I'm not even convinced that I'm seeing dither per say...at any rate, the noise is not like a totally different color or anything. You're way off the mark. Let's see him make noise disappear in a medium bright scene that is not just a single color. That's just a ridiculous comparison to draw into what I'm seeing. If I had complained about seeing individual sparklies of red, green and blue when I have a black screen up...then sure, your point is valid.
I do realize that what annoys me about the picture (and it's better than it was) is likely not objectionable to most people. So, don't be too concerned...It's just plasma tech, not a calibration issue.
What he was doing was an example
of how you can get noise from improper settings
. Man, you're so dense, why can you not see that? You don't see how that can be an issue on regular viewing content? If the middle of the gray scale is all out of whack but the blacks and whites are ok, then on regular content where much of the content falls in the mid spectrum, you'll get problems.
Plasma "noise" boils down to 3 things. Bad sharpness setting, creating artificial artifacts all over the place, bad calibration causing dither sparkles amongst other issues, and finally a noisy and bad video signal. Each problem can escalate the other. If there is signal noise, it gets "enhanced" by improper sharpness as each piece of signal noise will have sharpness artifacts around it and further worsened once you factor in bad calibration with dither sparkles all over the place. If dither is ok and not sparkling, then that means sharpness and noise could still be causing issues. If sharpness is off, and dither isn't sparkling, then that means the signal is noisy and problematic.
At that point, you might want to consider upgrading your video source or enabling such things as noise reduction filters and the like.
Again, if your set is properly calibrated (like EVERYONE has been telling you to do, lol) and you still get terrible noise, then it's the video source.
