8K HDMI 2.1 Cable – 10m – Optical Ultra High Speed HDMI, certified with 0% signal loss (8K@60Hz, flexible fibre optic cable, officially licensed, lossless transmission) – by CableDirect

I purchased 15 meters of this baby and laid it down under floor beadings in a gap between the floorboards and the wall. The gap wasn't wide enough at some places so I had to squeeze down with force and also with some nasty 90 degree turns in the corners. I thought I was going to brake it keeping in mind the fragile fibre optics inside. But hallelujah, it works like a charm. So far I am impressed. Other reviewers posted that they start having problems within a couple of weeks or months with this cable and I will update back here if some problems will start showing up. Also I don't have any 4k 120hz screen yet, so can't report on 4k120 performance but 4k60hz works well without any dropouts or black screens from my PC.

Purchase this cable to connect my PC to 4K OLED TV. Perfect picture, now watching all HDR and UHD content streamed from my PC. Does the job perfectly! *****

These cables are certified and expensive. I'd expect them to work, which they do for 15 minutes at the most. I have an LG 65NANO916PA 2021, and I bought 2 of these cables to connect to PS5 and to Apple TV 4K. I use the Apple TV 4K for eARC also, and the PS5 I run at 4K@120Hz. All this worked with these cables, but I kept getting black outs. In a 30 minute TV show it blacked out 3 times, for about 4 seconds each time. On the PS5 during gameplay, it would also black out (i.e the TV went black with no signal) - which during gameplay is just not acceptable. The cables are pretty slim, I ran the 7.5m length. The connector was getting pretty hot also, so I don't know if this was related. But basically it makes them unusable with my setup. I've since bought the Cable Matters cables and they seem to be working fine so far without any problems.

Purchased the 7.5m to use with an Xbox Series X and the pic quality is excellent. Had purchased a cheaper HDMI 2.1 cable at the same length which was not certified and had a wierd issue where some live tiles were missing on the Xbox dashboard. The issue has been resolved using this cable.. I have to say I have purchased at least 8 Kabledirekt HDMi cables over the last few years and they have all been absolute quality. Highly recommended

Didn’t work with a Yamaha RX-A3060 receiver. Flickered and blacked out continuously. Yes, I did connect them the correct source/display direction. But, work perfectly with my new Yamaha RX-A8A up to 4K/60hz over a 5m run. Can’t comment on 120Hz performance until I upgrade the TV which is a Panasonic 58” TX-58DX902B. Sources are an Xbox series X and a PS5 for gaming and a Panasonic DMP-UB900EBK blu-ray player for film. Easy to run as a small diameter and flexible.

Replaced a 7.5m high speed copper HDMI cable with this fibre optic type. Straight away there was a huge improvement in picture quality and where we couldn't run Apple TV box on highest setting previously, due to signal degradation in the old cable, it is now able to run at full 4K 60 Hz. Marked improvement.

The cable works perfectly with my PC and TV. Got 4K/HDR/60Hz working in no time. The only thing better than the product is KabelDirekt's customer service. Quick to respond and extremely helpful. Recommended!

Unfortunately the screen on LG C2 42" OLED flickers often when running in 120hz with this cable, had to reduce the refresh rate to 60hz to get a stable image. The 48G rate this cable is supposed to be certified for is therefor not met. For 60hz it works fine so far.

câble de très bonne qualité. retransmission du signal vidéo et audio sur 10 m sans perte de qualité. ce câble me sert de connexion entre mon décodeur et ma Samart TV en passant par des gaines dans les murs

Świetna jakość, bardzo duża przepustowość i praktycznie zerowa podatność na zakłócenia. Nigdy jeszcze nie pojawiły się jakiekolwiek problemy lub artefakty, mimo długości 10 metrów.

Ottimo prodotto. Stabile e affidabile. Preso il cavo in fibra da 15metri con l'aggiunta di un booster lo startek 2.1 - qualità garantita! Costa un po' ma io non me ne sono pentito.

Just like other KabelDirekt productsI've used, this works flawlessly. Keep in mind that the cable must be connected properly to work, the display end must be connected to the TV or Projector. Initially, the cable did not work with my AVR, simply updating the firmware on the receiver resolved the issue. Now Dolby Vision and Atmos work without issue.
