What I mean is you (in effect) claimed the display would/could not do
justice to HD content because it cannot display it correctly even though
it has the "regulation" pixel count. Does that mean that anyone can
produce a display, and claim it is HD capable solely on the pixel count
alone, even if it cannot utilize all the pixels?
I understand all plasma screens must rescale content and therefore
may/will not utilize the total pixel count 100% efficiently.

Mine does not, nor does the next year's version of it. This
is the Panasonic PT40LC12. It has deinterlacing and 3:2 pulldown
and 3D decoding, as far as I know that's all. It does have
a "sharpness" control that can either be turned off or actually works
fairly well on some material.
Now the sound from the built-in speakers, that's a different matter.
It has a jillion ways to screw with it (incuding leaving it alone).

etc.
You could still use only 576 pixels vertically on 720p material,
as that is all that can be used for a 16:9 picture. Same for 1080i.
