This is my first Samsung so not sure what setting I am missing. I had bought a 55"LG 4600 and worked on the adjustments for a week and had a perfect picture. Lines were crisp detail was excellent. But clouding and flash-lighting was horrible. Tried a Vizio, too many thing wrong with that. Thought I would try the Samsung because I really like the features and the look. It.s only 1" thick with hardly any frame. I just can't get the picture as good as I had the LG. The specs looked a lot better then the LG 240Hz Vs.120Hz Contrast ratio a lot higher. I am hooked up to HD (cable) and HD DIsh Network (HDMI) Any help would be appreciated before I send it back.
