GeoHN.G Fiber Optic HDMI Cable 24ft, 48Gbps High-Speed HDMI 2.1 Cable 8K@60Hz 4K@120Hz Dolby/Dynamic HDR/HDCP 2.3/eARC 8K Fiber One-Direction HDMI Cord Compatible with Blu-ray/TV Box/HDTV/Projector

I recently purchased the GeoHN.G Fiber Optic HDMI Cable (24 ft) and am extremely satisfied with its performance. The build quality is impressive, with sturdy connectors and a robust cable that feels durable but like all fibers be careful with it and do not bend it too much or crush it. I’ve used it to connect my gaming PC from one corner of my room to another. The cable delivers clear, vibrant, and smooth visuals. The one-directional design is clearly marked, ensuring easy setup. Overall, this HDMI cable offers fantastic performance and value for money compared to others. I recommend it for anyone looking to upgrade their home theater or gaming setup for long distances without impacting performance. Let me just add that I haven't tested the 4K@120 since my TV is 60hz

This is the best of all the cables that I tried to get to split a 4K 120Hz signal from one source to two displays (one at a time) through a switch/splitter. I had to return every other cable including other fiber cables. The splitter I’m using is the IVANKY 8K switch And it said not to exceed 5ft of cable in either direction but I have a 3ft cable from the source and a 15ft from the switch to one of the displays and there is no issue. Nothing else worked reliably.

I had a problem using traditional HDMI cables with my LG C2 OLED TV that I use as a monitor for my PC. The signal would drop out fairly frequently somewhere between my RTX 3060 Ti graphics card and the TV. When I switched to a fiber optic cable, the problem went away and hasn't returned for 2 years now. I just purchased a soundbar that I wanted to use its HDMI pass-through on it, so I needed a second fiber optic cable and decided to try this brand. This cable is working perfectly and it was a good value compared to others for the same length. I now have perfect video quality and amazing sound and this cable helped put everything together.

Look, I'm not going to fall into the endless rabbit hole of HDMI and if at the end of the day it's just a question of one's and zeros and nothing even matters anyway...lol I used a pair of these to connect my 4k player to a 2.1 port on my TV. Afterwards I could swear there was an increase in volume. Make of that what you will.

Works fine on my LG C2 at 4K 120Hz. However, does not work on my 45GR95QE-B at 3440X1440p @ 240Hz. Both my GPU (4090), display, and this HDmI cord are HDMI 2.1 compatible, so getting 240Hz at 1440p should not be an issue. Ended up swapping out this cable for a different HDMI 2.1 cable and am now getting 1440p @240hz no problem. Stay away from this cable if you are a PC gamer.

Fiber optics avoids two issues with traditional cables: 1) Electrical noise 2) Electrical Capacitance, which limits the frequency, i.e. RC timing issues The cable is small and very flexible. The ends do plug snuggly into the HDMI ports. This would be about all that could be reviewed regarding a cable, but this cable is a fiber optic cable, which means it uses light to send the signal the length of the cable. Fiber optic cables can run much longer distances without the same problems as electrical cables. This means you can have your display in one room, and the source electronics in another room for whatever reason (security, climate controlled, aesthetics, etc.). It used to be that display cables were limited to much shorter distances. It is finally nice to have fiber optic cables at a reasonable price. For example, Samsung has a fiber optic cable that is proprietary and costs $300. Pay attention to the Source and Display ends of the cable. This is important because each end has a directional controller chip that processes the signals and a SerDes chip to send the signal down the cable. In this case there is also photo electric chips that convert electric signals to and from light signals. It's pretty amazing how much electronics are just in the connectors of each of these cables. This is being used on a 8K display, so only time will tell if the 16K capabilities are real, however 4K@240Hz working should give some confidence that 16K@60Hz will also work. PROs: + Solid metal connectors + Small flexible cable + Long length + Price CONs: - Connector color

Didn't know fiber optic hdmi was even a thing. Just built a pc and running it to my sony 55" TV.. it would flicker.. I've gone through like 5 different cords. And this one right here is the one that fixed my problem. No flicker, running at 4k 120hz HDR. I could kiss ya 😘

I purchased the 50 foot version as I needed an HDMI cable of that length to run from my computer (2080Ti graphics card) to my TV on the other side of the room. The only way to get an HDMI to the TV would either be a direct run of 20 or so feet in the center of the room or make it run the perimeter and try to do it cleanly. I chose the latter. This cable has about the same thickness as a standard usb charging cable so makes it very easy to hide and bend around corners. I received the cable this morning and have been using for the better part of the day now and no hiccups in signal. Exactly what I was looking for! Just remember to hook the cable up in the right direction, as it's a directional cable, the heads are clearly labeled to tell you which way to connect.

Bei cavi, tutto dipende dal prezzo a cui li comprate. Il cavo in fibra occupa meno ma è chiaramente più delicati e i connettori più ingombranti in profondità.

Purchased three of these cables for sending 4k @ 120hz over long distances. Tried two other brands. These all work flawlessly

à trois reprises j'ai acheté ce HDMI en fibre optique après quelques heures de fonctionnement l'écran était noir si vous ne voulez pas perdre de l'argent je vous déconseille ce produit heureusement amazon est intervenue et à rembourser les produits défectueux encore un grand merci à Amazon pour son travail et son honnêteté

Très bon câble HDMI, excellent rappot qualité-prix!

Go no further. Works perfectly for the right price. Does what it says on the tin, functionality 5/5. Edit: I am very happy to report that the smell issue I reported below was temporary and has resolved completely within a reasonable amount of time (days-couple weeks). The cable in the meantime perfoms FLAWLESSLY for months now. Updating to 5/5. It is quite light, narrow and thin, and as flexible as you can expect a fiber to be (it comes i a package wrapped in a 10-15 cm diameter loop, I'd trust it to do corners as tight as 3-4cm radius). It's not copper of course, and I wouldn't expect it to be. So far 5/5. I tried it at 15m - 4K/120Hz, spliced to an 8K rated adapter and another 8K rated 0.5 m copper cable, and it works just fine even with these on top. 5/5 still. However, there is one thing I never expected to say in a review of a cable: It smells horribly of elastic! (neoprene? latex? something else?) Every time I touch it (it's not permanent for me), this smell lingers on my hands and I need to immediately wash them XD XD XD. I can smell it from a distance of ~1m away. I will try to wash it with a damp soap-and-water cloth or something else to get rid of most of the smell, but that's seriously strange. Edit: Don't think I'm someone that hasn't handled a cable before in his life, I have more than 100 m of cable lying around and in boxes for multiple installations, engineer, doing my own cable installations at home, etc. What I am describing is Something Else (TM), I think the sleeve is something close to neoprene. Washing helped 50%, still leaves lingering smell on the hands. I really hope it goes away with time. (EDIT: It did :) )
