Scusate ma avete letto bene la recensione all'argomento livello del nero, forse vi è sfuggito un simpatico box che funge da disclaimer(? non saprei come altro definirlo), ovvero il livello del nero è 0,02cd/m2 dopo la calibrazione ma.....
oppppsssss... negli USA si sono accorti (anzi DNice di avsforum si è accorto scatenando l'inferno) che quel livello di nero è una truffa di Panasonic perchè non si mantiene nel tempo. (come ammesso anche da Panasonic).
Il recensore mette in guardia che "forse" il fantastico nero più volte citato nella recensione sarà fantastico per un tot di ore poi il G20 diventerà un G10 poi un PZ80 poi chissà un Mivar?
Occhio.... Il G20 resta un televisore mediocre con un livello di nero ottimo da nuovo e medio(cre) dopo 1500 ore
Copio Incollo la parte di articolo:
Black Level
Idling luminance (and calibrated black level) was measured to be 0.02 cd/m2 on the Panasonic TX-P42G20 HDTV, although whether or not this figure can be maintained over time remains uncertain (see boxed explanation). When powered on from standby, or when a DVD/ Blu-ray disc is being loaded, the plasma television would display a lighter black level of 0.05 cd/m2 for about 1 second before settling at its idling luminance.
Our Panasonic TX-P42G20 sample did not exhibit any black level fluctuation in its [Cinema], [THX] and [Professional] viewing modes.
(fin qui tutto bene ma.... legete cosa segue...)
A number of USA owners of Panasonic’s 2009 plasma models have reported a sudden rise in black level on their plasma TVs after 1000 to 1500 hours of use. In an email response to CNet USA’s queries, Panasonic USA confirmed that the black level on their 2009 plasmas can brighten over time as a result of automatic internal voltage adjustments which kick in at set intervals to maintain optimal picture performance throughout the life of the TVs.
Panasonic USA went on to state that the newest (2010) Viera plasmas will incorporate an improved algorithm to apply the voltage adjustments in smaller increments so that any change in black level over time is going to be more subtle.
Should you be concerned when buying a 2010 Panasonic plasma television? Our opinion is “no” for the following reasons:
* While there exists a handful of subjective anecdotal reports, at this time of writing there is no concrete evidence showing that European and British sets are similarly affected by this loss in black-level performance; and
* Measurements on a couple of American 2009 samples suggest a threefold rise in black level after 1500 hours of use. Assuming that the black level on the Panasonic TX-P42G20 will increase by the same factor, it’s still going to be a respectable 0.06 cd/m2 which is generally adequate to produce deep blacks.

Fantastico Un Disclaimer in una recensione!!!!!
Come a dire, o non ve la prendete con me se tra qualche tempo il vostro G20 avrà un ottimo livello di..... grigio
