"True High Definition" is meaningless marketing poop and should not be here. Mirror Vax 10:46, 5 Jun 2005 (UTC)
they both have duplicate paragraphs, maybe they should just be combined into one entry.
==> in the range of quality, 1080i is far from 1080p ; one could see 1080i collapsed with 540P, with 720P in between... Also the field rate is important, as flicker artifacts are reported in 1080P24 but not in 1080P59.94 or 1080P60. The Motion Picture industry that could not afford paying for Douglas Trumbull's Showscan was limited to 24fps, with its stroboscopic effects (e.g. spokes rotating backwards, etc...), and then the main reason behind Blu-Ray & Microsoft WMV-HD 1080P24 limit. As much as one would like 1080P60, most agree that artifacts even with the best 2:3 pulldown do not bode well for 24fps material, so even if one has a whole 1080P60 chain [Sony/Dalsa/Kinetta 1080P60 camera, native 1080P60 display], there is still a concern about the 1080P24 display flicker. One could double-flash the frame, so I don't think it's desperate, but the whole 1080P60 origination business is at stake until some Blu-Ray MPEG4 1080P60 can be produced. Microsoft might be able to raise the cap in WMV-HD as well.
Why are 1080p and 2:3 pulldown being mentioned in the same sentence? 2:3 pulldown only relates to frame rate conversion between 24 and 30 frames whether in 1080 or 720 or standard defintion. Sony has a progressive format that is refered to as psf or progressive segmented frame. Which only says that in laying the progressive frame to tape they dump one half (odd lines) to one field and the other half of the progressive frame (even fields) to the other field. If you have aquired footage shot in true interlace 1080i it will never become progressive in the same sense, because each field is it's own moment in time and is displaced from the previous field and the one ahead by the same duration.
In regards to 24 frame flicker, this is a throw back to the flicker of movie theatres, remember those, where audiences were literally entranced by the flashing of the screen. Some people believe this is a desirable effect...:>
I can see some merit in mentioning capabilities specific to manufacturers. The Samsung comment of accepting 1080p was added by soeone other than myself. I put in the capabilities of the Mitsubishi TVs because they were mentioned in the 2005 CES sentence, and to have a more fair representation than only one brand gaining extra mention.
I'm opening this discussion because this seems like a slippery slope. Should brand-specific information be removed altogether from this section, or limited in some way before even more people come along to make it even more comprehensive? Or should it stand since it's new information and technology, and the issue reevaluated when 1080p sets become more common and the list gets more out of hand?

Why isn't anyone broadcasting at 1080p (24fps and 30fps) even though it's an ATSC standard (see http://www.atsc.org/standards/a_53e-with-Amend-1-and-2.pdf ), and has been since ATSC was conceived (not a late addition, see Internet Archive --> atsc.org 1996 for example). Every television with an ATSC tuner (practically every digital TV in the US for example) supports 1080p at film frame rates. I don't know about cable or satellite tv, but it would be logical to broadcast movies and many television series over the air as 1080p in the US instead of degrading quality by encoding interlaced. Or is the article wrong in stating that no one broadcasts in 1080p? What about other standards than ATSC? I live in a country without HDTV so I can't check the bitstreams myself. Totsugeki
Can someone clarify this section? It doesn't make any sense. -- 24.249.108.133 16:48, 1 March 2007 (UTC)
I don't see anyone above yours, suggesting the section get removed. 1080i article is focused on the interlace. QXGA is for computer work and people don't sit far away, 70mm is an analog technology used in big theaters. I've pointed several people to this section and they have thanked me for the info. Daniel.Cardenas 21:31, 5 May 2007 (UTC)
How do you define clearer? It won't be clearer to a person looking at a 32" inch screen 10 feet away. The section has references that show the average person can't tell a difference after a certain size screen and distance away. That is fact based on research and that is what the section says. Also consumer reports published an article saying it isn't better for typical viewing distance and size. That again is fact based on research. You will have to describe under what circumstances it is better. If you think it is better under all circumstances than you haven't checked the facts. Daniel.Cardenas 15:42, 15 May 2007 (UTC)
But regardless of viewing distance, the quality is still there. If you walk past the screen, or walk right up to it, or gather around the screen really close to play split screen videogaming, the quality is actually there. Even if you are a thousand miles away from the screen, the quality will still be there. Like I said, this simple fact is often lost in the debate over if you can tell the difference or not, it makes people think that there is no difference, which is incorrect JayKeaton 01:54, 16 May 2007 (UTC)

I know it is not really that important, but 720p is higher resolution than 1080i. 1080i is only higher than 720p in spatial resolution (pixels per frame). It has a lower temporal resolution though than 720p (pixels per second). Granted people notice spatial resolution more than temporal resolution, but it still makes the sentence in this article not quite accurate. Minor point, but no one else seems to have mentioned it.-- 66.102.196.40 03:38, 20 August 2007 (UTC)
I am looking at the sony home cinema projectors. some are labeled "full HD 1080p compatibility" (eg VPL-AW10) others say "Full High Definition 1920 (H) x 1080 (V) resolution" (eg VPL-VW100). this looks to me like a marketing trick. should this be noted on this page? -- 87.127.117.246 14:48, 21 August 2007 (UTC)
According to the article: "The term usually assumes a widescreen aspect ratio of 16:9, implying a horizontal resolution of 1920 pixels. This creates a frame resolution of 1920×1080." So, what resolution is 1080p fullscreen content delivered at? Is it 1440x1080, 1920x1080, or something different? I ask because DVD's are 480p and the resolution is always 720x480, which is then resized to either fullscreen or widescreen. -driver8
Two problems here: 1) The citation actually does not mention 1080i at all 2) It is a misleading statement
There is a lot of misunderstanding, often helped along by misleading marketing in the HD space. By saying 1080p and 1080i are the highest-resolution one could easily imply - incorrectly - that they are about the same. In fact most consumer product marketed as high-definition is either 720p/1080i or upscaling equipment that is used simply to present a decent version of lower-resolution material on high-res displays. We should try to clear up this confusion rather then add to it. Perhaps this might be a good substitute:
The high-definition consumer marketplace changes rapidly. Only in recent years has 1080p source material (links to Blue-Ray and HD--DVD) become available. Many high-definition products are sold today that display in the somewhat lower resolutions of 720p and 1080i or provide link:upscaling capability to display lower resolution source material on higher resolution displays. Most broadcast media high-definition material is at no higher then 720p/1080i format. The highest resolution format available on the broad consumer market is 1080p source material presented on 1080p capable TVs and displays.
1080p Native Resolution
1080p refers to a resolution standard but is also used to describe video equipment capabilities. For example, video equipment that upscales to 1080p takes lower resolution material and reformats it for a higher resolution display. The image that results is different from the display of original 1080p source material on a native 1080p capable display. Some displays with a native 720p resolution advertise that they can display high-definition 720p and 1080i resolutions. In this case a downscaling from the original 1080i image is applied for display on the lower resolution display. 1080p native resolution equipment is equipment that can present 1080p and 1080i resolution images in full detail without downscaling. 1080p source material (e.g. Blu-Ray and HD-DVD) and 1080p native resolution video equipment are both available in the consumer marketplace today. —Preceding unsigned comment added by 151.191.175.231 ( talk) 20:30, 8 January 2008 (UTC)

At some point this article should mention that most content is not 100% 1080p. All of the compression schemes mpeg2, vc-1, h.264 only use 1/4 of the color information, while trying to keep 100% of the luminance. The input to the encoders is YUV 4:2:0 format which only contains 1/4 of the color resolution. The only time you get 100% 1080p is from varied computer sources, such as viewing a still picture from a ps3 on your big screen. Daniel.Cardenas ( talk) 23:15, 2 April 2008 (UTC)
Would it not be appropriate to mention both the Xbox 360 and the PlayStation 3 as consoles capable of outputting 1080p, or use a less specific wording such as "some video game consoles"? —Preceding unsigned comment added by 68.185.255.125 ( talk) 00:24, 11 April 2008 (UTC)
The lede of the article currently says that "Full HD" is a synonym of 1080p. But I don't think that this is true. According to HD ready, "Full HD" is actually even weaker than "HD ready". As an example, this monitor is definitely not 1080p (it's not tall enough), but is labeled "Full HD". Can someone with more knowledge of this look into what's going on with these terms? — AySz88 \ ^-^ 20:26, 25 November 2008 (UTC)
I'm pretty sure that "Most 17" computer monitors that support 1280x1024 60hz" would display an 'Out of Range' or similar message if pushed to 1920x1080. Simply forcing a graphics cards output to a certain level does not make the monitor compatible. Also the frequency is 'Hz' not 'hz'
I agree, the first thing I thought when I read that sentance was "thats a stupid thing to say". If a monitor is capable of running at a resolution such as 1920x1080@60Hz, it should report so when it communicates its abilities over DDC.
My ViewSonic E70f (17" 16" viewable 1280x1024 60Hz) can display a 1920x1080 image reasonably well at a max of 60Hz. I wouldn't recommend it though cuz it causes the monitor to emit a high pitched squeel.
Some other information regarding PC monitors seems less then accurate or just incomplete. For example my ViewSonic G225fB (21" 20" viewable 2048x1536 85Hz) is more then capable of taking a true 1920x1080p signal. I run it at 1920x1440 and thats really no diffrent then 1920x1080 despite being a 4:3 screen. It just has black borders on the top and bottom. The black bar issue tends to be highly over rated. A 1920x1080 frame displayed on a 1920x1440 screen has no image loss so the black bars are irrelevant. It matters more on VHS and DVD when they physically cut into the available image size. The same is essentially true of 16:10 CRTs that can run at 1920x1200 or better. However those are rare.
However to achieve this without using a PC based solution such as a console HD-DVD player or HDTV tuner you must pass it through a device capable of padding the signal or using fixed aspect ratio timing or it will be distorted. In this case you must adjust the vertical size manually. Generalleoff 02:28, 15 October 2007 (UTC)
There should be some information here about the ways to capture HD content, the various cameras and chips available and how they relate to the different HD formats —Preceding unsigned comment added by 75.21.46.3 ( talk) 19:05, 9 December 2008 (UTC)
Ive got a ps3 80 GB version, and a good new HDMI cable. Ive tried to set my Ps3 at 1080p on my own almost brand new 42" 1080p TV, and it wont work. It only supports 576p, 720p and 1080i. Ive tried it on two other 1080p tvs, and the same result occurred. So the statement that Ps3 supports 1080p, is questionable. 83.108.193.157 ( talk) 02:23, 3 August 2009 (UTC)
The Computer monitor section mentions that some larger modern LCD monitors can display higher resolutions then 1920x1080. However, perhaps it should be noted the resolutions some common HD capable CRT's were able to reach such as 2048x1536.-- Senor Freebie ( talk) 05:25, 3 February 2010 (UTC)
One question that should be answered is how much Internet bandwidth (Mb/sec) is needed to reliably stream full HD. I read a bunch of websites and they seem to be unsure and contradictory. —Preceding unsigned comment added by 72.130.55.225 ( talk) 20:16, 22 August 2010 (UTC)
I came to this page to see what the resolution of "1080" is. What a vain, futile effort. The article is jam packed with information a broadcasting director would want to know, and nothing most other people would. The answer to my question was buried in a semi-relevant graph (that is, a graph tangentially relevant to the discussion on the page).
If I were to rewrite this page in one sentence, it would read "A marketing label for 1920x1080."

"1080p (professional) is similar to 1080i (inexperienced), but twice as good
1080i is interlaced, whereas 1080p is non-interlaced. which is only really relevent if you have a really old fashioned CRT monitor''"
It has been deleted, but please lock this if possible to prevent this from occurring again. Thanks ;).
-Vlad
The second point is absolutely correct and should not have been deleted. 1080i material is deinterlaced on Plasma and LCD displays so standard 1080i50 material is infact rendered at 1080p25 meaning that there is basically no difference in the end result.
160.83.32.14 ( talk) 09:12, 19 June 2008 (UTC)
There are some questions a history section should contain, like when was 1080 standardized, when was it first adopted (and for what), and what was the rationale in choosing 1080 lines (and not 1000 nor 1024 nor another number). 217.237.54.116 ( talk) 13:03, 2 January 2012 (UTC)
I don't see anything here or 1080i that wouldn't be better folded into High-definition television. What do you think? Khendon ( talk) 13:33, 8 December 2012 (UTC)
This article needs information on progressively scanned frames.
The "psF" does in fact refer to "progressive segmented Frame" and is a concept suggested for professional HDTV with 1920 x 1080. Below you may find an excerpt from "A Guide to Standard and High-Definition Digital Video Measurements" by TEKTRONIX:
"Segmented frame production formats Several formats in the scanning formats table are nomenclated 1:1sF.
(I would be more than happy to insert a table in .jpg format if I only knew how to do this...)
The “sF” designates a “segmented frames” format per SMPTE recommended practice RP211. In segmented frame formats, the picture is captured as a frame in one scan, as in progressive formats, but transmitted as in an interlaced format with even lines in one field then odd lines in the next field.
(I would be more than happy to insert another picture to illustrate the "psF" concept if I only knew how to do this...)
The assignment of lines is the same as in an interlaced system, but the picture is captured for both fields in one pass eliminating spatial mis-registration that occurs with movement in an interlaced system. This gives the advantages of progressive scan but reduces the amount of signal processing required and doubles the presentation rate (reducing 24 to 30 Hz visual flicker) in the analog domain."
Please get in touch with me at <kmatus4365@yahoo.de> so I can mail the pictures mentioned. — Preceding unsigned comment added by 212.152.197.235 ( talk) 00:51, 26 December 2013 (UTC)

I know it is not really that important, but 720p is higher resolution than 1080i. 1080i is only higher than 720p in spatial resolution (pixels per frame). It has a lower temporal resolution though than 720p (pixels per second). Granted people notice spatial resolution more than temporal resolution, but it still makes the sentence in this article not quite accurate. Minor point, but no one else seems to have mentioned it.-- 66.102.196.40 03:38, 20 August 2007 (UTC)
I am looking at the sony home cinema projectors. some are labeled "full HD 1080p compatibility" (eg VPL-AW10) others say "Full High Definition 1920 (H) x 1080 (V) resolution" (eg VPL-VW100). this looks to me like a marketing trick. should this be noted on this page? -- 87.127.117.246 14:48, 21 August 2007 (UTC)
According to the article: "The term usually assumes a widescreen aspect ratio of 16:9, implying a horizontal resolution of 1920 pixels. This creates a frame resolution of 1920×1080." So, what resolution is 1080p fullscreen content delivered at? Is it 1440x1080, 1920x1080, or something different? I ask because DVD's are 480p and the resolution is always 720x480, which is then resized to either fullscreen or widescreen. -driver8
Two problems here: 1) The citation actually does not mention 1080i at all 2) It is a misleading statement
There is a lot of misunderstanding, often helped along by misleading marketing in the HD space. By saying 1080p and 1080i are the highest-resolution one could easily imply - incorrectly - that they are about the same. In fact most consumer product marketed as high-definition is either 720p/1080i or upscaling equipment that is used simply to present a decent version of lower-resolution material on high-res displays. We should try to clear up this confusion rather then add to it. Perhaps this might be a good substitute:
The high-definition consumer marketplace changes rapidly. Only in recent years has 1080p source material (links to Blue-Ray and HD--DVD) become available. Many high-definition products are sold today that display in the somewhat lower resolutions of 720p and 1080i or provide link:upscaling capability to display lower resolution source material on higher resolution displays. Most broadcast media high-definition material is at no higher then 720p/1080i format. The highest resolution format available on the broad consumer market is 1080p source material presented on 1080p capable TVs and displays.
1080p Native Resolution
1080p refers to a resolution standard but is also used to describe video equipment capabilities. For example, video equipment that upscales to 1080p takes lower resolution material and reformats it for a higher resolution display. The image that results is different from the display of original 1080p source material on a native 1080p capable display. Some displays with a native 720p resolution advertise that they can display high-definition 720p and 1080i resolutions. In this case a downscaling from the original 1080i image is applied for display on the lower resolution display. 1080p native resolution equipment is equipment that can present 1080p and 1080i resolution images in full detail without downscaling. 1080p source material (e.g. Blu-Ray and HD-DVD) and 1080p native resolution video equipment are both available in the consumer marketplace today. —Preceding unsigned comment added by 151.191.175.231 ( talk) 20:30, 8 January 2008 (UTC)

At some point this article should mention that most content is not 100% 1080p. All of the compression schemes mpeg2, vc-1, h.264 only use 1/4 of the color information, while trying to keep 100% of the luminance. The input to the encoders is YUV 4:2:0 format which only contains 1/4 of the color resolution. The only time you get 100% 1080p is from varied computer sources, such as viewing a still picture from a ps3 on your big screen. Daniel.Cardenas ( talk) 23:15, 2 April 2008 (UTC)
Would it not be appropriate to mention both the Xbox 360 and the PlayStation 3 as consoles capable of outputting 1080p, or use a less specific wording such as "some video game consoles"? —Preceding unsigned comment added by 68.185.255.125 ( talk) 00:24, 11 April 2008 (UTC)
The lede of the article currently says that "Full HD" is a synonym of 1080p. But I don't think that this is true. According to HD ready, "Full HD" is actually even weaker than "HD ready". As an example, this monitor is definitely not 1080p (it's not tall enough), but is labeled "Full HD". Can someone with more knowledge of this look into what's going on with these terms? — AySz88 \ ^-^ 20:26, 25 November 2008 (UTC)
I'm pretty sure that "Most 17" computer monitors that support 1280x1024 60hz" would display an 'Out of Range' or similar message if pushed to 1920x1080. Simply forcing a graphics cards output to a certain level does not make the monitor compatible. Also the frequency is 'Hz' not 'hz'
I agree, the first thing I thought when I read that sentance was "thats a stupid thing to say". If a monitor is capable of running at a resolution such as 1920x1080@60Hz, it should report so when it communicates its abilities over DDC.
My ViewSonic E70f (17" 16" viewable 1280x1024 60Hz) can display a 1920x1080 image reasonably well at a max of 60Hz. I wouldn't recommend it though cuz it causes the monitor to emit a high pitched squeel.
Some other information regarding PC monitors seems less then accurate or just incomplete. For example my ViewSonic G225fB (21" 20" viewable 2048x1536 85Hz) is more then capable of taking a true 1920x1080p signal. I run it at 1920x1440 and thats really no diffrent then 1920x1080 despite being a 4:3 screen. It just has black borders on the top and bottom. The black bar issue tends to be highly over rated. A 1920x1080 frame displayed on a 1920x1440 screen has no image loss so the black bars are irrelevant. It matters more on VHS and DVD when they physically cut into the available image size. The same is essentially true of 16:10 CRTs that can run at 1920x1200 or better. However those are rare.
However to achieve this without using a PC based solution such as a console HD-DVD player or HDTV tuner you must pass it through a device capable of padding the signal or using fixed aspect ratio timing or it will be distorted. In this case you must adjust the vertical size manually. Generalleoff 02:28, 15 October 2007 (UTC)
There should be some information here about the ways to capture HD content, the various cameras and chips available and how they relate to the different HD formats —Preceding unsigned comment added by 75.21.46.3 ( talk) 19:05, 9 December 2008 (UTC)
Ive got a ps3 80 GB version, and a good new HDMI cable. Ive tried to set my Ps3 at 1080p on my own almost brand new 42" 1080p TV, and it wont work. It only supports 576p, 720p and 1080i. Ive tried it on two other 1080p tvs, and the same result occurred. So the statement that Ps3 supports 1080p, is questionable. 83.108.193.157 ( talk) 02:23, 3 August 2009 (UTC)
The Computer monitor section mentions that some larger modern LCD monitors can display higher resolutions then 1920x1080. However, perhaps it should be noted the resolutions some common HD capable CRT's were able to reach such as 2048x1536.-- Senor Freebie ( talk) 05:25, 3 February 2010 (UTC)
One question that should be answered is how much Internet bandwidth (Mb/sec) is needed to reliably stream full HD. I read a bunch of websites and they seem to be unsure and contradictory. —Preceding unsigned comment added by 72.130.55.225 ( talk) 20:16, 22 August 2010 (UTC)
I came to this page to see what the resolution of "1080" is. What a vain, futile effort. The article is jam packed with information a broadcasting director would want to know, and nothing most other people would. The answer to my question was buried in a semi-relevant graph (that is, a graph tangentially relevant to the discussion on the page).
If I were to rewrite this page in one sentence, it would read "A marketing label for 1920x1080."

"1080p (professional) is similar to 1080i (inexperienced), but twice as good
1080i is interlaced, whereas 1080p is non-interlaced. which is only really relevent if you have a really old fashioned CRT monitor''"
It has been deleted, but please lock this if possible to prevent this from occurring again. Thanks ;).

The second point is absolutely correct and should not have been deleted. 1080i material is deinterlaced on Plasma and LCD displays so standard 1080i50 material is infact rendered at 1080p25 meaning that there is basically no difference in the end result.

There are some questions a history section should contain, like when was 1080 standardized, when was it first adopted (and for what), and what was the rationale in choosing 1080 lines (and not 1000 nor 1024 nor another number). 217.237.54.116 ( talk) 13:03, 2 January 2012 (UTC)

This article needs information on progressively scanned frames.
The "psF" does in fact refer to "progressive segmented Frame" and is a concept suggested for professional HDTV with 1920 x 1080. Below you may find an excerpt from "A Guide to Standard and High-Definition Digital Video Measurements" by TEKTRONIX:
"Segmented frame production formats Several formats in the scanning formats table are nomenclated 1:1sF.
(I would be more than happy to insert a table in .jpg format if I only knew how to do this...)
The “sF” designates a “segmented frames” format per SMPTE recommended practice RP211. In segmented frame formats, the picture is captured as a frame in one scan, as in progressive formats, but transmitted as in an interlaced format with even lines in one field then odd lines in the next field.
(I would be more than happy to insert another picture to illustrate the "psF" concept if I only knew how to do this...)
The assignment of lines is the same as in an interlaced system, but the picture is captured for both fields in one pass eliminating spatial mis-registration that occurs with movement in an interlaced system. This gives the advantages of progressive scan but reduces the amount of signal processing required and doubles the presentation rate (reducing 24 to 30 Hz visual flicker) in the analog domain."

It mentions the sixth gen but not seventh/current gen consoles which I am almost certain are all capable of native/"real" 1080p. B137 ( talk) 19:54, 6 November 2015 (UTC)
