That sample had had a screen replaced by an authorized tech, though, and I was unsure if it was representative of a normal sample. However, the next two I have done have also only managed in the 40's, and they had much worse black level measurements than the review set both with / without content and with / without black optimizer.
What I've observed might not be rising blacks as hours accumulate; it might be due more to a change in FW or manufacturing.
Wow, 52fL for the ZT60 and only in the 40fL range for the F8500! Things have changed quite a bit on these models as it has been widely reported that the ZT60 can only get to the mid 30fL range and the F8500 can go up to the id 60fL range. What happened to make this dramatic swap in peak luminance on these two competing TVs???? Also poor MLL on Samsung's F8500 has never been reported before.
What meter are you using and what window size are you measuring MLL and peak luminance in?
Sorry to bump this, but I wonder how this can be and thought it would be helpful for many of us to understand this highly debated differences between these two great plasma TVs. Everything I read on CNET and other reviewers says the opposite. How can you get 52fL on a ZT60 and only 40fL on the F8500?
