I have been using this televison for about 2 weeks now. I have been using natural color settings and I think this is the best setting for me. I am watching in a dark room and there is clouding in the middle of the screen. If I adjust the movie settings and set the dark tone, I almost get close to natural color settings and I don't notice that clouding in the middle of my screen(it is still there but not noticable). No matter what I try, natural settings always find the best colors for every scene it certainly beats my calibration and the colors seem better.
Natural settings does not allow me to change advance settings, the menu doesn't allow me to get in there. Is there a way to set black tone for natural color settings so that I don't see any clouding.
