    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.

    Great Value

    I needed a longer cable to connect. I required the cable to be capable of doing 4K resolution at 120 frames per second, and this option looked to be the best value in the store. I've had no issues with performance.

    No cap. It’s a really good quality cable!

    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
