I've never noticed a green tinge to my own V20 (an early model) but otherwise your description is about right. Very dimly lit scenes can trigger the floating blacks - The Social Network is another offender. It's something you either get used to, or don't!
Re. plasma black performance generally, this has often been touted as being superior to LCD, but is this true any more? I certainly found it difficult to believe when I bought my previous plasma, a Panasonic PX80! The blacks on the V20 are far more impressive but better than a good LCD? It's hard to say. I have read though that plasmas are better at handling dark picture areas, i.e. retaining colour and detail in these areas.
I also believe (in my limited experience) that plasmas offer a more "natural" picture than LCD, although it's hard to say why this is so. They certainly seem easier to set up - we bought a small Samsung LCD for the bedroom and it has literally dozens of obscure picture settings to play with. My favourite was probably "Edge Enhancement" which by default was set to
On...
Floating blacks are not that much of a problem for me. Yes, there are few of them here and there, but nothing very distracting. The worst case I've seen so far was at the beginning of "The Dark Knight",
the one that user Craig uk was talking about, but, other than that, nothing significant.
It's difficult for me to talk about the different screens firsthand, because this is my first HDTV, and the only other that I spent some time with is my brother's entry-level Samsung 32C450 LCD. However, after all those great reviews that this TV got, I must admit I expected a slightly better blacks, or, rather,
blacks that would be more visibly better than those on other less expensive TVs. Like I said, I'm satisfied with the picture, but since that "infinite pro" black level is probably the main justification of this TV's premium price, I expected a bit more.
If all this talk about filters is true (i.e. putting filters in first supplies in order for the TV to get good reviews and then removing them afterwards in order to cut costs) then that really is one hell of a rip off.
Plasmas are definitely better in handling dark picture areas than even more expensive LCDs (more or less all reviews confirm this), not to mention viewing angles and, above all, motion resolution. If you want acceptable motion resolution on LCD, you'll have to buy some of the top-of-the-range models. Also, the picture is less "agressive" and therefore more natural, as you say. Probably the most beautiful pictures I've seen on my TV were those of the live coverage of New Year's concert from Vienna on German ZDF HD, via V20's in-built sat tuner. A true feast for the eyes. Somebody described HD pictures on this TV as "silky" and I think that describes them best: sharp but
smooth in the same time, without any edge jaggies or agressive lighting that is so typical of LCD TVs.
If the picture stays as it is now, I'll be perfectly happy with it.
Wish I haven't heard about those filters, though.
