720 and 1080i?

Now, they are advertising different hdtv sets as one or the other.
What the f..k is the difference? I need to buy a set soon and i don't
trust the idiots called salesmen.

At 42" and below 720p will do fine, for larger screens you should get
1080i. These are native resolutions of the TVs. Pictures are transmitted
in various resolutions between 480i and 1080i. yOUR Set then converts it
to the native resolution. i stands for interlaced, p for progressive
scanning.

The more lines, the better the resolution (picture quality).

Right and 720P has 720 lines 60 times a second. 1080i has 540 lines 60
times a second.

1080i has more information and therefore has a harder time being
compressed and fitting into a 19 Mbps digital TV channel so you will see
more macro-blocking in fast action scenes.

When broadcasters are tempted to add more digital channels there is even
less room for 1080i and you get more macro-blocking. A lot of
broadcasters have solved this problem locally by taking 1080i network
feeds and converting them to 720P which introduces more artifacts.

Artifacts are something 1080i already suffers from more than 720P
because of the interlacing of lines that are from different times.

Most large screen DTV sets are native 720P to begin with. It is only
lately that 1080P sets have been introduced.

If you like 1080P and I do wouldn't it be nice if we could get it
broadcast? IMO 720P rocks as does 1080P. 1080i should have been still born.

Can't do 1080P with the crap modulation and codec we are stuck with here
in the US, 8-VSB and MPEG2. Can do in Estonia, France and China where
they are using DVB-T COFDM, DMB-TH TDS-OFDM and MPEG4.

But when your in a hurry and your corrupt politicians have to pay of
their lobbyist what can you do? Just have to accept it I guess.

Then why don't you go to Estonia, France, or China and stay there!

Bob for God's sake he was asking for help in buying a TV set not your
braindead propaganda. Screw off.

As to the original question, 1080i is a broadcast standard, TV sets are sold
in 720p or 1080p. 720p sets tend to be the cheaper ones, often smaller
sizes. 1080 sets tend to be bigger and have twice as many pixels. Whether
you can actually see those pixels depends on the type of input, the size of
the set and how close you are sitting.

If you expect to be watching a lot of standard definition broadcasting get a
720. If you expect to be watching mostly HD you might want to invest in a
1080. But bottom line it's your money and your tastes.

And it may be worth noting that 1080p sets are dropping quite a bit in price
this year. There's a new Toshiba 65" 1080p DLP set that's showing up at
retailers this month for about $2200 (and under $2K mail order), which is quite
inexpensive for a 1080p set that large.

Other brands are dropping as well.

Of course, the other question is whether or not you can actually see the
difference in your viewing situation. There have been a lot of articles written
on this topic. Here's one recent one:

If you're gonna be doing HTPC, a 1080p might be useful for the
additional screen real estate. Especially if it can do pixel to pixel
mapping at 1080.

Many places now have that set under $1800.

I think that would qualify as under $2K. g

Beach Audio (who are known for their shady business practices) offer it for just
under $1800. I would NOT recommend that anyone do business with them.

The cheapest price I've seen from a reputable online store is $1900 (NewEgg.com).

There are several other models in this same line that will be shipping soon at
even lower prices (a 50" and a 57" model).
