    all of the 2.1 cables were out of stock so I had to spend an absorbent amount of money for this reinforced cable, and it proceeds to break in a couple of months. Never put it in a wall just ran it from my computer to my monitor. Even though I know most of you wouldn't waste your money on this overpriced cable make this a second reason not to.

    Strong and durable HDMI cable

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

    When you're purchasing an HDMI cable (or any sort of cable, really), the first thing you want to consider is how you plan to use it. If you want a cable to put in your laptop bag, you might consider things like weight and abiity to coil tightly. On the other hand, if you want a cable to run through your wall as part of a permanent install, you want something rather different - you want something thick and durable regardless of weight, something that will LAST in a permanent installation. You also want something that has a bit more "stiffness" to it, to make it easier to feed through the wall conduit or air gap between studs. And you want something with a good length to ensure you have a good amount of cable left on both sides to make whatever connections you want. In short, you want something that you can run the first time and leave it for a long time - including being at least somewhat future proof in capabilities. This particular Rocketfish cable checks ALL those boxes for an in-wall installation - it's a HEAVY duty cable clearly meant for a long-term installation and rated for in wall duty (which is important). It certainly can flex to accomodate being run through a wall but also can hold up to being fed through that wall. And it's the highest spec of HDMI currently available so while nothing in technology is truly future-proof, this cable does give you some good headroom to grow in the future (it supports bandwidth to 48Gbps which is sufficient for high framerate 4K or 60Hz 8K with other goodies like HDR turned on so you should get a number of years of use out of it). Beyond that, it's a generous length at 15ft (though of course measure to make sure that it's long enough for your purposes with some left over at both ends if you do plan an in-wall installation). And of course it works as advertised - run the cable, plug in both ends and it works just like it should. So there you have it - a top notch heavy duty in-wall HDMI cable meant for the long haul. If that sounds good to you, give it a try today!

    I bought this when I got my OLED TV so that I could it with my PS5. It worked for about a day and then I started getting lines in my TV while playing my PS5. I purchased an Anker HDMI cable from amazon that has worked flawlessly and haven't had the issue since. This cable went in the trash.

    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

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

    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
