Surely the article should be named e.g. List of image resolutions (since 'resolution' has different meanings - not necessarily image related). I don't think it needs to say 'common' (many of them are not common); it could possibly say 'standard' though, i.e. List of standard image resolutions, since all of them are defined standards. 80.47.80.101 14:00, 17 May 2007 (UTC)
I think a "list of standard resolutions" would be shorter than a "list of common resolutions." Btw, you would call these 'display resolutions' rather than 'image resolutions.' But, then, someone would come along and insert every bizarre resolution that ever existed (even more than are currently in here).
Should this be merged with display resolution? Madda 16:07, 12 April 2006 (UTC)
The table has little to do with "resolution" in the visual perception sense. It gives the grid patterns that pictures may be broken up into.
The table is very computer-world centric and reflects many different (and sometimes proprietary) solutions from individual companies and organisations rather than national and international standards.
There are some errors noted also that probably arise from confusion between compressed systems (eg MPEG) where the "active picture" line samples are given and uncompressed studio systems (in particular, 1.485Gbps HD SDI) where the number of samples per line also includes the blanking interval (- quite different for 50 and 60 Hz systems).
For example European HDTV entry in the table is wrong. Europe originally in the early '90s experimented with analog HD-MAC using 1250 line total, 1152 line interlace active picture (i.e. twice 625/576). Current DVB-S,-C,-T digital standards users from Europe, Australia, etc. are using or testing HDTV formats as listed in DVB's standard ETSI TS 101 154 V1.7.1 (2005-06) Annex A. (for a copy http://www.etsi.org/services_products/freestandard/home.htm ) In reality 3 HD formats (at 25 or 50 frames/s) are being broadcast or tested - 1280 x 720p; 1440 x 1080i and 1920 x 1080i - the latter being rare because the MPEG bitrate required is not available for low artefact pictures. Also most broadcasters use HDcam DVRs that have internal filtering to 1440 pixes per line. Note also that MPEG-2 uses 16 x 16 macroblocks but 1080 is not a complete number of 16 line samples - 1088 is, so the line number is sometimes quoted as 1088 although there's picture on only 1080 lines.--anon
Found 1280x768, for a 16:10 resolution. According to http://www.widescreengamingforum.com/wiki/index.php?title=Common_Widescreen_Resolutions it is 1280x800. There may be other mistakes...
The result of the proposal was merge.-- Jorfer 01:03, 18 July 2007 (UTC)
I suggest that the suffixes "i" and "p" on some resolutions could use explanation. PeterWise9 ( talk) 17:04, 18 January 2008 (UTC)
The 'i' and 'p' are for 'interlaced' and 'progressive scan.' An interlaced image's odd-numbered lines are displayed first, then the even-numbers are displayed on the monitor's next refresh. A progressive-scanned image would display the entire image at once. However, while downloading, they would be displayed, appearing progressively downward, however, in an interlaced image's odd-numbered lines would still be displayed first. Also, an interlaced video's odd-numbered lines would be displayed in the first, even in its second, odd in its third, and so on. Doggitydogs ( talk) 20:28, 19 April 2008 (UTC)
My pc lists 1920x1440 as a standard 4:3 resolution, should it be on this list? —The preceding unsigned comment was added by 85.133.27.147 ( talk) 15:21, 5 December 2006 (UTC).
Where is 1280x768? That's a common resolution on laptop computers using WXGA+. -- 65.8.156.221 19:17, 17 December 2006 (UTC)
Wasn't 1280x960 in the listings until recently? That's preferred for 4:3 monitors over the more common 1280x1024, I thought.
The "Display Aspect Ratio" column appears to assume a square pixel aspect ratio. A lot of these display formats do not have square pixels. Notably, 480-line CCIR 601 based formats have pixels shaped as 10:11 rectangles, the 320x200 PC formats are 5:6, and formats based on half the width of an NTSC subcarrier cycle (such as Apple IIe hi-res video) are 6:7.

I think it's a mistake to convert some of the aspect ratios to lowest terms. In particular, the ratio referred here as 8:5 is far more widely known as 16:10.
But I don`t think converting the aspect ratios to lowest numbers is a mistake because 16:10 is just a marketing term, it is used by some sales representatives to swindle customers that 8:5 is better than 16:9. UU ( talk) 21:17, 25 October 2009 (UTC)

NTSC's resolution 640 x 480 non-square pixels (like a television), giving a 720 x 480 pixel image when resampled for square pixels (like a computer monitor). PAL is 640 x 576 non-square pixels.

First should be listed the actual resolutions, organized by ratio. Each ratio should be listed and then common resolutions for that ratio listed with it. As such, the article would actually be about Common Resolutions not common devices, historical devices, and manufacturer specifications.
This article is, as it stands, not helpful to those who are searching for an actual list ofList of common resolutions. E.G. finding an actual spread on 16:9 resolutions so I can, precompression, format an RBG raw avi from 1080p to a lower resolution made me scroll through most of the article and then search to find useful information.

There are a lot of entries on this list that do not have sources and appear to be uninformed guesses. For instance, all computers that produce NTSC video at low resolution and are capable of artifacting have the same pixel aspect ratio, because they have to be producing pixels with the same dot clock that is twice the color subcarrier (7.14MHz). Yet, we have on this page:
This is nonsense. All three of these devices have the same PAR in NTSC. The Atari 400/800 entry is also doubly wrong because it overlooks that NTSC and PAL Ataris have different pixel aspect ratios -- PAL is nearly but not quite square pixels while NTSC is most definitely not, as anyone who has tried to draw a circle on an NTSC machine can attest. One source of these errors is that the page template computes the PAR from the SAR and the DAR, and while the SARs are generally correct, the DARs are often wrong, such as 4:3 for Apple II hires. This derivation is backwards. Often the only verifiable and reliable fact is the dot clock (pixel clock), which must be compared against the accepted square pixel clock for the video standard to derive the PAR, and then the PAR and SAR can be combined to derive the DAR. For Apple II hires this gives a DAR of (5:6) * (280:192) = (175:144).
I would like to fix these errors, but I can't do so without falling under original research.
The Commodore 64 VIC-II Hires entry also appears to be wrong. It is listed as having the same PAR as the Amiga and Apple IIgs, but an NTSC C64 uses a faster dot clock of 8.18MHz instead of 7.14MHz. Also, again, NTSC and PAL C64s differ. This page uses a dot clock based methodology and derives a PAR of 0.75:1 for an NTSC C64, not 0.833:1: http://hitmen.c02.at/temp/palstuff/

The title is "List of COMMON resolutions", so why does it list the resolution of every single display under the sun? Who cares that the Nokia E90 Communicator had a 25:11 SAR? Look, I just breadboarded a 3x3 LED matrix, do I get an entry now?
Someone needs to take an axe to this chart.

Why abusive use of commercial denominations, when the table is clearly technical?Wikipedia is not a technical publication and the Manual of Style does not mandate the use of coprimes for expressing ratios (see MOS:RATIO).

The Atari 400/800 entry is also doubly wrong because it overlooks that NTSC and PAL Ataris have different pixel aspect ratios -- PAL is nearly but not quite square pixels while NTSC is most definitely not, as anyone who has tried to draw a circle on an NTSC machine can attest. One source of these errors is that the page template computes the PAR from the SAR and the DAR, and while the SARs are generally correct, the DARs are often wrong, such as 4:3 for Apple II hires. This derivation is backwards. Often the only verifiable and reliable fact is the dot clock (pixel clock), which must be compared against the accepted square pixel clock for the video standard to derive the PAR, and then the PAR and SAR can be combined to derive the DAR. For Apple II hires this gives a DAR of (5:6) * (280:192) = (175:144).
I would like to fix these errors, but I can't do so without falling under original research.
The Commodore 64 VIC-II Hires entry also appears to be wrong. It is listed as having the same PAR as the Amiga and Apple IIgs, but an NTSC C64 uses a faster dot clock of 8.18MHz instead of 7.14MHz. Also, again, NTSC and PAL C64s differ. This page uses a dot clock based methodology and derives a PAR of 0.75:1 for an NTSC C64, not 0.833:1: http://hitmen.c02.at/temp/palstuff/

The title is "List of COMMON resolutions", so why does it list the resolution of every single display under the sun? Who cares that the Nokia E90 Communicator had a 25:11 SAR? Look, I just breadboarded a 3x3 LED matrix, do I get an entry now?
Someone needs to take an axe to this chart.

All of the 16:10 resolutions are improperly labeled as 8:5. I think it may be a bug with the mediawiki software itself. — Preceding unsigned comment added by 49.213.18.119 ( talk) 01:23, 18 January 2017 (UTC)

Why the aspect ratio of some devices is shown as 21:9, when the reduction to coprime integers demonstrates that the ratio is 64:27?
Why abusive use of commercial denominations, when the table is clearly technical? — Preceding unsigned comment added by 190.102.147.249 ( talk) 13:37, 23 November 2018 (UTC)
Why the aspect ratio of some devices is shown as 21:9, when the reduction to coprime integers demonstrates that the ratio is 64:27?Which devices, exactly?
Why abusive use of commercial denominations, when the table is clearly technical?Wikipedia is not a technical publication and the Manual of Style does not mandate the use of coprimes for expressing ratios (see MOS:RATIO). Further, spurning widely used notations like 16:10 and 18:9 as "commercial" or "marketing" and calling their use in Wikipedia articles "abusive" is counter-productive. Indrek ( talk) 13:58, 23 November 2018 (UTC)
I'll try and address the arguments for using 2:1 over 18:9 that have been put forth so far in various comments and edit summaries, as I understand them:
I would like to ask the anon(s) pushing the 2:1 notation to seriously consider how it actually improves this article and others, when readers are significantly more likely to encounter 18:9 elsewhere. Indrek ( talk) 20:39, 26 November 2018 (UTC)
The article seems to be missing the Amiga SuperHiRes resolutions.
