10K 8K HDMI 2.1 Cable Fiber Optic 3.3ft, 48Gbps Ultra High Speed HDMI Cable 8K@60Hz 4K@120Hz, Support eARC RTX 3090 HDCP 2.2&2.3 Dolby Compatible with PS5, Xbox Series X, Roku/Fire/Sony/LG CX

I got this 50 ft hdmi cable to project to a second screen when I am delivering workshops/training. I was skeptical that it would get the job done with how thin it and small is. It's around the size of a round shoelace... I'm happy to report that I was pleasantly surprised. For my application -- sending an image from a computer to a projector -- this works perfectly. it's also small and lightweight enough that at 50 ft long it's still plenty light and small enough to keep in my work backpack. I'm very careful about the way that I wrap it because the last thing I want to do is break the fiber optic "glass" inside but other than thoughtfulness around wrapping, there's nothing else to worry about with this cable. I haven't used it for high speed applications but the image I'm getting is great. I love that this cable is long, light, compact and inexpensive! Would buy this again.

I've had this for over a year now, and it's still going strong, despite running along the floor and getting bent constantly and occasionally stepped on.I have it running from my PC with an RTX 3070 to a Sony A95K, and it *does* work with 4k@120 with either the VRR or Dolby Vision enabled (my TV support both). I've had some issues but they seem to be more related to the TV.Other reviews are rating it 1 star for not working under various conditions other than direct from Source to Display, however in testing other HDMI over Fiber cables (I work for a national A/V Integrator) I've found issues like that to be fairly common unless you're using a Balun style extender (with a transmitter and receiver over CAT6)

I was having issues with my RTX 3070 TI's display and my LG C2 OLED TV that I am using as a monitor. The signal would occasionally drop out, turn black or static for a moment and then come back. This was happening with two different cables. I figured it was likely the card or the TV, but before I went too crazy I decided to give a fiber optic cable a try and this one was among the most affordable for a 10-foot cable. Since plugging it in, I have yet to have a problem. It gives me clear 4K resolution at 120Hz with HDR on my Windows 11 PC and my LG C2. I'm very happy, great quality at a great price.

absolute garbage, stopped working after a monthno way to contact supportI get random black screens every 10 minutes

Although I cannot test their 8k capability, they work perfectly in my 4k HDR system and are priced much less than many other like cables.The HDMI connectors are plastic and, although I would have liked to have seen metal, the seem well made.

Seems like a good product. I do not notice any loss of video resolution, despite the long length of the cable

Great product would recommend

I've purchased about 6 of these cables in multiples sizes ranging from 16' to 66'. They're awful. Very poorly constructed. Once you run the line it's a gamble whether you're going to get 2.1 HDMI speed. I've had to return 4 out of the 6 these because they stop transmitting 2.1 HDMI signals.DON"T risk putting these in walls to be finished. Youll be very disappointed that you did.
