HDMI extension cable ShiverPeaks 77479-3.0 — 3 m, Ultra HD, 3D support

HDMI extension cable ShiverPeaks 77479-3.0 is a 3-meter extension lead designed to lengthen an existing HDMI connection while maintaining Ultra HD resolution and 3D signal compatibility. The cable connects an HDMI male (A) plug to an HDMI female (A) coupler, enabling a quick extension without replacing the original HDMI cable. It is intended for use with displays, TVs, projectors and AV receivers where additional length is required.

Advantages

The extension preserves Ultra HD image quality and supports 3D signals, ensuring compatibility with modern high-resolution sources and displays. Gold-plated contacts improve corrosion resistance and signal transfer. The simple male-to-female design provides a flexible and reversible extension option without altering existing cable routing or connectors.

Suitable for

• Extending HDMI cable runs between media players and TVs or monitors
• Connecting projectors in meeting rooms where the original cable is too short
• Integrating with AV receivers or home-theater setups that require additional length
• Temporary or permanent installations where avoiding cable replacement is preferred

Key specifications

• Length: 3.0 m
• Connector type: HDMI male (A) to HDMI female (A)
• Resolution support: Ultra HD
• 3D signal support: Yes
• Contact finish: Gold-plated contacts

How to use

Insert the HDMI male (A) plug of the extension into the output port of your source device or into the existing HDMI cable plug, then connect the receiving HDMI cable or display device to the HDMI female (A) coupler. Ensure both connected devices are powered off when making the physical connection to reduce the risk of signal issues. After connecting, power on the devices and verify that the display resolution and 3D settings on source and display are set appropriately for Ultra HD and 3D content as needed.

Recommendations

For best results, use the extension in shorter overall cable runs to minimise potential signal degradation; avoid tight cable bends and keep the cable away from strong electromagnetic sources. If you experience any loss of resolution or signal, check connectors for secure seating and consider using a shorter or active extension solution for very long runs.
