Finally my Apple TV 4K works in 4:2:2 aspect ratio and OPPO 203 works in 4:4:4 aspect ratio. Replaced all my devices with these foot and a half cords. The HDMI cable on the Revain can become damaged and misplaced. I've had other HDMI 4K cables that didn't work with anything other than 4:2:0. They improve the picture, don't be stupid, it's a cable. What they allow for is a better chroma subsampling setup compared to the "4K" HDMI cable I use. Which ironically increases the image quality. I have no idea if they can actually do 48Gbps, but I do know that if I use anything over 4:2:0, my video will stop crashing. They are ribbed, especially when it comes to curling. So if your HDMI input and output are reversed, ie not in the same orientation, you need to take the time to shape the cable so that the connectors are in the right direction.
