Are the Pioneer plasmas still the only ones that properly display 1080p/24? I'm looking to buy a 50" model by years end, and would like to spend less money if there is another manufacturer that displays this properly.

The Samsung FP-T 5084 / 5884 / 6374 all properly display 1080p24.

The Samsung FP-T 5084 / 5884 / 6374 all properly display 1080p24.Displaying 1080p/24 @ 60Hz isn't "proper";) It's best to just say they accept 1080p/24.

The Panny 65PF10UK manual says:

A) The unit accepts a 24 fps input and
and
B) The unit does NOT perform a 3:2 pulldown on a 24fps input signal
and
C) The unit displays 24fps signals at a 50hz or 100hz refresh rate (without 3:2)

Will the display of this signal type likely be equal to that of a unit that is doing a 3:2 pulldown, or will it likely be better (i.e. have less judder, etc.)?

Can anybody explain or guess how all of this is supposedly working together?

But will there be meaningfully less judder? Or is the 24fps signal handling on these units completely worthless?

if it is copying an extra frame to make 25 frames and then display it at 50hz (or 100hz), will that produce just a much notciable judder as doing a full/normal 3:2 pulldown? Or is there SOME degree of improvement from this method that Panny might be using???? Are there degrees of judder here?

seems worthless to me.

It's going to output 24 fames at 50 or 100Hz which is dumb IMO. Completely worthless.

But on Page 44 of the 65PF10UK manual (under the 3:2 pulldown section) it says that the unit's 3:2 pulldown occurs only on other, NON-24fps, input signals.

It states that NTSC/PAL signals are processed ONLY from an S-video input connection....

Are you sure it's not talking about reverse 3:2? (i.e. converting an interlaced signal to progressive?) It wouldn't need to apply 3:2 to a non-24fps signal (because it would have already been applied), it would need to use reverse 3:2.

But then it would still have to do a forward pulldown AFTER the reverse pulldown, no?

On mine, when I pump 1080p24 into the TV, it displays a 24Hz refresh rate... take that for what it is worth.

Creating a 25fps signal (which would easily then be displayed at the 50hz refresh rate of the unit) seems like it would create less judder than using traditional 3:2 pulldown from a non-24fps source. No? Maybe?

This seems to be one of the few ways that the PF10UK unit might work given the operating specs in the new manual.
