HDMI cable TB AKTBXVH21FLAT30 — 3 m, HDMI 2.1, flat, black

TB HDMI cable AKTBXVH21FLAT30 is a 3 m flat HDMI 2.1 cable in black designed for low-profile routing behind TVs, monitors or furniture. The flat form factor reduces bulk and makes it easier to run the cable through tight gaps, along walls and under carpets while maintaining the capabilities of the HDMI 2.1 specification for high-bandwidth video and audio transmission.

Advantages

The flat construction allows discreet installation and simpler cable management in wall-mounted or confined setups. Support for HDMI 2.1 ensures compatibility with higher resolutions and refresh rates, while a 3 m length provides flexibility for common home and office placements. The cable’s black finish blends with most AV equipment and interiors.

Suitable for

• Connecting 4K/120Hz or 8K-capable TVs and monitors to consoles, PCs or AV receivers that use HDMI 2.1 features.
• Installing behind wall-mounted TVs where a low-profile cable is required.
• Routing along skirting boards, under carpets or inside AV furniture where space is limited.
• General home theatre and gaming setups requiring a single-cable video and audio connection.

When it may not be suitable

For very long runs beyond 3 meters, signal degradation may occur depending on the devices and display resolution; in such cases an active cable or signal repeater may be necessary. If a thick, highly durable or braided cable is required for heavy-duty installation or frequent handling, this flat, low-profile cable may not provide the desired mechanical robustness.

Key specifications

• Cable type: HDMI 2.1 compatible
• Length: 3 metres
• Form factor: flat profile for low clearance routing
• Colour: black
• Intended signals: digital video and audio (HDMI features depending on connected devices)

How to use

Connect one HDMI connector to the HDMI output of your source device (for example a game console, PC or set-top box) and the other connector to the HDMI input of your display or AV receiver. Route the flat cable along the desired path—behind a TV, along a wall or under a carpet—taking care not to crease the cable sharply. Ensure both connected devices are powered and set to the correct input; adjust display settings on source and sink devices to enable desired resolutions and refresh rates supported by HDMI 2.1.

What to consider before purchase

• Confirm that your source and display support the HDMI 2.1 features you need (resolution, refresh rate, HDR, VRR, eARC).
• Measure the required cable run to ensure 3 m length is sufficient for your setup.
• Decide if a low-profile flat cable meets your durability needs or if a thicker, braided cable is preferable for frequent handling.

Usage recommendations

For optimal performance, avoid tight bends and protect connection points. If you plan to use the cable for the highest bandwidth modes (e.g., 8K or 4K at very high refresh rates), verify device compatibility and settings. For longer distances or installations with many connectors, consider an active HDMI solution or repeater.
