HDMI cable DELOCK 81683 — 3 m, HDMI Type A male-to-male, 48 Gbit/s, up to 7680×4320, gold-plated contacts, black

DELOCK 81683 is a 3 m HDMI Type A male-to-male cable designed to transmit high-resolution video and multichannel audio between devices with HDMI interfaces. With support for a maximum bandwidth of 48 Gbit/s, the cable can carry signals up to 7680 x 4320 @ 60 Hz and is suitable for applications requiring 8K Ultra HD. The cable has gold-plated contacts and a black braided jacket for reliable connection and protection.

Advantages

The cable supports Dynamic HDR and Dolby® Vision for improved colour depth, brightness and contrast, and includes eARC support to transmit uncompressed audio from the TV to an external sound system. Triple shielding, a coaxial cable design and a braided outer jacket enhance signal integrity and mechanical durability. Its 30 AWG conductor and gold-plated contacts help ensure stable data transfer up to 48 Gbit/s.

Suitable for

• Connecting Blu-ray players, set-top boxes and media players to TVs and projectors
• Linking gaming consoles or PCs to monitors and TVs for high-frame-rate gaming
• Connecting AV receivers or soundbars via TV with eARC for lossless audio
• Use in home cinema setups requiring 8K, 4K high refresh rates or wide aspect ratios

When it may not be suitable

This cable requires compatible source and display hardware to achieve maximum resolutions and refresh rates; older devices that do not support HDMI 2.1 features will be limited to lower bandwidths and formats. If very long cable runs beyond 3 m are required for signal integrity at the highest bandwidths, a different cable length or an active/optical HDMI solution may be more appropriate.

How to use

Connect one HDMI Type A male connector to the source device (for example a Blu-ray player, game console or PC) and the other HDMI Type A male connector to the display device (TV, monitor or projector). Ensure both devices are set to compatible HDMI settings (resolution, refresh rate and audio output). For lossless audio via eARC, enable eARC on the TV and the connected sound system where applicable. Check device manuals for specific HDMI mode and format support.

What to consider before purchase

• Ensure source and display devices support HDMI features you require (HDMI 2.1 features for 48 Gbit/s, 8K, high refresh rates, eARC).
• Confirm 3 m length is suitable for your installation; longer runs at full bandwidth may need active/optical solutions.
• Verify your devices support formats such as Dolby Vision, DSC or specific high refresh rates you intend to use.

Recommendations

Use this cable to connect HDMI 2.1-capable devices within a 3 m run for best results. Enable eARC on compatible TVs and receivers for uncompressed audio, and match device settings (resolution, refresh rate, colour sampling) to the capabilities listed to achieve desired performance.
