Depending on various settings and conditions, the TV may have a cloudy appearance in areas where the screen is displaying very dark colors, or black. Black is one of the hardest colors to produce, and various things can cause this type of issue, such as the preferred color settings, the environment where the TV is located, or the content displaying on the screen. A bit of trial and error may be necessary to find the setting which displays the picture as close to the preferred settings as possible while also reducing or eliminating the clouding.
