I bought a black/grey 8K Audiano HDMI 2.1 10ft cable. For over a year I assumed my 4K display was flickering due to AMD drivers for my GPU. Tried this cable before replacing other hardware. The black screen flickering and refreshing stopped completely. I don't have 2.1 8K60 compatibility test hardware. But all I know is that my TV flickered with an HDMI 2.0b cable. There is no flickering. The quality of the material is also excellent.
