GeoHN.G Fiber Optic HDMI Cable 33ft, 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 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

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.

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.

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.

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.

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

While I was I bit put off by the aesthetics and at this price point these cables are a bargain. When I got my 4K 120hz capable TV for my bedroom I wanted to minimize the need to purchase and rerun anymore cables through my conduit in the wall. I hastily bought four ZenDesk ultra certified cables at approx 16ft to cover all inputs in the TV. They worked pretty well but they were somewhat thick and far longer then I needed; creating a nest of cables. I decided that 10ft was far more suitable. These being MUCH thinner made running all now five cables plus Ethernet (3 for the TV and two for the soundbar) a pleasant experience. All my cables worked flawlessly with all of my inputs. Generally no issues with my 3090 running 4K 120 with HDR despite having a passive right angle extension between it and this cable.

I love how thin these are and video is great with these. So far no issues whatsoever with video, eARC on the other hand is a no go with these. It worked fine to start with but after like two days sound just started breaking up until it finally just stopped come out of my sound bar. Switched back to my original cable for my sound bar and it started playing again.

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

Acabado del cable y flexivilidad muy bueno.

I was concerned about possible latency and HDMI plugs overheating, however I needn't had been concerned. Not even warm to the touch, and no real-world latency, i.e. well below 1ms. This cable just delivers what it promises. Copper cables tend to be device sensitive, for example even if the cable is certified, it may not function correctly with some devices at high bandwidth due to any number of issues such as HDMI port quality (the receptacle that you plug the cable into, both ends). Many of the HDMI switches tend to have compatibility issues because they tend to use rather cheap physical HDMI ports. Even the latest TVs have been noted to skimp on port quality (one could argue it is to help bring prices down, some would argue it is about keeping profit margins high and not the presumed assumption of bring consumers lower pricing). I would recommend to nearly always try a good quality copper cable (certified), because you save on a little bit of electricity (less than a watt for these HDMI optical cables), and if you can get away with traditional copper cabling, great, but only resort to optical cables when coppers just don't give you what you need with your setup. Indeed for longer runs it is always better to go with optical for high-bandwidth requirements. This cable is good, rather flexible slim cable. I wouldn't recommend this cable for tasks where constant removal and plugging is part of the job description as they are not built like the heavy-duty monster copper variety designed for 'military style' handling. This cable doesn't have any strain relief, it has just a short gland at the rear of the plug which is clamping the cable into the plug, to be honest it is all you need as the cable is quite flexible, but this isn't the type of cable where you would constantly pull on the cable itself, unplugging by pulling on the plug rather than cable is advisable for a cable of this design. Happy with the cable, if you're looking for upto 8K 60hz bandwidth support, this one is a bargain.
