Does anyone have a well used Samsung plasma from last year that they had initial black level readings from, that they can re-test? I guess my question is, if Panasonic is telling the truth and all plasmas have a black level increase, the 7000 series won't stay at the 0.027 that it started out. It might not be accurate to say that a 7000 series will have the same black levels in a year as a G25.
I have no idea if Panasonic is lying about this, hence why I ask if anyone has a well used plasma from last year with initial measurements that can be retested. Or heck, if we know that last years model had x level generally, we could test anyone's that has been well used and compare its values to those of the average initial values. Who knows, maybe the black levels have actually lowered!
CNET will be monitoring this and the evidence is anecdotal so far, but I have yet to hear of a report of diminishing black levels on other brands of TVs. The Kuros have been out there for a long time and if this was an issue you can bet that the community of Pioneer owners will have been screaming. Maybe people have been too worried about Sammy's buzzing to notice a change in black level?
While it may be true that the pixels will take more voltage over time to respond, I think that Samsung and others just start there address voltage levels higher to begin with. This results in a higher initial black level, but less (or no) change over time.
Like I said, I would love to have lower black levels, but I am looking at the whole package. Black is important, but I think it is a bit overemphasized. Most people cannot actually see the difference between 1000:1 and 3000:1 contrast ratio (which is about the difference between the c7000 and the G20). I submit that the only reason anyone cares that much is that we can measure it and report on it.
I love the picture quality of this set in bright and low light environments. I didn't pay Kuro or VT25 money for my TV (not even close). If I did, I would be disappointed. When I look at what I got for my money, which is respectable black levels, excellent color fidelity and shadow detail, tweak factor, 3D, sexy package, etc. I think I came out ahead.
