A:Answer I don't believe you will be able to get rid of that. The clouding is a common issue with edge lit back lighting on LED TVs and the severness varies from panel to panel. A TV with full array backlighting won't have that, but also causes the TV to be a little thicker. I believe Sonys 940 model is full array, but it is also way more expensive.
If you have your TV in a darker room, you might be able to minimize the clouding effect by keeping the brightness settings low.
