HDMI cable Unitek C138W 2 m — HDMI 2.1, 48 Gbit/s, 4K/120Hz, HDR10 & Dolby Vision, ARC, gold-plated connectors

The UNITEK C138W 2m HDMI cable is a two-meter HDMI Type A to Type A lead designed for connecting displays, TVs, projectors and AV receivers. Compliant with HDMI 2.1 specifications, it supports high bandwidth transmission up to 48 Gbit/s and carries video, audio and control signals over a single cable. The cable features gold-plated contacts and a two-tone grey and black jacket for a durable, low-profile connection between source devices and displays.

Advantages

This HDMI cable provides a high-bandwidth link capable of carrying up to 48 Gbit/s, enabling support for higher resolution and refresh rate combinations defined by HDMI 2.1. Gold-plated contacts improve contact reliability and help reduce corrosion over time. The 2 m length offers flexibility for typical living-room and desktop setups while keeping cable runs tidy. A single-cable connection transmits video, multi-channel audio and control signals, reducing the need for multiple interconnects.

How to use

Determine the source device (for example a Blu-ray player, game console or PC) and the display or audio device you want to connect. Insert one HDMI Type A connector into the HDMI output of the source and the other connector into the HDMI input of the display or AV receiver. Ensure connectors are fully seated to establish a secure connection. Once connected, select the appropriate HDMI input on the display device and configure resolution or audio settings on the source device as needed to match the capabilities of the display and the HDMI 2.1 bandwidth.

Recommendations

For optimal performance, avoid tight bends or kinks in the cable and keep the length run within reasonable limits to prevent excessive signal attenuation. If using advanced HDMI 2.1 features (high frame rates, high resolutions, variable refresh rate), verify that both connected devices support those features and that device firmware is up to date.
