Which Chroma to use for my setup? I have AppleTV 4K and Sony X900E. AppleTV picked Chroma 4:2:0 with an option to select 4:2:2

Which one to use? I don’t know what those are supposed to do but I just want to take the most of my setup
To give a generalized answer, the larger the numbers, the better. However, some material may be optimized for 4:2:0.

Some Sony TVs are able to handle 4:4:4 (no subsampling) when enhanced mode is enabled, check if you can enable this for optimal signal.


Press the HOME button on the remote control
Select Settings
Select External inputs in the TV category
Select HDMI signal format and set to Enhanced format
