GeoHN.G 8K Fiber Optic HDMI Cable 10M, Certified 48Gbps High-Speed HDMI 2.1 Cable, Support 8K@60Hz 4K@120Hz/144Hz eARC Dolby HDCP 2.2&2.3 HDR10 RTX 3080, Compatible with PS5/TV/Xbox Series X/PC

The hdmi was working great on my pc until it died randomly. At first I thought maybe it could be my pc so I tried it on multiple different devices and no picture at all. This lasted me 3 days that is incredibly poor

Im using as a secondary cable for 1440p signal bypass for audio. Works so well I'm using as the video signal and my old HDMI connected to my AVR. (AVR's don't support 1440p signal-even in bypass passthrough). Very thin cable, thin enough for walls but thick enough to not break easily. Very impressed actually, I'll buy again for other long lengths rather than super thick all copper leads.

Had this cable for just over a month for connection from av receiver to projector which are both 4k. Had quite a few issues with connected devices the main one being nvidia where the signal was constantly being lost to the point where there is now no picture at all...regardless of what settings are used. I am very disappointed with this cable considering the main reason for the purchase was that it is supposed to be a certified cable?

Bought this following a projector upgrade that needed a long HDMI cable run to send a 4k signal after trying a couple of non-certified cables that failed to work. It's nice and thin, flexible and easy to install, especially if you need to get around corners. The price was very attractive, being the cheapest certified cable available at the time. It worked fine for around two months, although there was the occasional couple of seconds dropout - these were infrequent (maybe once or twice in a week). However, the cable has now failed completely, and won't send any signal through at all. Disappointing and now I have to find another cable to try.

Runs at 4k120 with HDR 12 bit G-sync. Couldn't ask for more. Good value for a certified cable.

Worked well for a month then suddenly stopped. PC and monitor detect the cable is plugged in but will only display a black screen. Tried on a different device, same result. Tried a different cable and that works fine so clearly something has gone wrong in the cable. It failed 2 days out of the return window, would not recommend it.

As I would expect from a fibre optic cable, signals are transmitted over a long distance without any lagging or interference. The plugs fit in correctly, but be aware that they are uni-directional. What worries me about this cable is how remarkably thin it is. It will need to be well protected all along its route to avoid a fatal breakage.

Using for 4K 144hz from computer to Samsung S95c television, worked flawlessly for first three days, then suddenly would not pass signal to the television at all; not even used for gaming but just web browsing and watching 4K content.

I have been upgrading my entertainment system from 2K to 4K slowly over the last two years. The last thing will be to replace the Epson Home Cinema projector, which started experiencing periodic video dropouts. Suspecting the old 30 foot 2K cable (HDMI 1.2) was an issue, I bought this one to be able to support a future 4K @ 120 Hz projector. So far, no more issues with video dropouts. Also, I am seeing a more stable video image. I can't wait to see how good a new 4K projector looks!

Zero star if possible. Broken after a month. Rarely used.

Rating: ★☆☆☆☆ (1/5) Absolutely terrible experience with this seller. The 8K Fiber Optic HDMI Cable (33ft) never worked. I was promised a replacement, which never arrived, and I never received a refund. This is outright scam behavior. Buyer beware—avoid this seller at all costs.

c'est le deuxièmes que je commande,pour relié ma ps5>avr demon>tv. fonctionne très bien qualités du son 7.1 atmos 👍 et meilleur qualité de limage 👍 de plus hdmi fibre optique~certifié~. vous rechercher un hdmi a un prix resonable? et bien cherché plus c'est ce lui ci qui il vous faut. je vous le conseil.

Für reine "Video Übertragung" in 4k ganz OK. Wer jedoch auch noch Mehrkanalton wie Dolby Atmos oder HD Masters Audio übertragen will, wird damit nicht zufrieden sein. Bei mir habe ich sehr starke Ton Aussetzer. Das Bild hingegen bleibt immer stabil. Ich nehme an, dass nur der Videokanal mittels Glasfaser übertragen wird. Das Kabel ist sehr dünn. Dadurch wird die Kabelabschirmung der Audiokanäle darunter leiden, falls überhaupt vorhanden! Bei FireTV streaming keine Probleme. Funktioniert jedoch bei unkomprimiertem hochqualitativem Audio z.b. über Kodi nicht gut! Update 17.7.2024: Nach wenigen Wochen ist das Kabel nun defekt. Ich vermute das die integrierten LWL Chips tot sind. Bekomme kein Bild mehr zum Projektor. Schade. Muss ich leider reklamieren.
