I do this immediately when my TV’s image is too dark

Something I’ve learned recently is that more people complain about overly dark images than I realized. They can be a problem at any level, it seems. High-end TVs are less likely to suffer from this than budget models, but they’re not immune, and nothing’s going to wreck a movie, game, or show faster than being unable to distinguish objects or characters. More people might’ve liked the “Long Night” episode of Game of Thrones if they could’ve understood who was fighting who.
