Simplest way (equipment/software) to determine cd/m2 [nits] on a TV?
I'm looking for a simple, accurate way to determine brightness of a TV in SDR. IE, if I want to set it to 120 cd/m2 [nits], or if I want to set 200, something that will let me determine what that brightness [backlight] is.
This is on a Sony TV. It does have AutoCAL, which I'm considering as I know it would do this and more. But I'm also considering just getting something so I can do brightness instead.
Kind of new to all of this, so appreciate the help! Thanks!
