8K HDMI 2.1 Cable – Powerful 48Gbps Ultra High-Speed Cord

8K HDMI 2.1 cable technology is what separates a display that merely turns on from one that shows everything your source device can actually output. The Dtech DT-H8030 is a 48Gbps, HDMI 2.1-certified copper cable built for the next generation of TVs, monitors, gaming consoles, and AV equipment — without the bandwidth bottlenecks that older HDMI 2.0 cables can’t get past.

Why Choose This 8K HDMI 2.1 Cable

Most HDMI cables on the market are still rated for HDMI 2.0’s 18Gbps ceiling, which caps out well below what modern 8K and high-refresh 4K sources need. This cable is rated for the full 48Gbps HDMI 2.1 bandwidth, so it can carry:

• 8K@60Hz for 8K displays and media players
• 4K@120Hz for high-refresh gaming on PS5, Xbox Series X/S, and RTX 30/40-series GPUs
• Dynamic HDR for scene-by-scene brightness and colour accuracy, with 12-bit colour depth for smoother gradients and fewer visible bands of colour
• eARC for lossless, uncompressed audio passthrough to a soundbar or AV receiver, including 24-bit/192kHz audio and Dolby Atmos, DTS:X, or 7.1/5.1 surround
• VRR and ALLM support for stutter-free, low-latency gaming on compatible displays

Build Quality: Gold-Plated Connectors & Braided, Shielded Design

Bandwidth on a spec sheet only matters if the cable can hold the signal without loss. The DT-H8030 uses a pure copper core with gold-plated connectors for corrosion resistance and consistent contact, wrapped in multi-layer shielding — including a magnesium-aluminium braided mesh — that reduces electromagnetic interference, the usual cause of dropped signal, flickering, or HDCP handshake errors on long or budget cables. The outer jacket is braided PVC over a cotton mesh layer for pull and bend resistance, and the connector housing uses a zinc-alloy shell built for repeated plug/unplug cycles at the back of a TV, console, or AV rack without the pins wearing loose. It’s backed by a 1-year warranty.

Length Options: 0.5m to 8m

This is a copper HDMI 2.1 cable, available in lengths from 0.5m up to 8m, so you can size it to the actual gap between your source and display — a short 0.5m–1m run for consoles sitting right next to the TV, or up to 8m for a wall-mounted display, a media cabinet across the room, or a home theatre rack. (Note: copper HDMI cables lose signal integrity over long runs; if you need to go beyond 8m, look at our 8K HDMI 2.1 Fiber Optic Cable instead — a fibre-optic AOC cable that holds full 8K/4K120 bandwidth over much longer distances than copper can.)

Who This 8K HDMI 2.1 Cable Is For

• Gamers connecting a PS5, Xbox Series X/S, or RTX-40-series PC to a 4K120 or 8K-capable display who need VRR, ALLM, and full refresh rate without compression
• Home theatre setups using eARC to send Dolby Atmos or DTS:X audio to a receiver or soundbar without a separate optical cable
• AV installers and professionals wiring 8K displays, signage, or conference-room systems where signal reliability matters more than price
• Anyone upgrading to an 8K or 4K120 TV who’s finding their old HDMI cable can’t push the resolution or refresh rate the new display supports

Frequently Asked Questions

Is this cable backward compatible with HDMI 2.0 devices? Yes. It works with any HDMI-equipped device; on HDMI 2.0 sources or displays, it will simply run at HDMI 2.0 speeds since bandwidth is capped by the weakest link in the chain.

What’s the maximum length available for this cable? This copper 8K HDMI 2.1 cable is available up to 8m. For longer distances, a fibre-optic or extender solution is recommended to maintain signal integrity.

Does it support VRR and ALLM for gaming? Yes, provided your source and display both support these HDMI 2.1 features (most current-gen consoles and gaming TVs do).

Will this cable actually output full 8K, or is that theoretical? The cable is rated for the 48Gbps bandwidth 8K@60Hz requires. Actual 8K output also depends on your source device and display both supporting 8K — the cable won’t bottleneck that connection.
