ACT AK3874 HDMI cable 3 m HDMI Type A (Standard) Black

The ACT AK3874 HDMI cable is a 3 m Premium High Speed v2.0 HDMI-A to HDMI-A lead designed for reliable transmission of 4K@60Hz video and multi-channel audio. It features full copper conductors and gold-plated contacts for consistent signal quality, a Low Smoke Zero Halogen (LSZH) jacket to reduce toxic gas emissions in case of fire, and an additional thin plate shielding layer to limit electromagnetic and radio-frequency interference.

Advantages

This HDMI cable supports 3840x2160 @ 60Hz and HDR content while providing an 18 Gbit/s bandwidth and compatibility with features such as ARC, HDCP 2.2, EDID, Dolby TrueHD and DTS-HD Master Audio. The full copper conductors and gold-plated contacts promote stable connectivity and minimal signal loss, and the LSZH jacket adds safety in enclosed or public environments. Thin plate shielding lowers RFI/EMI, making the cable suitable for installations near sensitive electronics.

Suitable for

• Connecting 4K displays, TVs and projectors to Blu-ray players, set-top boxes and media players
• AV installations in meeting rooms, lecture halls and conference centers
• Medical imaging displays and other sensitive equipment where low EMI/RFI is important
• Onboard vessel displays and navigation systems
• Monitoring and control displays in data centers

Когда это может не подойти

This cable is intended for HDMI Type A connections and standard straight male-to-male use; it is not suitable if you require different connector types (e.g., HDMI micro/mini, DisplayPort, DVI) or angled/low-profile plugs for very tight spaces. For resolutions or refresh rates beyond 4K@60Hz (for example 4K@120Hz or 8K), a higher-specification cable or HDMI version may be required.

• Supports HDR, ARC, multi-channel audio, HDCP 2.2, EDID
• Conductor: full copper
• Contacts: gold-plated
• Cable jacket: Low Smoke Zero Halogen (LSZH)
• Shielding: additional thin plate shielding for reduced EMI/RFI
• Colour: black

How to use

Connect one HDMI Type A male end to the HDMI output on the source device (for example a Blu-ray player, media player or computer) and the other end to the HDMI input on the display or projector. Ensure both devices are powered off when connecting if recommended by the device manufacturers, then power on and select the appropriate HDMI input on the display. Configure resolution and HDR settings in the source device or display menu as needed to obtain 3840x2160 @ 60Hz and enable ARC if required for audio return.

What to consider before purchase

• Verify both devices use standard HDMI Type A ports and that a 3 m cable length suits your installation
• Check whether you need higher bandwidth for refresh rates or resolutions beyond 4K@60Hz
• Consider whether an LSZH jacket is required for your environment (public buildings, vessels, data centers)
• Ensure cable routing allows for straight male connectors without sharp bends at the ends

Usage recommendations

For best results, avoid tight bends near the connector ends, keep the cable away from strong sources of electromagnetic noise, and set source and display devices to matching resolution and HDR modes. Use the LSZH jacketed cable where reduced toxic gas emissions are a safety requirement.
