How discernable is 1080p over 1080i ?

[Pilam69]

You CAN TELL THE DIFFERENCE. When I watch programs that input into my 1080p capable tv at 1080i there is a noticeable, difference. Mainly in scenes with a lot of action. Forget the #'s, believe your eyes.

If it is a 720/1080i set (I am assuming non-crt tube): the pixel count will be the same, usually 1368 x 768 whether it is a plasma or LCD panel.

If it is a True-HD, Full HD or 1080P set (all the same just depends on the company wording) then the pixel count will be 1920 x 1080, or double the 720/1080i set.

Ok..i have a 47WLT66A LCD Tosh panel and the manual says it has 1920(H) X 1080(v) dots.
Component Video input terminals are
480i, 480p, 576i, 576p, 720p (50/60 Hz), 1080i (50/60 Hz)
(These signal formats are converted to match the number of
pixels of the LCD panel.)
So does this mean that my panel is a True-HD given that it has 1920x1080 yet is only capable of doing a 1080i component video input?
note is LCD. and note too is 47"
So the way i see it....is it like...
(in order of PQ )

1. No Pixels: 1366 x 768 = can show 1080i video input or 720p
2. No Pixels: 1920 x 1080 = can show 1080i video input or 720p
3. No Pixels: 1920 x 1080 = can show 1080p video input or 720p

With 1 being the lesser of PQ and 3 being the best PQ.
from my understanding my Tosh LCD is thus No2 as it says (from the manual) it has 1920(h) dots x 1080(v) dots.

Is my assumption correct??

Based on your discription, your panel inputs a maximum 1080i signal and then the video processor converts the image to 1080p for display. You are watching 1080p however some info is processed information (not really there).

[dmwiley]

Shooweee!!! Soembody knows exactly what they are talking about. I'm back from a 7 day hiatus (read ban) after making a favorable comment about you know what, i.e., that other DVD HD format-just as irreverant as ever. Probably be gone again in a few days. But before I go, just want you to know that I own 2 Blu-ray players. However, that does not stop me from wanting to learn about the other unmentionable format-you know the one that will play the HD Matrix Trilogy DVD.

[CptGreedle]

Well wwelcome back but perhaps you should realize one thing befor eyou are banned again.... the forum is called "Blu-ray.com", not "HighDefinitionMediaDiscs.com"... you should try to focus on Blu-ray here.

That being said, I will leave you in peace to do what you like but you should have posted in an "Off Topic" post and not an existing Home Theater 1080p vs 1080i post.

[eastbay78]

Hey guys, I'm new to the blu-ray community but wanted to get some quick advice. I recently purchased a 32 inch 720p and an upconverting dvd player. Now that it's clear blu-ray has won the battle, I'm thinking about returning the dvd player and upgrading. But was it a bad decision to purchase the 720p tv? Will a blu-ray player be totally worthless without a 1080p tv???

But what about those of us who do have 1080i tubes? Do all Blu-Ray players have selectable output settings via the HDMI? What will the Blu-Ray movies look like on my 34" tube, which I LOVE, incidently. I have yet to see a digital display that looks as good as a CRT.

CRT will do 1080i, they can't do 720p or any p because the way they work. Yes I think ALL dvd & bd players let you pick the resolution output for hdmi.

Well, my CRT has much better blacks BUT also has crushing blacks that kill much of the shadow detail, I have tried everything & the tv does not have enough settings to tweek to get good shadow detail. My A2000 has no troubles with great shadow detail, but lacks the true blacks that my CRT has.

[ixlegitballinxl]

on my 52 sony lcd, 720p looks better then 1080i, and there is a huge diffrence between 1080 and 1080p. Get a 1080p tv, you'll have no worries then!


people usually downplay 1080p, when they dont have 1080p money

The difference from SD dvd to Blu-Ray 1080i is 100% better to me and I was watching my SD dvd's up converted to 1080i .

Youre sitting at 4 Picture Heights (2.25 screen widths) from your 1.78 wide 36" x 63" (73" diagonal) screen.
You probably can see about 850 x 1500 pixels from there reaching the limits of your vision, maybe more if you have sharp eyes.

Your 1080i input is being deinterlaced to 1080p by your DLP panel I would assume.

If it's being deinterlaced correctly (and the optics of the TV are up to it) you should be getting the 1080 x 1920 pixels already.

But you might not be able to resolve them fully or with sharp contrast from your sitting distance.

(My advice: sit closer )



In the case you determine the 1080i input is being deinterlaced with the simplest bob method (540 x 1920), well there might be an 1.25x improvement if you had a 1080p input/1080p output TV (or a 1080i input/correctly deinterlaced 1080p output TV) from your sitting distance as you can see minimally 850 vertical now and you'd would be getting 540 vertical. (Horizontally you wouldn't see any difference, if your curren't TV resolves 1920 now. You see about 1500 of those anyway) So if your mits is bobbing 1080i, a true 1080p would look just one step sharper.

Still, my advice: sit a little closer


ymmv

I keep reading on others sites that 720p is actually better then 1080i. I was just wondering what you guys here think is better. I have a 42" Sony Wega Rear Projection and want to know the better viewing option I have. Currently I have everything set to play in 1080i and love it. Will movies and games look better if I have it set to 720p?

[Filterlab]

From what I've read, Progressive is generally perceived to be better than Interlaced as the image is updated frame by frame rather than line by line apparently creating better motion.

Of course it depends on a vast number of factors; quality of cameras used, how well the disc has been mastered, type and quality of disc etc etc. I know that Plasma can only display Progressive images so whatever signal is fed (p or i), the display will change it to p, however I'm not sure about rear projectors.

At the end of the day set it to your favourite setting. Whether it's p or i then go with it and enjoy.

[Blue]

It depends.
720p is de-interlaced ready to at 1280 x 720

1080i can be de-interlaced to a very high quality at half the frame rate so 1080i60 equates to 1080p30 (not quite the same quality but close). The cheap way is to drop half the frames so it's 1920 x 540.

For fast moving sports 720p is supposed to be better as there can be a higher frame rate, but at the expense of resolution. I suspect this may come down to screen sizes etc as to which is the better

[i want HD movies]

Here we go again.... lol

you will read term papers dicussing the ads of each. Like it was said just pick the one that you like better (if you can honestly discern a dfference) and go with it.

The bigger difference I can see is how it was recorded. i.e. Discovery HD records in 1080i for great detail in panaoramic landscape shots, but some artifacting appears when you see movement. Whereas Fox uses 720P due to its strong sprts segment, but still shots do not look quite a clear.

Video games and the like will probably not show any discernable difference in quality. Boadcast tv has lots of pixelation due to the compression of the signal 720, 1080, 324 or whatever. Until the broadcasts are improved it wont make much of a difference.

On your set I think it woud be hard to tell the differecne. Dont worry about it. Just enjoy your set.

[calcajun]

Maybe it is my tv size but i just don't see how people can't see the difference.
My tv is 73" Mitsu diamond rear screen 1080I

For me, I watch one of the channels that brodcast 720p and it looks great (compared to 480P dvd).
Then i see something on another channel like PBS that is broadcast in 1080I or 1080P and the difference is huge. Everything is so clear and detailed where you can totally see fine hairs and lines on subjects. Then go back to 720P and it is just kinda little soft and fuzzy.

Again maybe it is my screen size that realy shows the difference but when i go from 1080 to 720 it frustrates and dissapoints me in the 720P broadcasts because i know how much better 1080 actually is.

For movies, there should in theory be no difference between 1080i and 1080p if the TV does its job properly:

However, some TVs do not properly process the 1080i signal, this article lists some that work properly and some that don't:

I think the whole problem is that most don't perform this process well (from what I heard). I can surely see the difference between 1080i and 1080p on my TV.

[vincent_hanna]

Folks--New to the board, and there seem to be some VERY knowledgable folks in here which is very cool. I have a new 65" Toshiba DLP, and a PS3, with Yamaha VX-2600 receiver. However, I have an important choice to make and need some expert opinions.

Would you a) Have 1080p picture with optical audio output or

b) Have 1080i picture with HDMI audio output

Thanks for your help

Ok, I just downgraded from a 1080p 42" LCD set to a 1080i 50" PDP set. My observations after 1 week. I wrote about this before, but I am changing my stance a bit:



Yes, I can see the differences in SOME things. Very slight, however, and not as much of an issue if you sit more than 10 feet away. I watched a few scenes on Casino Royale and specifically remembered certain details about the scenes, then compared them (albeit later) to my 1080i set. Here were my observations, which you can take with a grain of salt if you like, because of the differences in sets:

1. In the early scene where Bond is driving in the silver Ford car, and they cut to him viewing his cellphone, I was able to notice the poch-marks (sp?) in his face more easily with a 1080p LCD set. In 1080i, I don't see them in as much detail.

2. The grain in movies is more noticeable in 1080p, although this may be somewhat due to the differences in contrast technology between LCD and PDP.

3. On shots where you see someone close-up, there is virtually no discernable difference between the 1080p and 1080i image, EXCEPT in the fine details in the background.

4. When Bond enters the hotel and sneaks into the security room, I was able to read the SONY logo on the Blu-ray player during the medium shot at 1080p. In 1080i, this is much more difficult to see (we're talking about a darned small piece of screen here, but there is a difference).

5. In Planet Earth, when they showed the opening shots of the cattle in Disk 1, I was able to see the tiny cattle individually with greater detail at 1080p. At 1080i, the details have less of a "wow" factor. This difference is quite noticeable to me.

6. HD Video looks better at 1080p, although some games (like rub-a-dub) look better at 1080i. Weird... I know. It depends on the game, I guess, and native resolution, I suppose. Could be due to PS3 scaling issues, or TV scaling, I don't know.

So bottom line, yes, 1080p is better in the EXTREMELY fine details. Is it worth the extra cost? Hmm... depends on the person. Now that i've gone down to 1080i, I'm apt to say, "yes", where one week ago after initially getting the 1080i, I was saying, "no... they're not much different."

The bigger issue about 1080p is the 24fps capability. I'd get a 1080p set just for that (provided my TV could handle it.

[JeffHenry]

I was thinking of buying a 720p Samsung 32inch LCD, but I noticed it doesn't accept a 1080p signal, thing is, I have no idea what that means, can someone shed some light?
