GeoHN.G Fiber Optic HDMI Cable 6ft, 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

Perfect quality and a good price for fiber optic cables
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.

Doesnt work on PC at refresh rates above 120Hz.
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.

Works great!
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.

Great Value, Good Quality
I wanted to wire this through the wall and have it come out the back of my desk so when i want to plug in my laptop to my main monitor it looks discreet. It did just that but because the cable is more elastic than a lot of hdmi 2.1’s i can tuck it away nicely into the pouch on the side of my desk. A lot of the fiber cables on here are threaded which is nice but only if the cable is thin and flexible which most on here are not. I purchased a 50 ft one from my room where my ps5 is to the living room as well and it is still displaying 4k120. For an HDMI 2.1 Fiber Optic its one of the best since its not too thick and its not to expensive either.

Absolut empfehlenswert. Nicht nötig, das doppelte für ein 8K HDMI 2.1 Glasfaser Kabel auszugeben. Macht alles, was an Spezifikationen angegeben ist (nach einem Tag Test in meinem Heimkino mit störenden Signalquellen, langer Strecke, engen Biegeradien etc).Wer neu im Thema Glasfaser ist, dem sage ich aber noch den Standard-Text: maximale Biegeradien beachten, niemals knicken! 90° Ecken gehen, aber nicht geknickt, sondern in einem Bogen ausgeführt. Kabelkanal: ja, wenn weit genug (in den Ecken) für einen Bogen.Kabel geknickt = Faser gebrochen = Kabel Müll. Nicht machen… Nie…

I got it, it worked okay, a little sensitive/problematic if you really push it to the limits (4k 120fps with hdr didnt work that well ) but otherwise worked quite okay for the price. However only after 2-3 months of use it fully stopped working and gave me a heart attack (I thought either my gpu or tv was broken and both cost 4 figures ) but “happily “ it was just the cable. Would not recommend, as build quality or/and quality control are quite bad even for the price that it it. Either buy good quality hdmi 2.0 for same/less money or spend quite a bit more but buy a proper certified quality hdmi 2.1. The in between doesn’t work :/
