance and help maintain signal integrity over repeated connections. The 1.5 m length offers a balance between flexibility and minimal signal loss for typical living room and desktop arrangements. The standard HDMI Type A connectors ensure compatibility with a wide range of TVs, monitors, game consoles and AV receivers.

Suitable for

• Connecting 4K/8K capable TVs and monitors to Blu-ray players, game consoles, and streaming devices (when both devices support corresponding HDMI 2.1 features)
• Linking computers and laptops with HDMI output to external displays or projectors
• Home theatre setups using ARC-enabled audio systems or soundbars
• Use with gaming consoles where high bandwidth is required for higher frame rates and enhanced video features

How to use

Insert one HDMI Type A connector into the HDMI output of your source device (for example a Blu-ray player, console or PC) and the other connector into the HDMI input on your display or AV receiver. Ensure both devices are powered on and set to the correct input. For ARC functionality, enable ARC in both the TV and the connected audio device settings. To achieve HDMI 2.1 features such as higher refresh rates or expanded colour depth, confirm that both source and display support the specific HDMI 2.1 modes and configure device settings accordingly.

Recommendations

For optimal performance, avoid sharp bends and kinks in the cable and maintain a secure connection at both ends. When using features that require high bandwidth (e.g., 4K at high refresh rates or 8K), verify device compatibility and use the full 1.5 m length without unnecessary extension to reduce potential signal degradation.
