Fiber HDMI Cable 25ft 4K 60Hz, FURUI Fiber Optic HDMI 2.0b Cable HDR10, ARC, HDCP2.2, 3D, 18Gbps, Subsampling 4:4:4/4:2:2/4:2:0 Slim and Flexible HDMI Fiber Optic Cable

An HDMI Cable That Actually Passes True 4K HDROn March 22, 2019 I purchased a 25’ FURI fiber optic HDMI 2.0b cable to connect my Onkyo RZ820 receiver to my Vizio P75 TV mounted on the wall across the room which required a 25’ HDMI 2.0 cable. Connected to the Onkyo’s HDMI inputs are two 4K HDR sources, an Oppo UDP-203 Ultra HD Blu-ray player and the Amazon Fire 4K TV Stick. Before I moved the receiver to the other side of the room, everything worked perfectly with a 10’ High Speed HDMI 2.0, HDCP2.2, 18Gbps cable.When you are using relatively short cables, 15’ and under, the length of the cable will usually not cause noticeable signal degradation and some even say you can go up to 20’. I have tried several 25 and 30 foot cables including the Monoprice High Speed Active HDMI Cabernet Ultra Series, a High Speed HDMI cable by KabelDirekt and this cable and none managed to fully support full 4K HDR with Dolby Vision. I returned this cable, posted a review and the company contacted me immediately wanting to know a bit more about my issues with the cable. After a brief exchange of letters they sent me a replacement cable and I have to say it is working perfectly for several weeks now, the picture is gorgeous. Watching “The Expanse” in 4K UHD on Amazon Prime looks great and “The Gladiator” in 4K HDR/Dolby Vision on Blu-ray looks spectacular!The first FURI cable had “handshake” (which I explain below) issues with my receiver which did not allow it to pass the video signal when I enabled Full UHD on my TV while the replacement cable had no such problem. The new cable works as advertised passing 4K @60Hz with full HDR including Dolby Vision from the Amazon Fire TV 4K as well as 4:2:2 and 4:4:4 from my Oppo UDP-203.What I also appreciate about this cable is how thin and flexible it is. By not having to use heavy gauge wire to carry the video data substituting thin fiber optic cables instead, this cable is very easy to work with and especially easy to hide in narrow channels. Be careful not to pull/stretch it or bend it excessively as you could damage the very fine fiber elements inside it. FOR THOSE WANTING TO KNOW MORE ABOUT HDMI CABLES, 4K AND HDR CONTINUE READING…..When I was first shopping for an HDMI cable, I really didn’t know what all the numbers and specifications meant and why they mattered. Here is a brief primer to help you understand what it all means.4K refers to how many pixels are on a screen while HDR (High Dynamic Range) indicates the range of brightness to darkness that those pixels can cover either by having brighter highlights, darker black areas, or a combination of the two. UHD or "Ultra-High-Definition Television" is an industry specification that combines the two (plus some additional features) into an easily recognizable term.Consumer video is stored, transmitted, and processed in a color space called Y’CbCr. The three components stand for: Y’ = Luminance, or brightness of the pixel, Cb = Blue color difference andCr = Red color difference. There are three main types of color subsampling used today. These are 4:4:4, 4:2:2 and 4:2:0.If 4:4:4 is a full bandwidth signal, then 4:2:2 occupies 2/3rds the space and 4:2:0 occupies 1/2 the space. Blu-ray and UHD Blu-ray both store the video signal in the 4:2:0 format on the disk. When that disk is played by the player, it is upconverted to 4:2:2, which is sent through the HDMI cable to the display which upsamples the signal to 4:4:4 and converts to it RGB. Why does the display do most of the upconversion (4:2:2 to 4:4:4 to RGB), this reduces the HDMI bandwidth requirements. If you have a Home Theater Receiver between them, it just passes the signal though some may process the signal if your player or TV can’t perform this function.There are several types of HDR formats: HDR10, HDR10+ (Samsung’s answer to Dolby Vision), Dolby Vision and HLG. All “HDR” devices support HDR10 while support for the other formats is manufacturer specific. Right now, virtually all companies also support Dolby Vision and HLG with only Samsung refusing to do so. As their Blu-Ray players only supported HDR10, sales were mediocre and as of February, 2019, Samsung says it won't produce any new 1080p or 4K Blu-ray players for the US market.Dolby Vision seems more focused on pushing HDR to its technical limits than HDR10. Dolby Vision uses frame-by-frame metadata (Metadata is data sent along-side the image portion of an HDR signal that gives the monitor extra instructions about how to display the video adjusting brightness levels and color range) to manage HDR performance, significantly increasing the amount of data that passes through the cable. Dolby Vision content is mastered in 12-bit color depth, compared to HDR10's 10-bit (which is where HDR10 gets its name from). UHD Blu Ray is also 10 bit when it reaches the display and most newer consumer TV displays use 10-bit panels.In order for this all to work properly every component in the system has to communicate it’s design parameters and capabilities so they are all on the same page which requires the exchange of metadata between them. HDMI handshaking is a process that occurs between sources and display which does just that, when it works, your video and audio signals are properly passed through the HDMI cable. Many cable “failures” are due to handshake errors which will result in audio or video signal failures.Inside every HDMI cable, there is a pair of wires for DDC - Display Data Channel (pins 15 and 16). The DDC carries two kinds of data: HDCP (the copyright data) and EDID, Extended Display Identification Data, in metadata format for display devices such as TV’s to describe their capabilities to video sources such as Home Theater Receivers, Streaming Devices, Blu-ray Disc players, and even gaming consoles. This allows the video sources to then send out a video signal that is supported by the display. If the data passing through these two wires is corrupted or under the specified voltage (5 volts DC +/- 0.3) you may not be able to get a decent picture, the correct resolution or any picture at all. So it is important that every connection inside the cables connecting your equipment functions properly. In longer length standard cables there may be a voltage drop and if it goes below 4.7 volts DC, there may be handshake issues which could impact the audio and/or the video signal as well as degrade the high data rate Y’CbCr video signals passing through them. By replacing heavy gauge copper wires with slim fiber optic conductors, signal loss issues are greatly decreased.Hopefully, this additional information will help you understand not only what the HDMI standards are but also give you better insight into how to set up your various devices.

Your browser does not support HTML5 video.  When working it provided a fantastic 4k picturewith amazing HDR. After about four months of use the audio and video started dropping out intermittently. I use this fiber optic HDMI CABLE to connect my Denon 6500 AVR to my EPSON 6050ub projector. Projecting onto my 120 Seymour Glacier White screen. Now the picture has completely stopped working. UPDATED: CONTACTED THE SELLER . They sent a new cable out immediately free of charge. Great customer service experience.

I have a 75” 4K UHD Sony XBR hooked up to a Marantz SR7011 via ARC. My previous HDMI cable was a “high speed” cable with Ethernet and it ran 50ft from my A/V components cabinet to the Sony. My picture and sound was very good, but I realized I wasn’t getting the absolute best performance out of my investment because my HDMI cable was approximately 6 years old and my Sony is 12 months old—upgraded TV and neglected the HDMI cable. So I researched more advanced HDMI cables and came across several brands with fiber optics. The benefits were what I was after, 18 Gbps, HDR10, 4K/60HZ etc. The prices for these cables range from $150 up to well over $500 depending on the length of the run. Not wanting to spend a fortune, I decided to try these cables. They arrived the next day (love Amazon shipping) and I noticed immediately the cable was very much thinner that my previous cable. Any rate, I did a “test drive” to make sure this cable performed as advertised before I commence “fishing” 50ft of cable through a wall and attic space. I was blown away with the results! Crystal clear, bright tones, rich color, deep blacks and the front sound stage was definitely enhanced—I’m finally getting the quality picture and sound my system was built to deliver. If you have A/V components that have the capability to deliver and support the latest 4K UHD technology, HDR, 2.0b, ARC, and sound, this HDMI cable will get you there. Don’t hesitate, add to your cart now.

I edited my original review, since the company sent me a replacement for my problem cable. I left my original review below so you can read in case you have an issue. The service from the company was prompt and friendly. Now I can recommend.I bought this cable to do HDR 4k for my optoma projector and all sources look great in 4k but once it goes into HDR mode I get white lines flashing across the screen on any source my Roku and my game consoles. My old cheaper cable never did this but I figured I could try what I thought was a good cable. I have been in home theater projects and systems for almost two decades and I do not recommend this cable.

Stumbled across these cables on a search for 4K. HDMI cables that can pass Dolby Vision and HDR10+. This cable CAN! I’m using it on a 35ft run from Sony tV to Marantz receiver. ZERO dropouts or any issues. I recommend this cable to anyone who needs reliability and quality for their 4K video output. Cheers

Seems to work great compared to my regular 50ft hdmi 2.0 cable. My Xbox one x couldn't fully do 4k and when I installed this is came up at 100%. I've only had a few blip issues where the screen would flash out when I started a game but it would come right back a second or two with no other issues.My other physical issue is because it is fiber it is a tiny cord which worries me if I ever have to move it elsewhere that I'd bend it wrong and "bye bye" expensive solution to my issue.So far 98% satisfied.

Purchased this 25'cable for $120 for my eARC application and the sound skips (mutes) for 2-3 seconds every minute or two. Went to the store and purchased a more expensive cable but it works. It's disappointing because the eARC feature is advertised twice on the Amazon site but when I received the product the box only says "ARC" but I found it doesn't work with that either so don't buy this if you plan on using a sound bar or receiver.
