I see a lot of noise on my 60ST60, I see 12+ feet away too.. on some material its like snow.. I however have also seen this on lots of other things, it is not in the least bit distracting and more than that, the picture is sharp and very nice even with this.
I see a lot of noise on old black and white movies from the 30-60s and even more on the bluray version of band of brothers, I attribute it mostly to source processing and grain with some of it being the TV itself.
Its not that I dont see it, its that I have seen it and find the clarity and PQ to outweigh the negative. It does look like film grain to me and in some cases that adds to the experience. If I watch avatar I see almost NO noise (unless I stand right in front of the TV.
To make matters worse, I have all devices going through my Sony AVR and am using cheap 99c Amazon special HDMI cables, I have all the wires just bunched up behind the AVR or TV as well. I use to have the good cables, and properly routed. I never found a noticeable difference that would warrant the amount of time it took to do it "Right" I have pixel direct on, sharp set to 0 motion smoother and noise reduction off..
So, I have to agree with the others. it is there but is not objectionable to most of us, you are just more sensitive to it I think.
