RUIPRO 8K Fiber Optic HDMI 2.1b Cable, 48Gbps, 8K60, 4K120, HDR, eARC, 10FT

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

Great deal on a great product. Nice warranty (that I hope I don’t have to exercise); glad it’s there!

Worked great for 6 months, and then failed miserably. No picture, and seemed to be sending weird signals to my amp. Put a different cable in and all problems were fixed. Very disappointing as I'd run this thing through a wall.

This cable is great, I managed to hook up my pc to the tv on the other side of the room… until it started artifacting and disconnecting after a few minutes of use. So the cable was shot. Instead of returning the cable because that would be out of the way, I heard their customer support was great, so I sent out an email and after responding to their initial response, zero hesitation they sent out a new one and it came the next day. Replacement 100% works. 10/10 cable and customer support. Maybe not so much the first cable. Would order from them again knowing they stand by their warranty

Amazing manufacturer customer service! Had an signal issue with the cable, but Ruipro Customer Service took care of the matter and even followed up several weeks later to make sure the replacement was working well.

Good

My old Apple-certified Belkin cable broke due to me moving the TV so I was finding a replacement. This one looked good and it is, indeed, good. It's good even with bandwidth-sensitive AppleTV. It's a big pipe and had no issue with high-bandwidth transmissions. One thing, though, during installation, make sure you read the label on each end of the cable {Source, Display}. The cable is one-directional ONLY, so it needs to be connected correctly or it will not work.

Updated to 3 stars. Company reached out and offered a full refund. I bought a replacement cable and had similar issues, despite being directly plugged into the receiver and the projector. Right now it shows weak signal but works, same as the old cable. Hopefully it doesn't degrade like the last one. Original: Item worked great for the first month I had it. Within the last few days, the signal seems to have gotten weaker. First it started with display issues on the projector, and I had to downgrade the HDMI port from enhanced to standard. Now every few minutes I get a brief black screen. For the money spend on this cable, didn't expect to have so many issues with it. The most recent development is now I have to reboot my input device to get the image to show. I have the image split to the projector and another monitor, the monitor works fine with no signal issues, just the projector seems to be the issue with this cable. Using the Visionmaster Pro 2 projector

Das Kabel funktioniert sehr zuverlässig. Bei mir überträgt es ein UHD Bild mit 120Hz, GSync und HDR vom PC zu einem 65" OLED LG Fernseher.

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.

PC will not boot when this is plugged in. Works fine with the other HDMI cable to the same device.

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
