Thanks for taking the time. I truly appreciate it.
Just to make sure that there is no misunderstanding, let me restate in a different form what you said.
With your D7000 and a 1080i source, these settings cause no obvious brightness fluctuations:
#2: cell = 15, cont = 80, gamma = +1
#2a: cell = 20, cont = 70, gamma = +1
And this setting with a 1080i source causes very obvious brightness fluctuations:
#3: cell = 10, cont = 94, gamma = 0
You can see where I am going with this. Right now, all or a combination of all of the three variables could be the cause of the fluctuations -- again, at least for your TV. At this point, I am reluctant to ask for a change in gamma from +1 to 0 because that will require a significant change in the brightness setting to maintain a decent picture. And that, in turn, will only add another variable and make the problem more complex.
So I guess that the only reasonable request that I can ask of you is to create a #2b condition with cell = 10, cont = 94, and gamma = +1. (Of course, this might require a very small adjustment of your brightness setting.) You decide if you want to continue playing.
