720P VS. 1080P

When TV's are listed as 720p I assume they also have 1080i...is this
correct?

Also, if you have 2 TV's side by side, one with 1080i and the other
with 1080p, is there a SIGNIFICANT difference?

Thanks!

usually, but not all. *most* 720 TVs will accept a 1080i signal and
display it at 720p, some can also accept a 1080p signal.


Also, if you have 2 TV's side by side, one with 1080i and the other

presumably, the 1080p would look smoother. you'd want to watch sports at
720p instead of 1080i. if your TV is 720p, it will never display 1080i,
just be able to accept it as a signal - it will be displayed as 720p.

the important question to ask is whether or not there's a SIGNIFICANT
difference between 720p and 1080p. If you're looking at sets of 42" or
smaller, the answer is 'no'.

No - they will take it, but to fully display a 1080i signal you actually
need a 1080p set.

with 1080p, is there a SIGNIFICANT difference?




i'd say so - especially on a larger screen - get to the shops and make your
own decision.

It is important to point out that this depends on the source. Aside
from HD-DVD or Blu-Ray, what 1080p content is out there? Any? Take
HD broadcasts, for example. They are either 720p or 1080i.
Therefore, no, you won't see a difference in this case, other than the
quality of the TV.

While apparently no broadcaster has yet done anything other than these 2
formats, the ATSC standard does define 36 different formats, almost half
of which would be considered high definition. For example one of the
unused formats is 1080p24. That would be great for classic film movies.
I would at least hope TCM (cable/satellite) would go with 1080p24 when
they go HD. I've noticed a lot of the interviews they do appear to be
shot in 24 fps while also appearing to be video. So maybe this is their
plan. Or maybe it's just to give it all a movie feel.

1080p60 could be done over cable, satellite, or Blu-Ray. It would most
likely only be used for premium sports channels.

The Hitachi 1080 isSTUNNING --at a great price. Far cheaper than a
Panny or overpriced Sony.

It depends what you mean by "have 1080i". There is a difference between
the signals a set can accept and what it can actually display at its
native resolution. If a set can actually display a 1080i picture -- 1920
x 1080 pixels -- it will be advertised as a 1080 rather than a 720 set.
Most 720p sets can accept 1080i signals, but they must scale them down
to their native resolutions, potentially losing some visual detail.

In any case, many retailers and even some manufacturers use the "720"
and "1080" designations carelessly. Most 42 inch plasma sets cannot
display a true 720p picture, and Hitachi uses an "HD1080" designation
for sets that cannot display a true 1080 picture. As most current sets
can now handle just about any signal currently in use, the important
number is the native resolution, expressed in horizontal by vertical
pixels.

JVC DLA-HD100 1080p supports 1080p24, 1080p50
and 1080p60 at 600 lumens -- bit high priced
but that might come down

How can 1080 lines fit into 720 lines?

Also, if you have 2 TV's side by side, one with 1080i and the other
with 1080p, is there a SIGNIFICANT difference?

Why don't you go to a ****ing store and look for yourself, cretin?

Fred,
You are always so helpful when someone needs information.
Oh, don't forget to renew your prescriptions before they run out.

It would hardly matter, as he's clearly not taking the meds.

Wow, re-reading my post, I sounded confrontational, which I didn't
intend. I really was asking what other 1080p content is out there
besides HD-DVD and Blu-Ray.

Some people had mentioned other format standards, but does anyone see
broadcasters using up the bandwidth for 1080p broadcasts in the
foreseeable future?
