Far to often there are sellers that claim their product is one than and it turns out to be something completely other than what your paying for. That's not the case here. If you have a 8k video source @60Hz or 4k @120HZ will will get the benefit this cable provides. As soon as I switched from my old so-called "4k 120Hz Cable" to this one....the difference was instant and dramatic. (And yes it 100% works with PS4, PS5, Xbox Series X and so on)5/5 stars. Highly recommended.

As others have said, it works @ 4K 120Hz 12-bit colour. Even with a 10 ft cable its doing great.

This cable is NOT capable of 4k120hz on PC. The option is there to set the correct settings but as soon as you attempt to adjust the refresh rate of your 4k display above 60hz, the resolution will drop down to 1080p WHILE STILL TELLING YOU ITS SET TO 4K! This is the fault of the cable. My old ps4 hdmi cable is able to give me the same quality as this cable. Don't waste your time with this and don't be fooled by the other scam reviewers like i was

The picture on Amazon show that it's supposed to be a certified HDMI cable... It is not.Unless you have proper equipment to test these yourself then don't bother ordering them.If you don't care about the speed then buy something cheaper.I finally went with primecables you get a real certified cable. (you can verify it with an app)In the end this is a scam

Unlike some other sellers on Amazon, this is actually an 48Gbps HDMI 2.1 Cable. At 20$, it sounds expensive but this is competitively priced on Amazon for a 10ft cable of this type. I have been using to connect my laptop to a 144hz monitor and it works perfectly! Also, it is well build, simply designed and it wasn't too stiff out of the box. Highly recommended!
