It can accept a 1080p signal, but its resolution is 1280 x 1080
see Hitachi website for specs
http://www.hitachidigitalmedia.com/DMG/viewProduct_1.jsp?productid=570
the electrode pulse is double that of the input signal
though the difference is clear when feeding an alis panel an interlaced signal then a progressive one
hope this helps
I don't think it does display every pixel at a given time (540 at one point), because it's ALiS. I think it 'supports' or 'accepts' a 1080p signal, but displays it as 1080i.

I think so.
Just tell me, why 42PD9700 does not accept 1080p signal ?
Where is the clue ?
--------------------
To Hitachi Digital Media,
Thanks for your reply. I've looked through the brochure and it only states 1080 as an input signal - but does not include p (progressive) or i (interlaced). I understand the 9700 can natively display 1080i, but am still confused to whether this model will accept a 1080p source.
Thanks Again For Your Time.

No, there is no official standard written for 1920x1080p by EICTA the HD Broadcast standards organisation. The only HD Standards that exist are 720p50/60 and 1080i50/60.
This years model the 42PD9700 will be 1024x1080.
Image differences in 1080i and 1080p, to the naked eye, would not be noticable.
1080p does not have more lines than 1080i. Simply put, 1080p displays all 1080 lines at the same instance where as 1080i takes the odd lines then the even lines and displays them to display the full 1080 lines.
--------------------
The Picture Master chip doesn't interfere in any way with display processing, and the same happens in a 42PD8600/8700 (no picture master here) as in a 42PD9700 Feeding a progressive signal gets a better picture, for both
A progressive signal does'nt mean that the picture is there as if you are looking at a painting
In a progressive signal the data is sent a whole lot to the screen at a certain frequency, say 60hz In an interlaced system the picture is sent in two parts In Alis first you have the even horiz axis illuminated and then the odd horiz axis illuminated at 120Hz (if i'm not mistaken)
Please don't start the Alis debate again, but you can try it yourself trying a DVD first with an Interlaced signal then with a progressiove one on a 9700
just tell me how is it possible ???
It is "your own eyes" evaluation, I suppouse.
If we feed 1080i and 1080p signal to device which can display only interlaced picture, it won't be possible to see any difference.
If it really does refresh at 120Hz then each 60th, you're getting 2 lines from a single original frame lit instead of 1 line from a field then 1 line of guesswork.
...540 electrodes can lit only 540 horizontal pixels in the same time, no more.

Mathematically that's correct, but subjectively your eyes would see a sharp 1080 picture, not 2 x 540 images jumping up and down.

Also must hope that quality control is better in the new plant in Czech Republic than it was in Turkey.
does this help/hinderthe discussion?
Panels were always made in Japan at the FHP plant, apart now from the Czech-made 50" I guess Assembly only, of some models took place on Turkey Surely the 6600 was one of them
All in all if you peep through the ventilation holes on any Hitachi model you can notice the panel factory information on the upper right side, looking from behind
Cheers
