I don't know. I spent a lot of time trying to change things during the NBA Finals game last night until I realized that what I was 'chasing' was in the broadcast. The broadcast would go from clear to 'noisy' continuously but I checked two other TVs in the house (one on basic cable and one on digital cable (HD)) and the signal was changing the same way. Switching to other stations afterwards and looking at things it seems to not be as bad as it was for that Mad Men episode. I did change my Scene Setting from the initial default (Auto?) to General. I don't know if the Auto setting was changing some things behind the scenes or not.
I haven't looked into the term but could the graininess I have seen be attributed to 'dirty screen effect'? Is that what it looks like? If so, is that a problem unit by unit (where replacement might be better) or is it symptomatic of all units made in this model?
No, if I understand what you're saying, the image itself was coming in grainy.
If the camera panned, did the grainy scene move with it? If so, then that's not DSE. If it looked like no matter where the camera moved that the effect was latched to a specific spot on the screen itself (like dirt would be), then that is the Dirty Screen Effect, and is can be glaring as hell.
There are moments when I also wonder where the graininess is coming from. I even saw it on a cartoon.
There are settings that seem to make it worse, or better, but my mind is spinning from trying to keep track of all this esoteric home grown settings-term-of-the-day Sony @#$% that I can't remember what did what.
That all said, compression effects can be confusingly subtle, and glaring as hell. I'm not talking about pixelation either. There were times when parts of the cartoon were totally clear, but a particular region that was a particular shade was in a kind of subtle snow or something. Like the color it was trying to hit was right inbetween two available colors and it hovered in between. Like dithering in a way. Still not sure.
