I noticed the Green pixels on my set yesterday while watching a 4x3 program, and in the night time shots of deadliest jobs. you have to get pretty close to the set to see this, but when you back away i noticed that the image looked washed out. this was driving me nuts, but when I read about going to movie mode and then back to my cal-night mode, it completley went away. picture is much better. even if you dont see the green pixels from your couch, i think that if they are their, it is affecting the picture quality.
