Ok, this is driving me insane. I just got this new tv and the picture is absolutely disturbing. Is there a calibration setting somewhere for this model? Not sure whats going on as I had a un55c6400 before and the picture was gorgeous with some simple calibs. I tried a blu-ray and it looked just good but running Comcast hd is absolute garbage imho compared to before so I don't know whether its the tv or the Comcast hd problem. Any ideas or help?
