DGHUMEN 8K Fiber Optic HDMI Cable 10M, 48Gbps Ultra High Speed HDMI 2.1 Cable Support 8K@60Hz 4K@120Hz HDR eARC 3D Dolby Atmos HDCP 2.2/2.3 for Gaming Console/Projector/Television/Monitor/Laptop

My initial review for this was negative because the cable didn't work despite all of my troubleshooting, so I'd committed to just getting a refund. The seller reached out and asked if I'd be interested in testing a replacement, so I said yes. I was surprised when I got a knock on the door the same day with a replacement item that worked the first time.The cable is soft and has good flex, but can be shaped, which is important with fibre cables, as you want to avoid sharp corners wherever possible.I can't test the 8K claim, but it did 4K at 144Hz with 12-bit fine, which should require slightly higher bandwidth than 8K at 60Hz anyway.

Specs are as advertised. I've only opened 1 but it worked perfectly. You should note that its single direction so there is an end for the source and an end for the display. I specifically needed just shy of 15m so I can confirm that the length is as advertised. Product looks to be pretty sturdy compared to some of my previous HDMI's.

I'm referring to 10m long versionArrived on time, nice packaging, premium looking product, but unfortunately this is the end of excitement.For the avoidance of doubt, my other,shorter hdmi cables works perfectly in the below mentioned setup.Setup: Nvidia Shield Pro -> HT7000 (eARC) -> 4k Xgimi10m long version does not send 4k signal to a 4k projectorI decided to connect Shield -> projector (with spare hdmi cable) and from xgimi (eARC) -> Sony HT7000 (just pass through lossless ThrueHD audio), does not work as well.So, with my tests, this cable does not support 4K + Audio, 4K alone and audio aloneAlready started refund process

Unlike most HDMI cables, you need to connect the cable from your source into your display, as labelled on each end or it won't work. I've got it connected from a Windows Gaming PC into a 4KTV running at 120Hz. There has been no issues at all, no flickering or anything like that. Works great. Recommended.

This works great, connecting my PC that is 15m away from my TV (4k 60hz, 85"). Since my PC was above my living room, I was able to use my Bluetooth devices to control it with no issues.

I purchased four 15m fibre optic HDMI cables, each claiming to support 48Gbps speed and eARC capabilities. After thorough testing, I discovered that while this cable does deliver on 4K at 120Hz, it disappointingly falls short on its promise of eARC support.The four cables I tested are:FIBBR 8K HDMI Fibre Optic Cable 15M, 48Gbps 8K HDMI 2.1DGHUMEN 8K Fibre Optic HDMI Cable 15M, 48Gbps Ultra High-Speed HDMI 2.1BlueRigger 8K Fibre Optic HDMI Cable 15M (48Gbps, in-Wall CL3 Rated, eARC, 8K 60Hz)Cratree 2.1 Fibre Optic Cable 15m 8K - 48Gbps Ultra High-Speed Cable Support 8K 60HzOf these, only the Cratree cable actually supported eARC as advertised. If eARC is a crucial feature for your setup, I would recommend looking elsewhere or opting for the Cratree model.

Works most of the time but periods of intense flickering (usually resolved by unplugging and reconnecting) rainbow type effects and sometimes it just refused to connect without multiple restarts of PC and monitor.This seems to be solid at 4k 60hz, had all of the above issues at 120hz 10bit colour. Replaced with another brand which resolved all of these issues (it had an additional USB powered adapter which may have done the trick).

Not good second day was not working
