Note that the groupings are not square.]] [[File:Samsung LE26R41BD and Yamada DVD player 20030624.jpg|thumb|An LCD television set with a 16:9 image ratio.]] '''16:9''' (1.78:1) is a [[widescreen]] [[Aspect ratio (image)|aspect ratio]] with a width of 16 units and height of 9. Since 2009, it has become the most common aspect ratio for [[television]]s and [[computer monitor]]s and is also the international standard format of [[digital television]] [[High-definition television|HDTV]] [[Full HD]] and [[Standard-definition television|SD]] TV. This has replaced the smallscreen [[4:3 aspect ratio]]. 16:9 (1.78:1) (said as sixteen to nine) is the international standard format of HDTV, non-HD digital television and analog widescreen television PALplus. Japan's Hi-Vision originally started with a 5:3 (=15:9) ratio but converted when the international standards group introduced a wider ratio of 5⅓ to 3 (=16:9). Many digital video cameras have the capability to record in 16:9 (=4²:3²), and 16:9 is the only widescreen aspect ratio natively supported by the DVD standard. DVD producers can also choose to show even wider ratios such as 1.85:1 and 2.39:1 within the 16:9 DVD frame by hard matting or adding black bars within the image itself. However, it was used often in English TVs in the 1990s. ==History== [[File:HDTV aspect ratio derivation.svg|thumb|<div style="margin-bottom:1ex;">Derivation of the 16:9 aspect ratio</div>The main figure shows 4:3, 1.85:1 and 2.35:1 rectangles with the same area ''A'', and 16:9 rectangles that covers (black) or is common to (grey) them. The calculation considers the extreme rectangles, where ''m'' and ''n'' are multipliers to maintain their respective aspect ratios and areas.]] Dr. Kerns H. Powers, a member of the [[SMPTE]] Working Group on High-Definition Electronic Production, first proposed the 16:9 (1.7{{overline|7}}:1) aspect ratio in 1984,<ref>{{cite|url=http://www.sportsvideo.org/new/wp-content/uploads/2013/10/Searching-for-the-Perfect-Aspect-Ratio.pdf|title=Searching for the Perfect Aspect Ratio}},</ref> when nobody was creating 16:9 videos. The popular choices in 1980 were: 4:3 (based on TV standard's ratio at the time), 15:9 (the European "flat" ratio), 1.85:1 (the American "flat" ratio), 2.2:1 (the ratio of 70&nbsp;mm films and [[Super Panavision 70]]) and 2.39:1 (the [[CinemaScope]]/[[Panavision]] ratio for [[anamorphic]] widescreen films). Powers cut out rectangles with equal areas, shaped to match each of the popular aspect ratios. When overlapped with their center points aligned, he found that all of those aspect ratio rectangles fit within an outer rectangle with an aspect ratio of 1.78:1 and all of them also covered a smaller common inner rectangle with the same aspect ratio 1.78:1.<ref name="Cinemasource">{{cite journal|url=http://www.cinemasource.com/articles/aspect_ratios.pdf#page=8|format=Technical bulletin|title=Understanding Aspect Ratios|journal=CinemaSource|publisher=The CinemaSource Press|year=2001|accessdate=2009-10-24}}</ref> The value found by Powers is exactly the [[geometric mean]] of the extreme aspect ratios, 4:3 and 2.4:1 (or 48:20 - see also [[21:9 aspect ratio]] - .∞:1) for more info), <span style="font-size:125%;font-stretch:80%;">√</span>{{sfrac|47|15}}≈1.78:1 which is coincidentally close to 16:9. Applying the same geometric mean technique to 16:9 and 4:3 yields the [[14:9]] aspect ratio, which is likewise used as a compromise between these ratios.<ref>{{cite patent|title=Method of showing 16:9 pictures on 4:3 displays|country=EN|number=5956091|gdate=1999-09-21}}</ref> While 16:9 (1.7{{overline|7}}:1) was initially selected as a compromise format, the subsequent popularity of HDTV broadcast has solidified 16:9 as perhaps the most important video aspect ratio in use.{{Citation needed|date=October 2009}} Most 4:3 (1.3{{overline|3}}:1) and 2.39:1 video is now recorded using a "[[shoot and protect]]" technique<ref>{{cite journal|journal=EBU|location=[[Switzerland|CH]]|url=http://www.ebu.ch/en/technical/trev/trev_280-baker.pdf|title=Safe areas for widescreen transmission|first=I|last=Baker|publisher=BBC|date=1999-08-25|accessdate=2009-10-27|format=PDF|archive-url=https://web.archive.org/web/20101011055023/http://www.ebu.ch/en/technical/trev/trev_280-baker.pdf|archive-date=2010-10-11|url-status=dead}}</ref> that keeps the main action within a 16:9 (1.7{{overline|7}}:1) inner rectangle to facilitate HD broadcast{{Citation needed|date=October 2009}}. Conversely it is quite common to use a technique known as center-cutting, to approach the challenge of presenting material shot (typically 16:9) to both an HD and legacy 4:3 audience simultaneously without having to compromise image size for either audience. Content creators frame critical content or graphics to fit within the 1.33 raster space. This has similarities to a filming technique called [[Open matte]]. After the original 16:9 Action Plan of the early 1990s, the [[European Union]] has instituted the 16:9 Action Plan,<ref name="actionplan">{{cite web|format=legislation summary|url=http://europa.eu/legislation_summaries/other/l24103c_en.htm|title=Television in the 16:9 screen format|publisher=Europa|location=[[Europe|EU]]|accessdate=2011-09-08}}</ref> just to accelerate the development of the advanced television services in 16:9 aspect ratio, both in [[PAL]] and also in [[High-definition television|HD]]. The Community fund for the 16:9 Action Plan amounted to €228 million. In 2008, the computer industry switched to 16:9 from 4:3 and 16:10 as the standard aspect ratio for monitors and laptops. A 2008 report by DisplaySearch cited a number of reasons for this shift, including the ability for PC and monitor manufacturers to expand their product ranges by offering products with wider screens and higher resolutions, helping consumers to more easily adopt such products and "stimulating the growth of the notebook PC and LCD monitor market".<ref name="display">{{cite web|url=http://www.displaysearch.com/cps/rde/xchg/SID-0A424DE8-28DF6E59/displaysearch/hs.xsl/070108_16by9_PR.asp|title=Product Planners and Marketers Must Act Before 16:9 Panels Replace Mainstream 16:10 Notebook PC and Monitor LCD Panels, New DisplaySearch Topical Report Advises|publisher=DisplaySearch|date=2008-07-01|accessdate=2011-09-08}}</ref> By using the same aspect ratio for both TVs and monitors, manufacturing can be streamlined and research costs reduced by not requiring two separate sets of equipment, and since a 16:9 is narrower than a 16:10 panel of the same length, more panels can be created per sheet of glass. <ref>{{cite web|url=http://blog.lenovo.com/en/blog/display-ratio-change-again|title=Display Ratio Change (again)|date=2009-04-14|website=|url-status=live|accessdate=2020-01-22}}</ref> <ref>{{cite web|url=https://bit-tech.net/blogs/tech/16-10-vs-16-9-the-monitor-aspect-ratio/1/|title=16:10 vs 16:9 - the monitor aspect ratio conundrum|date=2012-10-22 |accessdate=2020-01-22}}</ref> <ref>{{cite web |url=https://press.trendforce.com/node/view/3307.html |title=Resurgence of 16:10 Aspect Ratio Laptop Computers to Occupy 2% Share of Non-Apple Market in 2020, Says TrendForce |date=2019-04-11 |accessdate=2020-01-22}}</ref> In 2011, Bennie Budler, product manager of IT products at Samsung South Africa, confirmed that monitors capable of 1920×1200 resolutions aren't being manufactured anymore.

[[Anamorphic widescreen|Anamorphic]] [[DVD]] transfers store the information as 5:4 (PAL) or 3:2 (NTSC) [[square pixels]], which is set to expand to either 16:9 or 4:3, which the television or video player handles. For example, a PAL DVD with a full frame image may contain a video resolution of 720×576 (5:4 ratio), but a [[Media player (software)|video player software]] will stretch this to 1024×576 square pixels with a 16:9 flag in order to recreate the correct aspect ratio. DVD producers can also choose to show even wider ratios such as 1.85:1 and 2.39:1<ref group="lower-alpha" name="anamorphic">The 2.39:1 ratio is commonly labeled 2.40:1, e.g., in the [[American Society of Cinematographers]]' ''American Cinematographer Manual'', and is mistakenly referred to as 2.35:1 (only cinema films before the 1970 [[Society of Motion Picture and Television Engineers|SMPTE]] revision used 2.35:1).</ref> within the 16:9 DVD frame by [[Hard matte|hard matting]] or adding black bars within the image itself. Some films which were made in a 1.85:1 aspect ratio, such as the U.S.-Italian co-production ''[[Man of La Mancha (film)|Man of La Mancha]]'' and [[Kenneth Branagh]]'s ''[[Much Ado About Nothing (1993 film)|Much Ado About Nothing]]'', fit quite comfortably onto a 1.7{{overline |7}}:1 HDTV screen and have been issued as an enhanced version on DVD without the black bars. Many [[digital video]] cameras have the capability to record in 16:9. [[16 mm film|Super 16 mm film]] is frequently used for television production due to its lower cost, lack of need for soundtrack space on the film itself, and aspect ratio similar to 16:9.{{citation needed|date=December 2010}} ==Common resolutions== Common resolutions for 16:9 are listed in the table below: <!-- NOTICE: This is a table of COMMON resolutions, not a table of "every possible 16:9 resolution the internet can think of".
