For 4K at 60 Hz HDMI 2.0 is enough. For PS5, Xbox Series X or Apple TV 4K (Gen 2+) with 4K at 120 Hz, VRR and ALLM you need HDMI 2.1 Ultra High Speed.
Standard copper HDMI 2.1 is safe up to 3 m, up to 10 m with premium copper. Beyond 15 m active HDMI or fibre HDMI up to 100 m.
For Apple TV 4K Gen 2 (2021) and Gen 3 (2022) yes. Apple TV 4K Gen 1 (2017) is HDMI 2.0.
The official HDMI 2.1 certificate at 48 Gbps. Guarantees 4K at 120 Hz, 8K at 60 Hz, VRR, ALLM and eARC.

Guide & know-how
HDMI cables at RPD — from the standard office HDMI to the HDMI 2.1 Ultra High Speed strand for PS5, Xbox Series X and Apple TV 4K (from Gen 2). HDMI 2.1 delivers 4K at 120 Hz or 8K at 60 Hz with Dynamic HDR, Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM) — mandatory for console gaming on modern TVs. Lengths 0.5 m to about 10 m of copper — for 15–50 m we offer active fibre HDMI. Ships from our Basel warehouse, same-day dispatch by 4 pm, free above CHF 15 and 2-year Swiss warranty. Invoice payment available (credit check by Powerpay).
Office/TV at 1080p: HDMI 1.4 is enough. 4K TV at 60 Hz or PS4 Pro: HDMI 2.0 (Premium High Speed, 18 Gbps). PS5 / Xbox Series X / Apple TV 4K (Gen 2): HDMI 2.1 Ultra High Speed (48 Gbps) for 4K at 120 Hz, 8K at 60 Hz, VRR and ALLM. Dolby Vision Gaming and Auto Game Mode also need 2.1. Look for the official Ultra High Speed Certification logo with QR code for authenticity.
HDMI 2.0 = 18 Gbps → 4K@60 Hz HDR / 1080p@240 Hz. HDMI 2.1 = 48 Gbps → 4K@120 Hz / 8K@60 Hz / 10K@120 Hz with DSC. Extra 2.1 features: VRR (variable refresh rate, eliminates tearing in console games), ALLM (auto low latency mode, lag-free console input), eARC (lossless Dolby Atmos / DTS:X) and Dynamic HDR per frame. Both are backwards-compatible — a 2.1 cable works on an old 1.4 TV too.
PS5, Xbox Series X / Series S, Nintendo Switch 2 (HDMI 2.1), Apple TV 4K Gen 2 (2021) and Gen 3 (2022) all deliver 2.1 features. Apple TV 4K Gen 1 (2017): HDMI 2.0. MacBook Pro M2/M3/M4 has a native HDMI output with 2.1 support (4K@240 Hz). Older MacBooks need a USB-C to HDMI adapter. OLED and Mini-LED TVs 2022+ have HDMI 2.1 (often on 2 of 4 ports), receivers with eARC need a 2.1 strand.
Copper HDMI is lossless up to about 10 m. Beyond 15 m you need active HDMI (built-in booster) or fibre HDMI (optical, up to 100 m). Braided jackets, gold-plated plugs and quad-shielded copper improve life and signal stability. Halogen-free LSZH jackets for fire safety in living rooms and offices, CE-EMC compliance is mandatory.
