Apple tv 4k not accepting my 8k hdmi lead as being good enough for dolby vision on my sony kd55ag8 tv
Apple 4k tv tested my hdmi for suitability to switch to Dolby vision hrd and would not switch to that format so reverted back to standard format. So i purchased a high grade 8k hdr hdmi cable. Apple tv still wont accept the cable as being suitable. I have a Sony kd55AG8 OLED TV that has dolby vision capability on all hdmi inputs so not sure what the problem is with my apple tv 4k.
