Had with me in the house to 6410 about 10 days. The illumination errors at the 4 panel edges, clearly visible in bright background, plus gray shades have me at div. Try setting eventually forced to give up. In fast football scenes still was added a gray veil. The test reports the illumination problems were identified and the gößte part of owners will notice this deficiency at all. Samsung says physically due to the arrangement of the LEDs on the panel edge, this is normal. Have previously nine years had a 46 inch LCD, this was due to pipes as a background image ecellentes. That there is another way proves Sony, in my case the 55W805B which provides a flawless, error-free image with excellent picture quality. The very good reviews are a mystery to me personally, because in a large electronics market, at least in all the Samsung 6 Series had described more or less strong illumination mistakes as me.
