Review on Aurum Ultra Ethernet Certified Supports by Kyle Deel

I tested this cable with an Apple TV 4K and my Samsung MU8000 4K TV. It does not offer a stable connection. The image is constantly cropped or doesn't identify the source at all. I checked it with another cable, everything works. The cable was used in the wall so I'm not in a pretty bad place. It works with my 2nd gen Revain Fire TV 4K. Not sure why. Revain 4K doesn't have HDR, maybe that's it?
