This is one of those questions where no one here probably has the technical ability to answer..
I'll go ahead and guess that 1080i is better, since it's been around longer.

sorry but 1080i is not better, 1080p is a better picture but you really wouldn't notice a ton of difference unless you have a 1080i and 1080p tv right next to each other. Go to Fry's and look at their TV's I am sure they have a 1080i and 1080p right next to each other for you to compare. But really there is not a ton of content out there that takes advantage of the 1080p so if your debating on spending that extra few hundred on 1080p versus 1080i, if you have the extra cash laying around either get a better 1080i tv or go with the 1080p. it is up to you. They have the same resolution it is just the way the TV displays the pixels in certain sequences. If you want more detail just go to google and type in "1080i vs 1080p"

i comes before p in the alphabet, so 1080i is better.

1080i = interlaced (pixels are interlaced together, this can cause rough edges in action scenes)
1080p = progressive scan (very smooth picture)
NOBODY broadcasts in 1080p because it would take up too much bandwidth. Most broadcast in 720p or 1080i.
HOWEVER, HD DVD and blueray dvd you will notice a difference with 1080p.
So if you are only watching hd broadcast, the 1080p is only money wasted right now.

It's just a scam by electronics companies to make you buy a new TV. After 1080p becomes the norm they'll come out with 1440i and then of course 1440p, then 1760i and p and so on. I'll just stick with my 13" RCA tube set.

1080p is better, it just requires more bandwidth ( hddvd/bluray ) than most techonoly uses today. 1080i has a tendency to cause slow updates due to the way it generates an image.

uhhhh..... NO 1080p is superior to 1080i if you know what you are looking for and if you have a 1080p source to compare to a 1080i source. please try again later.

There have been deadlines set before and the FCC didnt stick to their guns so Im kinda in doubt about the Feb 09' deadline. There are probably 10 million people still using analog televisions and just over one year before they basically have to throw their shit away....I just dont see it happening that soon.

Analog TV's will still work, they will just need a digital box to convert the signal, similar to how you need a cable box to watch cable if you area is digital and not analog cable capable.
There have been deadlines set before and the FCC didn't stick to their guns so I'm kinda in doubt about the Feb 09' deadline.
This new law was set because of September 11th and the inabilities to communicate, they are opening up a bunch of frequencies by going to a digital format. I doubt there will be much push back when the deadline comes around, I know that broadcasters are excited because of the features this opens up to them.

IMO 1080p would be better. I have a 62" Samsung DLP that is 720p/1080i and an LG Blu-ray/HD DVD player. Watched part of a movie on 720p, then the same part on 1080i. 720p was crisper/sharper looking, so I would think 1080p would be even better.
I have now reset the player to be 720p instead of 1080i, since I thought the 1080i would be better when I originally set it up.

why would you bring up a month old thread?
The reason they are doing it is to get all the government frequencies to be able to communicate between each other. By forcing tv to go digital, they free up all the analog bandwidth for their communications. Just because its digital, doesnt mean its high def.

Bingo.
I don't know how digital automatically equals hi-def.

You guys are forgetting that the PS3 also plays games in 1080p resolution (based on the game). So it's not just bluRay and HDDVD.

i actually brought up this month old thread, becuase my computer won't bring anything else up. for some reason, the board won't update. everytime i look at the board on my home computer, i have to look through month old threads. the only way i can post on the board is to use my computer at work, or my dad's laptop.

Blu Ray is not the only 1080p function on the PS3...games are as well. So simply mentioning blu ray in no way should encompass a PS3 or an XBOX.

it shouldnt look much better. Its a higher resolution but its interlaced where the 720p is progressive
Schargedcobra97
10-01-2007, 01:30 PM
more lines of resolutions should = better picture...
he's my 2 cents
only networks i'll watch in 720p are
espn, abc, fox.. b/c when i switch to 720p they do look better than 1080i (b/c they are broadcast in 720)
now discovery hd, cbs, nbc, hd network, etc all look better in 1080i (obviously b/c they are broadcast in 1080i)
that being said that's why i love CRT t.v's, b/c they automatically switch formats...

Schargedcobra97 - 1080i runs a higher resolution BUT its interlaced. The TV refreshes the image odd lines, then even lines... like 2 different pictures at the same time. 720p is a lower resolution but it goes in order. 1080i should be a bit more laggy/blurry when it comes to fast moving things like sports or action scenes. The picture wont be that much better UNLESS like you said, the TV is scaling 720p to 1080i

1080p = what the display produces. It simply means that the entire frame is displayed at once.
1080i is what an HD source such as an HD DVD will produce. Most good display devices will buffer the 2 interlaced frames and properly deinterlace them.
Jaggies can be caused by a poor processor in a cheap TV not properly decoding the film or '3:2' sequence - or 2:3 sequence if you want to get really technical..
Jaggies are also caused by a slow refresh rate on a cheap LCD display.

the older (first gen are 1080i).
93LXHORSE, you are partially correct, but the sources these days are 1080p and no scaling or converting is required, obviously if you have a 1080p source and a display unit that is capable of producing 1080p.... and 1080p isn't technically displayed at once, the lines are scanned in order vs. every other line (interlaced).
93LXHORSE
10-06-2007, 08:08 PM
Right, I understand. I meant that the frame was drawn one line after the other in order with 1080p rather than an even / odd 2 pass scan.
And.... my HD DVD is 1080i, I forgot about the true 1080p players that are out now.
And, I am no expert, but I do read, and I do own some fairly decent equipment. Certainly as much as I need for my current house !
