Review on 🔌 FURUI Fiber Optic HDMI Cable 100ft - 4K 60Hz, HDMI 2.0b, HDR10, ARC, HDCP2.2, 3D, 18Gbps, Subsampling 4:4:4/4:2:2/4:2:0 - Slim & Flexible HDMI Fiber Optic Cable by Nathan Jones

HDMI cable that really delivers true 4K HDR my wall mounted Vizio P75 TV across the room for which a 25 inch HDMI 2.0 cable was required. Two 4K HDR sources, an Oppo UDP-203 Ultra HD Blu-ray player and a Revain Fire 4K TV Stick, connect to Onkyo's HDMI inputs. Before I moved the receiver to the other side of the room, everything worked with a 10" high-speed HDMI 2.0, HDCP2.2, 18Gbps cable. If you're using relatively short cables, 15 feet or less, the length of the cable usually doesn't cause any noticeable signal degradation, and some even say you can increase it to 20 feet. I've tried several 25-foot and 30-foot cables, including Monoprice's Cabernet Ultra Series Active High Speed HDMI Cable, KabelDirekt High Speed HDMI Cable, and this cable, and none of them could fully support full 4K HDR with Dolby Vision. I returned this cable, posted a review, and the company immediately contacted me to find out a little more about my cable issues. After a short exchange of e-mails, a replacement cable was sent to me and I have to say that it has been working great for a few weeks now, the picture is great. Watching The Space in 4K UHD on Revain Prime looks great and Gladiator in 4K HDR/Dolby Vision on Blu-ray looks spectacular! The first FURI cable had "handshake" issues (which I'll discuss below) with my receiver that wouldn't allow it to transmit video when I turned on Full UHD on my TV while not switching cables . The new cable works as advertised, transmitting 4K @ 60Hz with full HDR including Dolby Vision from the Revain 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 eliminating thick video cables instead of thin fiber optic cables, this cable is very easy to manage and particularly easy to hide in tight ducts. Be careful not to pull/stretch or bend it too much as you could damage the very fine fibrous elements within. FOR EVERYONE WHO WANT TO KNOW MORE ABOUT HDMI, 4K AND HDR CABLES READ MORE... When I first bought an HDMI cable I really didn't know what all the numbers and specs mean and why they matter . Here's a brief introduction to help you understand what it all means. 4K refers to how many pixels are on the screen, while HDR (high dynamic range) is the range from lightness to darkness that those pixels can cover with either brighter or dimmer lights. black areas or a combination thereof. UHD or "Ultra High Definition Television" is an industry specification that combines the two (plus some additional features) into one easily recognizable term. Consumer video is stored, transmitted, and processed in a color space called Y'CbCr. The three components are: Y' = lightness or brightness of a pixel, Cb = blue difference and Cr = red difference. Three main types of color subsampling are currently used. These are 4:4:4, 4:2:2 and 4:2:0. If 4:4:4 is a full bandwidth signal, 4:2:2 occupies 2/3 of the space and 4:2:0 1/2 of the area. Blu-ray and UHD Blu-ray store videos in 4:2:0 format on the disc. When this disc is played by the player, it is upconverted to 4:2:2 format, which can be connected via an HDMI cable transmitted to the display, which upsamples the signal to 4:4:4 format and converts it to RGB. Because the display does most of the upconversion (4:2:2 to 4:4:4 to RGB), it reduces HDMI bandwidth requirements. If there's a home theater receiver in between, it'll just let the signal through, although some of them can handle the signal if your player or TV can't do the job. There are different types of HDR formats: HDR10, HDR10+ (Samsung's answer to Dolby Vision), Dolby Vision and HLG. All "HDR" devices support HDR10, while support for other formats varies by manufacturer. Currently, almost all companies also support Dolby Vision and HLG, only Samsung refuses. Since their Blu-ray players only supported HDR10, sales have been mediocre, and Samsung says it won't release any new 1080p or 4K Blu-ray players for the US market from February 2019. its technical limitations as HDR10. Dolby Vision uses frame-by-frame metadata (metadata is data sent with the picture portion of an HDR signal that gives the monitor additional instructions on how to display video by adjusting the brightness levels and color range) to to control power and the amount of data sent over cable. Dolby Vision content is processed at 12-bit color depth, compared to the 10-bit color depth of HDR10 (hence the name HDR10). UHD Blu Ray is also 10-bit when it hits the display, and most new consumer TV displays use 10-bit panels. the same page that requires the exchange of metadata between them. HDMI handshaking is a process that takes place between the source and the display that does exactly that, when it works, your video and audio signals are properly transmitted over the HDMI cable. Many cable "dropouts" are due to handshaking errors that result in audio or video signal dropouts. Inside each HDMI cable is a pair of wires for the DDC display data channel (pins 15 and 16). The DDC contains two types of data, HDCP (Copyright Data) and EDID, Extended Display Identification Data, in a metadata format for display devices such as televisions to describe their capabilities towards video sources such as home theater receivers, streaming devices, Blu-ray. Disc players and even game consoles. This allows video sources to send a video signal supported by the display. If the data going through these two wires is corrupted or below the specified voltage (5 volts DC +/- 0.3), you may not get a decent picture, the correct resolution, or no picture at all. Therefore, it is important that every connection within the cables connecting your devices works properly. Voltage drop can occur with longer standard cables and if the voltage drops below 4.7 VDC handshaking problems can occur which can degrade the audio and/or video signal and can affect the high speed Y'CbCr video signals. through her. By replacing thick copper wires with thin fiber optic cables, signal loss problems have been greatly reduced. We hope this additional information not only helps you understand HDMI standards, but also gives you a better idea of how to set up different devices. If anyone has any questions, please ask.Art
