Hi Def 1080i requirements??

[HaZ]

Apart from a Hi Def set top box, whaat resolution does a tv have to support
to output 1080i transmissions? Im looking at a LCD widescreen with 1280x768
res support. Would this be sufficient to support 1080i?

Cheers,

HaZ

a 1280x768 device will give better then SD, but not the full of what 1080i
or even 720p can achive.

Is there an LCD (or any monitor device) thats not progressive?

ie an LCD at 1280x768 would be 768p (widescreen) :-)

yes, old VGA moitors :-)

actually, you can half ignore my previous post, I had mis remembered the
width of 720p, I thought it was more then 1280, but it is 1280.
so the lcd in question can do 720p fully, but still can't do the full with
of 1080i which is 1920

Just heard that Sharp are releasing a 1920 x 1080 native res LCD in August.
mI would hazard a guess and suggest it is 45" diagonal.
This is to match native 1080i Hi-Def.

Actually, it's better than that. It's higher than 1080i, being 1080p. It
scales 1080i up to 1080p to match it's native res.

They have been around for some time. This one is just bigger.

There is no scaling, as both are 1920x1080.
And ALL LCD setups must deal with the deinterlacing.

Yes, that's true that all LCD must deinterlace (unless it's a progressive
signal), but I'm talking about the input signal that is line doubled
(scaled) to 1080p.

Yep - I think the poster was referring to the fact that a native progressive
device at 1080p will have a higher perceived vertical resolution than a
native interlaced device displaying 1080i. Kell factor and all that...

(This is the same justification for 480 line progressive plasmas being sharp
enough to display 576 line interlaced transmissions - though not 576
progressive - assuming the progressive transmissions aren't pre-filtered for
interlaced displays...)
