8K Fiber Optic HDMI 2.1b Cable 50 Feet 48Gbps 8K60Hz 4K120Hz Dynamic HDR HDCP2.2/2.3 for RTX4080/4090/3080/3090, Xbox S/X, PS5/4, AVR, Projector, LG/Samsung/Sony TV

Ce cable fonctionne parfaitement. D'une longueur de 15 mètres, l'image est parfaite en 4k. Le cable est assez souple pour être inséré dans des gaines électriques. parfait. je recommande vivement.

Initially had an issue with flicker, but the manufacturer was incredibly helpful and sent out a replacement the next day, no questions asked. No issues with the replacement. Supports full RGB at 4k 144hz and no hiccups

I have tried dozens of hdmi cables at 4k 165hz with my LG G5. All of them gave me a black screen issue. Some people recommended me this cable. The first one I got had also a black screen issue, but Ruipro support immediately resolved this issue by sending a new one. I never expected to receive any kind of support for a hdmi cable. Will gladly buy from them again.

​If you’ve tried running a standard copper HDMI cable over 5 metres for a PS5, Xbox Series X, or an RTX 40-series PC, you know the nightmare: signal dropouts, "sparkles" on the screen, or the dreaded "No Signal" message. After wasting money on "Premium" copper cables that couldn't handle the 48Gbps bandwidth, I bit the bullet on this RUIPRO Fiber Optic 15m version. It is worth every penny. ​Performance: The 48Gbps Acid Test ​I ran this from a PC in my office through the ceiling to an LG OLED in the lounge. ​The Results: It handles 4K@120Hz with HDR10+ and VRR (Variable Refresh Rate) perfectly. I’ve had zero flickering or black screens, which is common with cheaper cables at this length. ​eARC Support: Plugged into my Sonos ARC, it passes Dolby Atmos (TrueHD) without any sync issues or lag. ​Latency: Since it uses light (Fiber) rather than electricity (Copper) for the data, there is effectively zero lag. For competitive gaming, it feels identical to a 1m cable. ​Build & Installation (Crucial Note!) ​The cable is surprisingly thin and flexible—much easier to snake through conduit than the thick, stiff "braided" copper cables. ​⚠️ IMPORTANT: This is a directional cable. One end is marked "Source" (goes into your PC/Console) and the other is marked "Display" (goes into your TV/Projector). If you pull 15 metres of cable through a wall backwards, it will not work. Check the labels twice! ​Why Fiber? ​At 15 metres, copper cables suffer from massive signal degradation. Fiber optic converts the electrical signal to light, meaning you get the exact same bit-perfect quality at 15m as you would at 1m. It’s also immune to electromagnetic interference (EMI), so you can run it near power cables without getting screen noise. ​Final Verdict ​Pros: Guaranteed 48Gbps at long lengths; incredibly thin and easy to hide; full support for HDMI 2.1 features (VRR, ALLM, eARC). ​Cons: Expensive compared to copper; directional (don't plug it in backwards!). ​It’s an "install and forget" bit of kit. If you are setting up a high-end home theatre or a long-distance gaming rig, don't risk a cheaper cable
