I have a selection of 4K blu rays but I have been wondering for a while now why they are so grainy.
warehouse 4K BD -> Xbox one X -> LG 65" C8 OLED [very very min signal processing, settings on Xbox and TV following advice from HDTVtest]
I presume Hollywood adds grain to the movies?
Thanks for explaining to a confused person
(PS I know all of mine are upscaled 2K but it's not the resolution it's the annoying grain)
