Review: Now Works Great – Additional Info On 4K HDR For Reference - An HDMI Cable That Actually Passes True 4K HDR On 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 desertcart 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 desertcart 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 desertcart 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 and Cr = 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. If anyone has any further questions please ask. Art
Review: WOW just wow! - Ok I just bought this cable on a gut feeling and I'm not disappointed in the least bit! The colors are vibrant, incredible clarity and lag for gamers is well, no more mad button pushing! Tried the cable on three different devices AppleTV, PS4 Pro, and XBOX One and all are connected to an LG CX 65". Both consoles just were just excellent. The Apple Tv was just spectacular! I'm so impressed with the product that I'll be purchasing one more or maybe two. They are pricey, to say the least, but in my opinion they are worth it. Update: I purchased two more cables the last being in August of 2021, while the first two work remarkably well (PS5 and Apple TV), the last purchase I made something started to go wrong. I connected this last cable to my XBox One and right now the picture started to flicker and sometimes it would just go to black screen. I thought that my XBox One has finally kicked the bucket. When I started to pull the cable from the console the "SOURCE" side of the cable was extremely hot! I thought it was the XBOX! Turns out that the cable is beginning to fail, I replaced the fiber cable with another one and the problem was solved! I love the cable but maybe I'll purchase another cable from someone else. Don't get me wrong the cables are great but to fail in less than a year hmmmm?

### ⭐⭐⭐⭐⭐ Updated: Perfect customer service - you can't go wrong with Furui!
*by N***E on July 4, 2024*

This fiber-optic long-running HDMI cable has received more than a thousand very strong ratings from many happy customers, even while coming in at the lower end of the price range for this type of interconnect. It's features and capabilities and all the positive reviews are what led me to select this brand. However, there's yet another reason I will continue to seek Furui products in the future. After my product arrived I installed the cable in my family room to connect an Onkyo AV receiver to a ViewSonic HD projector at the other end of the room. It replaced a standard (non-fiber-optic) HDMI cable run of the same length. Neither of multiple standard HDMI interconnects of such length could deliver a stable signal to the projector. And that's precisely what these fiber-optic cables are for: very long runs. The new cable worked instantly and completely solved this problem. After a few months the cable failed. Because I had actually purchased two of these cables (the second for a different room) I connected up the second, which is presently working just fine. I assumed by then it was too late to exchange the broken cable. So I wrote my first product review to explain my experience. Within a business day after publishing my review, Furui practively contacted me about what happened, all on their own. With an apology, grace, and a brief conversation, the Furui representative offered me a redress so generous that it plainly distinguishes this company from others. In the end, the broken cable is being replaced and, furthermore, my time and trouble were also well recognized. You can buy a Mercedes-Benz and still get a lemon. It happens. Sometimes the consumer experience comes down to the company even more than the product. When that happens, you hope for fairness and understandng but often end up having an adversarial exhange with an overly stingy business representative. But that won't happen with Furui. Buy Furui and they'll take good care of you. By the way, the Furui cable delivers a beautiful picture :)
