Look at the first post. There are a couple of clips there that are supposed to show it.
Which brings me to something I was going to post about ... Do They?
I have a 51D8000 and I have not been aware of these brightness pops during regular viewing. Not sure if it's because I'm looking at the content instead of the black bars, if some of these sets have more or less of it, or what. I am very picky, in general.
The test clip with Bogart has a lot of brightness changes, but I see these with my LCD computer screen and my Samsung LCD as well. It didn't look any different on my D8000, at least to my eyes. I don't think that is a good test.
The other clip which is supposed to have a lot of pops has only some very subtle changes if I look at the letterbox instead of the actual content. And I only can see this if I hold something up to shield the main content. I didn't see anything in that clip that I would notice if I was just watching the content.
Something I've asked elsewhere but not had any confirmation of is whether the test on the AVS Rec709 disc represents FBr. In the Miscl. group of test patterns it is the last one, A5, and is called Dynamic Brightness. It shows a small grayscale which changes as the overall screen changes through several levels of gray. I think this is at the very least a demonstration of the normal ABL that plasmas require, but it seems that it would have to include whatever FBr is beyond what plasmas do with ABL. On my Samsung LCD these gray bars remain constant ... of course.
How do we know when normal ABL behavior becomes the objectionable "FBr" .. or how can we tell the difference?
