1080p, 1080i or 720p

Which is the best?

1080p is obviously the best. Choose the highest resolution signal your television will accept.

Awwwwww.......1080 lines progressively scanned is a thing of beauty!

I'm sorry, but this is a dumb question.

Unless you are watching the content in question on a 20" screen or smaller (in which case barely any difference between them would be noticeable), 1080p is a LONGSHOT VICTOR.

I don't go as far as saying this is a stupid question because the OP may be someone who is obviously not familiar with the subject. Like someone's grandma

But I am really amazed that someone who would have the basic ability to search the internet, find this site, and start a forum discussion on the matter, would not already know this? I am amazed that anyone wouldn't already know this period. I think someone is trying to raz some berries.

2160p is the best. Just wait until 2010.

No question is dumb.

this stuff may be simple to us....

Go talk to someone about a flat panel. Try to present a fair pro/con, and then try to explain to them why they can't use coax, and why HDMI cable is better than RWY composite. (and why not to get the 150$ cable BB or the retailer pushes on you)

Watch their eyes glaze and their head explode


believe it or not, I still run across people who, although they own a PS3, think they need a standalone player for blu rays.

That's just not correct. Unless you have super human vision.

"The resolution of our eyes is 12 vertical lines per arc angle (one line per arcminute for 20/20 acuity) times 2. Now 28 degrees x 12 lines x 2 = 672. This means we really can't see a display component (pixel) smaller than 1/672 x image width. Our minimum resolvable element size is about 0.065", or about twice the size of the pixels of the WXGA image! Put bluntly, from 8 feet away while watching a 50 inch plasma TV, the human eye is generally incapable of reliably distinguishing any detail finer than that shown on a true 720p display! "

Okay. I think this would rapidly change when you move close to the display. Based on this, I expect one would see the difference between 720p and 1080P if they are about 6' from a 50" display.

That is based on the vertical resolution. How about the horizontal resolution 1280 vs 1920.

I disagree with the bolded statement. I own a 50" plasma and sit about 9 feet away. I recently got digital cable. I completely understand the situation with compression and overall quality in digital broadcasts, but consistently BD's coming in over the same HDMI input as my cable have much greater detail. I understand this is not a completely reliable comparison, but if there is an HD movie playing that I own, I am typically disappointed by the lack of quality as compared to the BD. While some of it is owed to the cable's bandwidth, the lower resolution picture definitely is distinguishable.

Bottom line is to judge the difference yourself and see if you can see it. I agree with the distance/viewing ratio having a large impact, as well as color reproduction/blacks, motion resolution and the like.

1080p
720p
1080i
althought 1080i has more actual resolution than 720p

1080i does not look right on my TV only 720p looks correct.

[genkifd]

1080p / i is the same quality for still images

progessive is better for fast moving images

so for still picture 1080p then 1080i then 720p

moving images 1080p then 720p then 1080i....

CRT tvs scale to 1080i, they can't actaully do 720p

Actually 1080i has less effective (vertical) resolution than 720p when fast motion is considered (e.g. action, sports and dancing)

Wow. I agree with some other posters, in that if you don't know the answer but were able to find this site and post a thread then you shoudl really already know this..
Ps.....I really hope you are kidding BTW.
Pss...........If your not serious, then to avoid further flaming on the forum, I would recommend hanging around the Newbie Forum til you get your feet wet.

Getting in on this a little late...

Since this is question turned out to be for displays, 1080p is designed to be the "best" (as we already know), which in turn will yield the "best" picture (allowing for proper distances, of course) for any given input signal (again, as we already know) in terms of resolution. The other levels (1080i, 720p) are technological compromises for bandwidth restrictions and cost.

The other half of the ballgame is the compression of the source material as it is received by the display.

For Blu-ray players, the bandwidth is limited only by the HDMI cable bandwidth and the Blu-ray player's internal electronic circuitry. With HDMI it should be possible to get a true, 1920 pixel x 1080 pixel, UNCOMPRESSED HD video image stream sent to the display (after decompressing the video off the disc).

All other transmissions will require some form of bandwidth compression. This is commonly seen as "1440" horizontal resolution used by cable companies and satellite providers instead of true HD "1920" horizontal resolution. While the image is still an HD image, i.e. 1080p (1920x1080), some of the high frequency content (mostly sharp edges and high speed motion) has been removed or reduced, producing the "1440" resolution. This is why a comparision between a screen capture from a recorded HD broadcast and a Blu-ray disc is not a fair comparison (unless the Blu-ray image is worse than the broadcast, as alleged in _Gladiator_ ). Companies do this to give themselves more possible "HD" channels (sound familiar?), but as consumers we're not getting the real stuff, only something really close.

So if you're planning to watch mostly Blu-ray movies, I would go with the 1080p sets. If it's mostly other stuff, you're not going to lose much by using a 1080i or 720p display.

Okay, everybody, you can wake up now, lecture over.

(And for anyone who asks, "Yes, I do have a EE degree" )

There is more to moving pictures than lines of resolution, so it's important to also find a display capable of accurate color reproduction. Just one more thing to keep in mind.

Indeed. It is lot more than resolution. But also resolution is extremely important.
