I have read as many posts as I can about this and tried every calibration setting imaginable for my UN60ES6100, while my problem is similar to others, mine is a bit more specific. I'm asking about the "dimming" – most notably while gaming on Xbox 360 as well as watching movies with dark scenes.
My problem is that, for example, while playing Halo 4 or Borderlands 2, when I move into a dark area, shadow or just a dark room, the whole screen gets dark, and not just the scene but other elements that normally would not dim in-game like the HUD display, Heath bar, cross-hairs, menu etc...
Everything is fine when I move out of the dark area, brightness and colors are vivid and damn near perfect, but as soon as I get to a dark area i get what would be close to the "Black Crush", the difference is, EVERYTHING gets dark. Menus, maps etc..
I have tried all the usual suspects: Eco Sensor OFF, Motion Off, Game Mode on/off and so on, it even happens when in MOVIE mode. The only thing that works is when I turn HDMI Black off, but then the colors get washed and everything is grey.
I have read about going into the service menu to turn off dimming but I just got this for Christmas and don't want to void the warranty. Is there any solution to this specific problem? Thanks.
