    Cable would carry a 1080P signal, but it would not carry a 4k signal at any refresh rate. The exact same setup worked fine with a Monster cable at 4k and 120 Hz

    Perfect cable for in-wall use!

    I have always wanted to mount my TV to the wall to have it floating, but I hate seeing cables running down the wall. I had been looking for a good way to route some cables in the wall that would be future-proof so I wouldn’t have to do it again for a very long time! Along came the Rocketfish cable. Right out of the box you can tell this is a very premium cable. It is nice and thick and the ends are very high quality. I don’t have an 8K TV (yet) but I want to be ready for whenever I do get one. I do have devices that take advantage of Dolby Atmos, and 4K video as well as having a PS5 and things like which really benefit from a high end cable that can handle high data transfer rates. I got a couple of these and ran them inside my wall from my TV down to my sound bar (yes they are rated for in wall use). Since they are kind of rigid, they were very easy to fish through the wall. I hooked them up to my sound bar and Apple TV and they worked perfectly. Dolby Atmos was firing on all cylinders and the 4K video looked very crisp and clear. I even hooked up my PS5 to one of them and had absolutely no problems running very demanding games. I would highly recommend these to anyone wanting some premium HDMI cables for your home theater. Especially if you want to run them in your wall. They cant be beat!

    Makes a huge difference

    So, I was skeptical if this would help out and make a difference or not. I got used to using a cheap HDMI cable hooked up from Xbox to TV and thought it looked nice. But getting this to try and definitely made the pictures a lot clearer. I also like that it is 15' so I can run it to my laptop if I want. I like that its braided as well. My oldest son also was impressed at how much difference it made. He keeps taking it to use with his setup for his ps5. I could not see too much of a difference though it not on a 4k tv or monitor. I have a regular HD monitor (1920x1080) in my room that I use and did not see a difference with that which I was not really expecting that. But for my TV that only has 4k it definitely made a difference. Sadly, I do not have an 8k monitor or TV to try this on. But gaming feels a lot better now in 4k. This allows you to be able to play at 120hz when allowed. Like I said, I feel it is worth picking up and recommend it if you do have a 4k TV/monitor. If not, I did not see a difference. The length is plenty long to reach.

    Immediate Improvement

    I have an 8K TV but didn't realize i should have upgraded my HDMI awhile ago. This is absolutely made for inside the wall connection if needed. It's a strong and well put together cable. Once I connected this to my Samsung TV and soundbar, I saw and heard an immediate improvement. Picture has never looked better. Not only did it improve my picture, but so did my audio especially with my surround sound speakers. Some of the highlights include 48Gbps which creates bigger bandwith. It creates and maintains excellent refresh rates for both 120 and 60hz. It is also rated as HDMI Ultra High Speed and it certainly shows. It also allows for Dynamic HDR. It supports Dolby True Sound and Dolby Atmos. Those who are familiar with Dolby Atmos, you will absolutely appreciate the updated sound. This particular cable provides 15 feet of length. Rocketfish has been a reliable brand, and this cable is no different. They seem to always keep up with the latest trends most importantly technology-wise. I would definitely recommend getting one if available.

    Getting a truly certified cable really matters!

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I have a Xbox series X hooked to a Samsung Q900TS (2020) 8k TV. Using a supposed 8k HDMI 2.1 compatible cable the Xbox said my setup did not support 4k 120 fps. I got a CERTIFIED Ultra High Speed HDMI cable and low and behold, 4k 120fps worked just fine as did ALL of the other features of HDMI 2.1. At this point in time I know of only two companies making true CERTIFIED cables for HDMI 2.1 at 8k. This is one of them and Planetwave is the other. Get one or the other. Don't get the pretend ones that don't work, even if it is from a so-called reputable manufacturer. Look for the HDMI.org scannable label on the package and go to HDMI.org to see how to tell a certified cable from a make-believe one. At the speeds and features we are now running with these new 8k setups it makes HUGE difference. The HDMI cable world is one of the biggest consumer product cesspools out there right now so be careful!

    Like another review mentions, this cable will not allow you to display 120hz upscaled to 4k on Xbox Series S. It only allows 120hz at a forced 1080p with NO HDR which is a big bummer. The cable the comes with the system works just fine however. Will be returning this one.

      Hello,
      Thanks for your feedback.

      Checked with the certified 3rd party that the Xbox series S supports 2K 120Hz but not 4K 120Hz.
      Also, checked Microsoft's official website, it shows Xbox series S doesn’t support 4K 120Hz. BBY-ExBrand_RocketFish
