I purchased this cable (probably like many of you) because it was represented as Fibre Optic ..but simply it is NOT fibre optic ! There are several tell tale signs (once you know) ..the most obvious being is HDMI Fibre Optic cable transmission is only 'one way' (so if you can use both port ends of the cable as the source or display, then it is a copper cable, NOT fibre optic) ..the port ends should be stamped as Source or Display, and will only work in that connection direction ! I also received a 3' HDMI cable (same brand advertised optic fibre cable) a couple of weeks ago ..this started my doubts & Optic Fibre research, and hence this cable is also NOT fibre optic ..I had discussed this with Amazon, but they are not able to get a response from supplier BIFALE to confirm or otherwise the construction of this cable. Their best suggestion is to return for refund (delivery several weeks from USA to Oz) so a return & refund may be awhile off yet (?) ..my desire is replacement 'real fibre optic cables' especially the 3' cable as I gave my old copper cable away (need a cable to utilize my important continuous connections) so don't know where to from here (?) ..think you guys may also now be seeking a genuine fibre optic replacement or a refund ? Disappointing that a supplier mis-represents (advertises) their products ! Now usually I give Amazon a good wrap on their delivery etc, but the wheels really fell off their tracking system for both the cables above ..both were ex USA, whilst the 3' cable arrived in 3 days at Melb. (Oz) and the 6' cable arrived from USA & despatched to courier in Oz the 7th Dec, thereafter no tracking updates (I enquired unsuccessfully with Amazon & its Courier as to cable whereabouts) ..then suddenly it arrived into Adelaide (Oz) 17th Dec, so some 10 days after arrival into Oz it still not looking like finding its way to the Gold Coast (?) ..but I must say from the outset @ ordering the anticipated delivery date was 21st Dec, and surprise it arrived PM 20th Dec ..so Amazon was true to their word, but would've liked to have received it the some 13 days earlier when arrived into Oz, especially considering the product issues re replacement or refund.

HP 8100 Elite I5 3400, 8 GB RAM, 512 SSD, AMD Radeon 550 RX 2 GB (low profile) - Integra DRX-4.2 (Refurb), 4K/60Hz/4:4:4, 7.1 - LG 65" 2018 Model. Reading forums and other manufacturer reviews; many individuals were having audio cutting out randomly. No picture issues, but only audio. This wasn't limited to my setup and I saw other people reporting the issue with Blu-Ray players, Firesticks, Xbox/PS4, and other connectivity mediums pushing 4K content. Previously I was running some newer GE cables that were for 4K capable. Older 1080p HDMI data transfer rates were up to 10 Gbps, and for 4K in the US, it was bumped up to 18 Gbps. With my PC running 4K/59-60Hz/4:4:4 and 18 Gbps cables, I would experience drops every 10 to 20 minutes (Netflix, YouTube, Vudu). If I dropped my chroma sampling to 4:2:2 or 4:2:0 or dropped my framerate from 59/60hz to 29/30hz, I wouldn't have any audio drops. Meaning, audio bandwidth was maxed out somewhere over the video signal and that those audio packets were dropped, therefore no audio was sent (cut out). The fix; higher bandwidth cables - 48 Gbps. 2.5x bandwidth per channel. I have everything maxed out and haven't experienced any problems whatsoever. For the price, you can't beat these cables either.

Ordered three of these because I was installing them in the wall for a TV installation and made the mistake of not testing them. I understood them to be backward compatible with older HDMI. Apparently they are not. I wasted two days of installation and now I am pulling them out of the wall to install HDMI 2.0 cables. Of course, I did not get around to the installation until the return window had closed so I'm just out 100 bucks. That part is my fault. But the fact that these don't work with anything in my home, and I have tried EVERYTHING, well that's on them. Don't buy these. I thought I was preparing for the future. I think I'll read a book.

Ordered these for my new 4K TV and they arrived the next day. The only thing that isn't completely accurate in their description is that I ordered the 6ft cables and they're technically 1.8 meters (5 ft 10.866 inches) which really isn't a huge deal, but if you are needing more length then I'd go up a size. The cables themselves are high quality and they're packed in individually sealed pouches. I got these on a recommendation from a friend who works in the tech industry, and I'm glad I bought them

good
