Ignore dynamic contrast ratio ratings.
by minimalist / September 30, 2009 11:24 PM PDT

They are marketing gimmicks that can mean anything the manufacturer wants them to mean. They could even turn the TV off and measure the black level against a full on white screen.

Static contrast ratios (ANSI method) on the other hand are a comparison between pure white and pure black signals displayed on the screen at the same time. This is a more accurate description of the real world contrast you can expect out of a given screen.

I supposed that since the two sets in question are from the same manufacturer it might be OK to assume the same standards were used... at least for the static figures.

However,

I'm still not sure I'd ditch a perfectly good TV just to get a higher specification. The author of that Home Theater article I linked to above claims that inflated contrast ratio numbers alone (and even those static ones you gave seem unreasonably high) are rarely a good reason to pay a lot more for a TV.

I'm sure it would be a great set. I'm just not sure it worth all the trouble and extra money. The difference might be very very subtle. Since I have a hard time actually believing those static numbers are not fudged in some way its hard to tell what the real world difference between the sets would be without seeing them side by side with the exact same calibration settings.

Agreed

In reply to: However,

The OP started another thread here where he indicates concern about black levels. That's certainly one feature that *has* improved IMO, at least a little, vs the older PZ80U series PDP. If he watches in a dark room it will be even more apparent. Agreed though, the numbers alone aren't worth throwing the baby out w/ the bathwater Wink

cheers,

I am tempted by Panasonic so called "Infinite Black"

In reply to: However,

I'am not interested in subtle differences,I need to know that there are big improvements in picture quality, especially black level before i spend more money on tcp50s1 and sell my th50pz80u plasma.

You will have to buy one and compare then.
by minimalist / October 1, 2009 9:34 AM PDT

Specifications can be manipulated so the only way to tell for sure is to buy one from someplace with a generous return policy and see for yourself. My gut tells me they difference would not be noticeable unless they were side by side.

By the way, its generally considered bad form to cut and paste the same response on two threads on the same forum.

Cnet reviews by David Katzmaier for tvs
by NOBLEBOBOY / October 1, 2009 11:56 AM PDT

Please read the reviews for these models here in cnet. David Katzmaier does a fine job when it comes to evaluating television sets.
Good luck to you!

Not helpful per se
by Pepe7 / October 1, 2009 12:26 PM PDT

Understand, the OP might have different enough viewing space from CNET that only a side by side comparison in the actual viewing space (which I recommend) gives you enough info to see if the upgrade is actually worthwhile.

Panasonic new Tv models
by cubist / October 1, 2009 1:05 PM PDT
In reply to: Not helpful per se

I'am being tortured by Panasonic's "Infinite black" ,NEO PDP,600Hz sub-field drive.Do they all create great picture,really better then on TH50PZ80U? I bought my Tv this year is it good enough to keep it without this new features or is good idea to sell it and by new model? I was thinking about THC50S1.Black level is really important to me!

You keep repeating...
by Pepe7 / October 2, 2009 12:01 AM PDT

...the same question. Buy it, take it home, set it up and compare with your own eyes to what you currently own. We can't be the judge of what jump in picture quality you may or may not perceive per se.

I looked at both in same showroom
by samkh / October 2, 2009 12:29 AM PDT

earlier this year when the older model was still available. The contrast looked equal to me and the biggest difference was reflection. S1 is less reflective so it tends to look better in ambient light. If you darken your room the PZ80U should be good.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
