    Certified Ultra High Speed HDMI cable

    This is one of the very few certified Ultra High Speed HDMI cables for use for HDMI 2.1, 8k, 4k at 120fps. Get this, not some fly by night (or even some "reputable" manufacturers imitation non-certified cables. I have added a photo of the box this came in as well as a photo of what you should expect when you scan the QR code on a truly certified cable (which to be truly certified must be o the box thereby showing it was actually tested. Also, the scan will confirm that the HDMI.org or it's representative have actually tested the cable. Of course the crooked cable makers can fake the label too but they can't fake the result of the scan. The HDMI cable market is one of the biggest cesspools in consumer electronics right now so be careful buying cables. Kudos to HDMI.org for at least getting a start on drawing this cesspool. Now for the rest of the story: I have an Xbox Series X feeding a Samsung Q900TS 8k tv. With one of the fake cables that claimed to be HDMI 2.1 compatible I could not get the Xbox to use 4k 120 fps. All I did was get a real, certified cable and the 4k 120 fps worked just fine. Don't buy non-certified cables, by doing so you are just encouraging the crooks to keep on making false and mis-leading claims about their cables.

    Built solid, heavy duty, shielded cables, perfect for in wall use. Bought (2)15’ footers to run from our A/V closet to behind the TV in the framing, before drywall was installed on our new home. The ends are the perfect size to fit through a small drilled hole, and the cables and connector ends are extremely robust.

    I’ve used this HDMI cable for about a year now and i’d HIGHLY recommend! I’ve had no issues and if you’re looking to support a higher quality monitor with high refresh rate then this is the HDMI cable for you! Quite often I find that my HDMI cables deteriorate or just simply break but this cable has lasted me a full year with no issues and i’ve had it plugged in at a weird angle. Other than that I would definitely recommend this product to someone who is looking to support 1440p gaming with high refresh rate.

    Originally, I bought these cables for my 4K Media Player but got the 2ft one and it wasn’t long enough. Instead used it for my Gaming Console and Wow! I have the Vizio 4K M series and it has a “pro gaming engine” feature in it. I never saw that feature until I installed this cable for Gaming Console. It really makes a HUGE boost difference in quality. I notice all my old cables are 18gbps. This one runs 48gbps and if you want true 4K HDR experience, buy these cables. I’ve literally ordered 2 more cables, one for my 4K Media player and 4K Apple TV. Can’t go wrong with them. Trust me

    This is my second purchase of this product. I have another cable such as this at my house for another machine. I really love these cables. The price is worth it, and the feel of the cable is top quality. I wish this brand made XLR cables this thick. I'm a visually impaired user of this product and plugging it into the ports was easy. For those though who get this cable for the first time be aware there is a thing which covers and protects the port. Take that off and throw it away. I could not get the first plug to fit for the life of me and almost returned it when I pulled and the protective cover for the port came off. I am now a happy camper every time. I highly recommend this cable.

    Urgently needed high performance, high quality HDMI cables for a video display themed trade show booth for our company. Potential customers of our products would quickly pick up on poor quality. We couldn't have cables causing problem with our video feed. I relayed this info to the sales associate at the time and he recommended these cables. They worked great and are of robust quality that will be used at future trade shows.
