8K HDMI Ultra High Speed Latest 2.1b Certified Fiber Optic Cable CL2 Rated 50 Feet 8K60Hz 4K120Hz 48Gbps eARC HDR HDCP2.3 for RTX4080/4090/3080/3090 Xbox PS5 AVR Projector LG/Samsung/Sony

I’ve been disappointed in the past by two other brands of optical HDMI cables that developed flickering after just a few months. RUIPRO came highly recommended on forums, and while it’s priced at double the others, the build quality is unmistakably superior. The cable is noticeably thicker than the last ones I had, the connectors stay far cooler, and the overall feel is much more robust. It also comes with a lifetime warranty from a company that’s been around for years, giving me confidence it’ll be honoured if something ever goes wrong. So far the cable performs flawlessly with my TCL C7K TV and an RTX 5070 Ti: I get ALLM, VRR at 4K 120 Hz with HDR and full 10‑bit colour depth without any issues. Time will tell if it continues to hold up, but for now it’s delivering on its promise.

Funktioniert einwandfrei auf 15M Länge an einem Sony Bravia 8 Projector ohne Signalabfall, musste von einem 12GBit Glasfaserkabel (8 Jahre alt) auf dieses umsteigen.

Got the 15m variant. The only cable where I could get 4k UHD HDR 4:4::4 @ 120hz. Not a single drop in months

First off, this works fine for me at 4K 120Hz HDR with VRR. I can't comment on ARC or CEC however since my use case is from a PC. My only gripe is that I was expecting a thin smooth cable like the one pictured, but received a very substantial "ribbed" one instead. When cables of this length are often going to be buried in walls or in conduit, the thickness and ease of pulling through is a very important consideration, and I don't appreciate the misrepresentation, especially at this price point.

J’ai acheté ce câble en version 15m gen3/c certifié UHS HDMI 2.1b afin de relier mon vidéo-projecteur à mon ampli AV. Le vidéo-projecteur étant connecté avec des applications de média player intégrées, j’ai besoin d’utiliser le canal eARC afin de renvoyer le son vers mon ampli AV. Malheureusement, bien que ce câble soit certifié HDMI 2.1b avec eARC, l’audio en eARC est inutilisable avec des coupures du son permanentes. J’ai dû désactiver eARC pour utiliser ARC à la place mais les formats audio non compressés ne sont pas supportés en ARC. La vidéo dans le sens ampli AV -> Vidéo-projecteur fonctionne bien par contre. J’ai testé jusqu'à la résolution UHD HDR 50p sans problème et le test du câble par mon ampli Denon donne bien 40 Gbps de bande passante.
