I'm not sure where to ask this so I'll ask it here.
What exactly, technically, does black adjust and extended dynamic range do?
From my experimenting, they tend to work with local dimming to help mitigate blooming. But I really don't know what Sony's intention for these were. I sort of understand extended dynamic range based on what little information Sony gives, but I'm not sure what black adjust does.
I know I can just "leave it off" or "just do what you think looks good bro" but I feel like having a basic understanding of them and how they work together can help me determine if and when they should be used.
