so was just thinking back and looked up the specs on my previous plasma screens.

my first plasma was a Panasonic TH-42PX60U

second was a Panasonic PC-P50S1

I bought my third plasma on Saturday. A Panasonic TC-P55ST60 - do not have it at home yet. Waiting for new shipment due Tue or Wed
with delivery scheduled for Thursday.

was just looking at the specs on all 3 and wow have we ever come a long way from the 42px. The ST60 is actually 2lb lighter than the 42.
I thought the picture quality of the first 2 was pretty good but comparing contrast ratio. wowza!!
Up to 10,000 to 1 (PX)
to 40,000 to 1 (S1)

to now 5,500,000 to 1 (ST)

I will be retiring a 40in Sony HX800 when the new ST arrives.

can't wait till Thursday. Can't recall.. where was the 50S1 placed on the Panasonic big scheme of things?
I seem to recall it was a step or 2 from the top end.

Tell me you don't really believe your new set has a contrast ratio of 5,500,000:1 rolleyes.gif

Just quoting what the specs for the 3 tvs that were on Panasonics website under Contrast.

i clicked on "contrast" on the web page and Panasonic says

"The ratio of dark to light in an image. When this ratio is large, contrast is high. When the ratio is small, contrast is low. "

if they are not the contrast ratio. what do the numbers mean? How else would i interpret 1:5,500,000?

i understood contrast ratio to mean
"As a general rule with contrast ratio, the larger the number the better. It is an expression of the difference between the blackest black and the whitest white the screen is capable of displaying"

so...google tells me these numbers are pretty much useless and meaningless. Might as well say the plasma is made from pixie dust and moonbeams.

Panasonic can specify the black level on dynamic mode, which uses floating black technique to claim higher contrast ratio. Basically makes the panel extremely dark with no image, well below being visible. Marketing bull-crap in other words. The black level is low on these panels is lower than the older ones, but not 100x lower. More like 2x to 4x lower.
