I have already adjusted those settings. The blacks get darker but the cloudiness remains. I messed with every single setting and the one that worked the best oddly enough was turning on True Cinema. Unfortunately it over-darkens the entire picture and the HDR effect is almost completely nullified (the cloudiness is still there but almost impossible to see unless the room is pitch black). When you hit stop on the movie, you can instantly see the areas of the TV that were gray and cloudy turn jet black with zero cloudiness. I'll try a full TV reset later tonight.OK, I viewed the closing credits for a movie, white characters crawling across a totally black background. I toggled the Auto Dimming through its settings and could not see any difference.
Here is something for you to try when you have a spare minute. When you are seeing washed-out blacks in HDR mode, bring up the Picture Settings menu and adjust the Black Level setting up or down. To me, Black Level has the most impact on how black a black screen is. See if it makes a difference.
