Does anyone know how to raise the chrominance of the Apple New Apple TV 4K from 4.2.2 to 4.4.4?
Yesterday, June 4, 2021, I bought a new Apple TV 4K device at the Apple Store
My disappointment has come when I have verified that with 4K HDR at 60 Hz the chrominance is 4.2.0 and at most 4.2.2.
I have tried the different HDMI 2.1 cables from Belkin (Ultra High Speed recommended by Apple) and also another one with a higher data rate the KabelDirek Ultra High Speed (4K at 120 Hz, 8K at 60Hz and 10K at 30Hz at 48 Gbit / s and UHD II) (Maximum functionality: HDMI 2.1 standard supports 48Gbit / s UHD-II resolutions, such as 7680 × 4320 (8K) or 10240 × 4320 (10K), 3D video, 48-bit colors and functions such as Dynamic HDR / HDR10 + , VRR, ALLM, HFR and eARC (Dolby Atmos / DTS: X) but none of them achieve the 4.4.4 chrominance.
Does anyone know how to get this Chrominance upgrade to 4.4.4?
Thanks
