Have the TV now 3 months and it is not a day that I do not regret buying! About 50% of my panels are affected by Clouding. Yes, I know this can be countered with the settings a bit and yes I have converted all the proposals of support, without improvement. A good buddy (Head of TV in MMarkt) confirmed to me that this exceeds the tolerance values to wide. After then the service did not know what I was to repair or replacement, this changed the tactics and only answered with yet "it has been designed for" and "do not change" to "it's just so" ... repair or exchange has been completely rejected. Well thank you Samsung, since one is yet glad to have invested his money with you. Never again!
