This thread doesn't seem to be too active any longer, but I'll give it a shot here since it is the most appropriate thread.
I recently tried to adjust the settings on my S2 using the WOW disc, (i'm in Cinema mode, Warm, and used DNices offset adjustments for the S2), and even at 100% contrast I still can't get the whiter-than-white patterns (+1, +3, etc.), and even the ideal white pattern, to blend into the background. I need to go higher than 100% contrast to get there, and I can make it work by raising the brightness (which is in the high 50s), but doing that messes up the black levels. Is this a consequence of panel aging? What can I do about this, aside from having custom calibration (i'd rather wait for that until i get a new plasma in 1-2 years)?
