Rocketfish™ - 4' 8K Ultra High Speed HDMI® Certified Cable - Black

Finally a certified cable with HDMI scannable label. Great quality and in wall rated. I used it for installation of my tv on wall.

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.

Good quality cable that surpassed the included “HDMI 2.1” cable included with Xbox Series X. I picked this up as an impulse buy when walking to the register to pick up my Series X on launch day. When I opened the Xbox I realized they had included an “HDMI 2.1” cable with the console, so I initially thought “great, I can return the extra one” and save some cash. Turns out that I’m glad I bought it! I have an LG C9 OLED that supports advanced features like 4K @120hz and VRR. When I tried using the included HDMI, I kept getting loss of signal @120hz. After a while messing with settings, I decided to try out the Rocketfish HDMI 2.1 cable. Instantly, no issues with any advanced features. Still running strong at 4K 120hz and not a single issue 2+ months later. I’m assuming that the cable included with my Xbox was faulty, but super glad I picked this up to save myself a further headache troubleshooting things.

The cord SONY includes with the PS5 is like 1 foot long. Seriously sony?!?!? SO I needed a HDMI 2.1 cable capable of high speed data transmission so I can attempt to reach 144hz at 4k on my Samsung 4k TV (which has a HDMI connection to support this refresh rate). Everywhere I read said to use the cable included with the system because of the HDMI 2.1 etc... Doing a little research I ended up going with this cable. Certified by HDMI .com or whatever. I can say this is the cable you want, if you need something longer like I did. Cable works great, Once I enabled "game mode" on my TV I could see the difference and Demon Souls plays at 60 fps+ (not that the included cable couldn't do this, I'm saying that this cable is compatible).

Bought these cables to hook up to my Sony X900H TV, PS5, and even my 4K player. They work great. I've had no issues. These are authentic, certified cables so you can rest assured they've been thoroughly tested and meet HDMI.org standards. I recommend these mainly for gamers who have a newer TV capable of 4K-8K resolution with a refresh rate up to 120hz and a PlayStation 5 - that's who can benefit from these cables the most at the time of this review. These Rocketfish 8K Ultra High Speed cables are mainly for next-gen TV's and video game consoles released around or beyond 2021. Also, watch your wallet. These cables are a bit pricey so if you have an older TV, regular Blu-ray player, or older video game consoles released prior to 2019-2020, you're better off getting cheaper cables for that stuff since there would be little to no difference in video or audio quality. Besides that, these can be a good, long term investment. I highly recommend as long as you have, or plan on getting, the right gear.

This thing is really nice. First off the box design is what caught my attention. It gets 4K up to 120hz which is perfect. It also gets up to 48GBPS, I wasn’t sure that was a lot until I googled it and it turns out it’s A WHOLE LOT. it also supports eARC which is cool if you have a sound system or sound bar. I’m currently using mine on my Xbox. They’re also very pretty and shiny haha. I already purchased 2.

Great cable, excellent quality, but definitely too expensive for what it is. But this being “bleeding edge tech,” and one of very few REAL HDMI.org Certified 48Gb/s HDMI 2.1 cables in existence currently, it is what it is. I can confirm this cable works with RTX 3080 and LG E9 (and C9) OLED TV (f/w 5.00.03) for 4K 120Hz Full RGB 4:4:4 w/ HDR & Gsync!

The HDMI cord has made gaming with the new Xbox series X even smoother. I also use this HDMI cord on my Xbox one S to get the most out of it. The only thing that is not ideal is the cord is pretty stiff so it's hard to fit it behind TVs that have ports to hide cords.
