Not sure how active this part of the board is, but giving it a go anyway. I got myself a Hisense 4K TV and overall I really like it, but I am struggling with this so-called 'black crush' where dark/black areas of the screen are often block dark and have little to no definition of the detail in them. What is the best way to configure a screen to bring the full clarity out? My screen is Hisense H55N55000UK - which might not be 100% useful for you guys to relate to... this board is Dutch isn't it? American? Anyway, advice again welcome! Fanx!
