Best 8K HDMI 2.1 Cables 2025 – Black Friday & Christmas Gift Guide UK
Don’t ruin your new PS5 Pro, Xbox Series X, Sky Q 8K box or LG/Samsung 8K TV with a cheap cable. Here’s exactly what you need for true 8K@60Hz, 4K@120Hz gaming, eARC Dolby Atmos and VRR – plus the lowest Amazon.co.uk Black Friday prices of 2025.
Why You Must Upgrade to HDMI 2.1 in 2025 (UK Edition)
Standard HDMI cables (18Gbps) can’t handle 8K, 4K@120Hz or advanced audio like Dolby Atmos over eARC. You need a certified Ultra High Speed HDMI 2.1 cable (48Gbps) with the official hologram label – anything else = lag, black screens or no soundbar audio.
