Sharp 65 inch LCD Panel - Update

[Ext User(Justin)]

Fark! Sharp in Sydney got a pre-release on Monday. It's massive. 1080i
looked fantastic (it upscales to 1080p). SD was only OK (as you'd probably
expect). Should be $25K & appear in the big shops by the end of the year.
Don't think you can get a VESA wall mount bracket for it.

eh? What could that possibly mean on a LCD?

Well, a 1920x1080 interlaced source gets converted & is displayed as a
1920x1080 progressive scan image. Pretty much the same as what it would mean
on any other display technology.

You mean it is de-interlaced, as is required on ANY LCD display.
Thats if indeed the source was interlaced. Even though HD broadcast
is interlaced, there is no processing needed in most cases, as the
source is film.

No, its not any kind of "scan" on LCD. That is a distiction which
applies to CRTs. This is why CRTs flicker and LCDs do not.

LCDs don't scan. It just aint possible to display interlaced fields.
And the word "upscales" is just sales bullshit in this context.

Tell me something this LCD display does that "1080i" ones dont.
The claim is ridiculous.

Ah, you got me. I was mixing my progressive scan terminology with
de-interlacing. Why do they use the 'p' when it comes to LCD's - shouldn't
it be 1080d?

That's true.

I didn't say that it did anything that others don't. It is bigger though.
Can all 1080 LCD's accept a 1080p source (like blue ray DVD)? This one can.

I guess 1080p would mean it accepts a progressive _input_ signal.
SO it refers to the input, not the display. Just like all those
so-called "1080i" CRTs and plasmas that really only show about 1024x768.

"progressive" also implies a higher frame rate - 60 fps in the US.
If your LCD pixel response is fast, AND you actually have some
material recorded at a high frame-rate (sports perhaps?) then it
could be useful.
But everybody seems to be happy with 24 fps movies, so I don't
see it changing any time soon.

Whats the point? The progressive output on the DVD player is for the
benefit of CRTs, to eliminate flicker. It just moves the de-interlacing
from your LCD-TV to the DVD player.
Or do you expect the Blu-ray to carry full 1080p 60 fps movies?
That might be nice for fast-action scenes, but I'm not convinced that
good interpolation of 1080i cannot be almost as good.
I think the bitrate and compression algorithm quality are more
important.
