Thanks for clarifying this koffas. I was actually going to ask you about this specific behaviour of floating blacks but you have read my mind
You see, on my previous Panasonic, a 54V20, I found the floating blacks to be intolerable due to the specific way they had implemented it (i.e scene change...wait...then black floats up/down...so annoying!). Whereas the floating blacks on my other Panasonic, a 42PZ800, are instantaneous with APL, and funnily enough I find it completely tolerable. Although on that set, the MLL itself doesn't change, just the low end gamma brightens/darkens depending on APL. But as mentioned, it's instantaneous, so on a scene change you don't even get time to see it happening.
For the Samsung though, I would have to see just how much the black level floats, and where exactly the threshold is. If the threshold is set high enough, and it's instantaneous enough, it *could* be ok.
Question: is it only the idling pixels which change in brightness, or is it the entire frame that gets brighter/darker?
