Fiber Optic HDMI Cable 50ft, 8K Long HDMI 2.1 Cable, Ultra High Speed Fiber HDMI Cord, 48Gbps, 8K@60Hz 4K@120Hz, Dynamic HDR, eARC, HDCP 2.2&2.3, 3D, for HDTV Monitor Game Laptop Xbox PS4/PS5

I got this cable so I could use my computer across the house in the living room with our LG C1. I have an RTX 3090, and it easily handled 4K at 120Hz. A quick tip: make sure you set the refresh rate in the Nvidia control panel under PC resolution settings—by default it picks the TV resolution, which won’t let you select 120Hz. After changing that, everything works perfectly.I also use a USB-over-ethernet extender to control the computer remotely, and the cable performs great with zero signal issues. Overall, it’s a solid HDMI cable for the price—highly recommend if you want a reliable 4K 120Hz setup.

Super quality works great

Working good as advertised, nice quality pictures, worth to buy. Pay attention to the direction of cable. This cable is only 1 way signal.

7/1 - These seem to be excellent HDMI cables: My old cables were stiff and not very flexible. THese fiber cables are thin and quite flexible, though you don't want to crimp them unnecessarily. Just be sure you plug the "SOURCE" end into the player or device that provides the HDMI signal and the other end labeled "DISPLAY" into the projector, monitor or other display device you're using.In terms of stated specs: I tested these cables with a HI-Sense 4K TV using an OPPO BD-205 (top of their line) Blu-ray player and my TV did not report any issues. I will be testing with a 4K HD projector and will update this review as necessary. But as of now, these are excellent HDMI cables IMO.7/2 - I tested a 50' cable with an Optoma HC-4400 Pro 4K projector and the 50' cable seems to have worked flawlessly. Picture quality was outstanding, no drop outs, or other issues. I used the eARC HDMI input on the projector which has speakers, and the sound was plainly audible with no distortion. So, these seem to be exceptinally good cables for HDMI.I will no longer purchase copper-based HDMI considering these fiber cables are outstanding and quite affordable.

THIS IS A DIRECTIONAL CABLE MAKE SURE YOU CHECK WHICH END IS SOURCE/DESTINATION.I thought mine didn't work, it works fine. Just not used to "Directional" HDMI cables...

This 15 foot cable worked as an eARC cable when another brand's 15 foot cable didn't. The other brand I used was just a normal HDMI cable, not a fiber optic one. This fiber optic cable worked.I'm using it for my TCL 98 inch TV (98QM850G) to output audio through the eARC HDMI port (4k/60Hz) to my Sony AVR (STR-AN1000). Originally, I tried a 15 foot ARISKEEN HDMI cable ( https://www.amazon.com/dp/B0CW9M8FDS ), and that HDMI cable dropped audio every 30 seconds or so for one second. It wasn't able to keep up with the audio for some reason. And because it was a lengthy cable (15 feet), I decided to try this 15 foot fiber optic HDMI cable, instead. And it worked just fine! No problems with audio.I don't know if this one will last a long time. There are obvious electronics inside of the cable that convert the digital electrical signal into a fiber optic light signal. So, I assume the electronics will wear out eventually. I wish a passive HDMI cable would work for 15 feet, but it's a total gamble out there right now whether you can get a cable that actually works or not. Most of the cables out there are just junk. They sell themselves as wonderful, having super high specs. But they don't work. So for the moment, this HDMI cable works and seems solid. We'll see if it lasts.

Sent this 25ft cable through my wall and had no issues plugging it in and having it work flawlessly first try. I am able to achieve 4k144Hz without any issues.

Cost effective cable getting stable 4k 120hz on my TV! My old 2.0 cable had screen tearing at 4k 60fps, but this let me double my refresh rate and solve my screen tearing problem!
