I dont usually display a certain image to test, it is just something I notice at times when there is a darker scene on the TV. I often notice the black levels when I'm playing music off my receiver as the screen is almost completely black with a bit of writing on it for the artist and track name. I also notice it often during the end credits of movies, with both Netlfix and DLNA.
I believe I'm still using D-Nice's settings that I originally used back in 2012, but I would have to verify that. I'll try to remember to take some pictures tonight and also check my settings.
When in a completely dark room and there is nothing on the screen, like the picture in my previous post, what does your GT50 look like? Is it basically completely black or does it look more gray like the right tv in that picture?
