HDMI cable Secomp S3708 — STANDARD 8K Ultra HD with Ethernet, ST/ST connector, 3 m, black

The Secomp S3708 STANDARD 8K HDMI Ultra HD cable is a 3 m black HDMI lead designed to carry high-resolution video and multichannel audio between source devices and displays. With support for up to 8K resolution and an integrated Ethernet channel, this cable is intended for systems that require high bandwidth and reliable wired connectivity, such as TVs, monitors, media players, game consoles and AV receivers in both home and professional environments.

Advantages

The cable supports Ultra HD video transmission up to 8K and carries multichannel digital audio, providing a single-cable solution for high-bandwidth AV signals. An integrated Ethernet channel enables network-capable devices to share an internet connection without a separate network cable. ST/ST connectors on both ends ensure a standard HDMI interface for easy plug-and-play installation and compatibility with a wide range of consumer and professional equipment. The 3 m length offers a practical balance between reach and signal integrity for typical room layouts.

Suitable for

• Connecting 8K or 4K TVs and monitors to media players and set-top boxes
• Wiring game consoles to displays where high refresh and resolution are required
• Linking AV receivers and home theatre components for multichannel audio and video
• Professional AV setups where a reliable HDMI connection with Ethernet is needed

When it may not be suitable

This 3 m HDMI cable is not intended for very long runs beyond typical room distances; signal attenuation and potential need for active repeaters should be considered for lengths significantly greater than 3 m. It also does not replace specialized cables required for non-HDMI interfaces or proprietary connections.

Key specifications

• Supported resolution: up to 8K (Ultra HD)
• Audio: multichannel digital audio support
• Ethernet: integrated HDMI Ethernet Channel
• Connectors: HDMI standard (ST) on both ends
• Length: 3 metres
• Color: black

How to use

Connect one end of the Secomp S3708 HDMI cable to the HDMI output of the source device (for example, a Blu-ray player, game console or media streamer) and the other end to the HDMI input on the display or AV receiver. Ensure both devices are powered off when making the connection, then power them on and select the correct HDMI input on the display. If Ethernet functions are required, enable HDMI Ethernet/ARC settings in the device menus if available. For optimal performance, avoid tight bends and sharp kinks in the cable and keep it away from large sources of electromagnetic interference.

What to consider before purchase

• Verify that your source and display devices support the target resolution and features you need (for example, native 8K or relevant HDR/refresh rate capabilities).
• Confirm that a 3 m length suits your installation; for longer distances consider active or fiber HDMI solutions.
• Ensure devices accept standard HDMI connectors and that no proprietary adapters are required.

Usage recommendations

For consistent high-resolution performance, route the cable without tight bends, avoid running it parallel to power cables for long stretches, and use the closest HDMI input on your display that supports the desired features (for example, the port labelled for high bandwidth or enhanced formats).
