Pros & Cons


Seems to be a nice HDMI cable. Quality looks nice. I can't speak to the 120hz yet. When I can, I'll update for that. I can say that these really aren't any better, picture wise, then some 5 plus year old cables I have. swapping between different ones, made no noticeable difference in picture quality. Unless there is a specific need like 8k or 120hz, you may want to consider shopping for less costly alternatives.

Works fine. I had to get a new TV but I didn't have 4K HDMI cables. You know the salesman will try to sell you things you don't need and she had given me a $40 4K HDMI cable. When I connected the cable the quality of the resolution was amazing! Well worth the price and worth waiting.

Must for gamers and viewing quality. HDMI 2.1 8k allows PS5 to push 120 hz. Pic quality unreal. If you don’t use 2.1 then PS5 will only push 60 hz. Hooked another one up from cable box to my LG OLED and BAM so good!

No complaints! Looks sturdy. Works well. Received quickly. No complaints whatsoever. Thanks!

Works fine, just not that sturdy. Well packaged and it looks well made. Plugged into my eARC HDMI on my LG TV and Denon Receiver. Worked well for 30 minutes as I set up both new components. Unfortunately, during this setup, i had to go behind the TV and adjust some plugs and hookups. My 3.3' HDMI cable was too short for the pivoting TV mount and I pulled the male plug off the end of the wires. My fault for ordering too short a cable, but I will pay extra for better build quality and have ordered a 4' cord from another manufactuerer that looks more robust.

Good quality. I ordered 3 of these to redo my TV stereo and lighting set up. All 3 worked perfectly and my sound and video is flawless.


Artifacting. Don't know if it's my 3080 or this cable but Sometimes I get green lines and my video cuts in and out. I believe its the cable because I was using old HDMI cables on my LG C2 and had the same issue only much worse.

Worked for a while, and then it didn't. I was really excited when I plugged this up, ran it for a while and everything was perfect. I'm running a 42inch LG C2, connected to my PC with a 3090 @ 120Hz. I have another cable that works perfectly, but it's really stiff and cable management is really tough using it. So, I thought I'd find something that's easier to manage. After a week or so, I started getting flickering, and bands would appear across the screen. Things would blink, things would just act goofy and look weird for a moment and then go back to normal...just a bunch of graphical anomalies. Not work it, if you're looking for 4k @ 120Hz IMO.

Not good. Cable work for 15days only after that it was loosing signs like crazy... bought and nother on from a different brand, problem is good now. And its too short

Almost does what I wanted. I bought this to split an HDMI signal and watch two separate TVs at the same time . But it does not send enough signal for both TVs . Only one TV at a time . Oh well .

Nothing much. Didn't see or hear any differences from a regular grade cable. Not expensive but certified? For what ? Certified to work regularly.

Loses Signal! Don’t buy! My monitor will shut off or it prompts a message saying lost signal and it’s a black screen with the message. I bought the longer cord but I’m not going to take my chances with the shorter cable. I’m just going to buy a totally different product bc this one is worthless.
