Widescreen images are a variety of aspect ratios used in film, television and computer screens. In film, a widescreen film is any film image with a width-to-height aspect ratio greater than the standard 1.37:1 Academy aspect ratio provided by 35mm film.
For television, the original screen ratio for broadcasts was 4:3 (1.33:1). In the 2000s, 16:9 (1.78:1) TV displays came into wide use. They are typically used in conjunction with high-definition television (HDTV) receivers, or Standard-Definition (SD) DVD players and other digital television sources.
With computer displays, aspect ratios wider than 4:3 are also called widescreen. Widescreen computer displays were previously typically of 16:10 aspect ratio, now they are shifting to 16:9.
Widescreen was first used in the film of The Corbett-Fitzsimmons Fight in 1897. This was not only the longest film that had been released to date at 100 minutes, it was also the first widescreen film being shot on 63 mm Eastman stock with 5 perforations per frame.
Widescreen was first widely used in the late 1920s in some short films and newsreels, including Abel Gance's film Napoleon (1927) with a final widescreen sequence in what Gance called Polyvision. Claude Autant-Lara released a film Pour construire un feu (To Build a Fire, 1928) in the early Henri Chretien widescreen process, later adapted by Twentieth Century-Fox for CinemaScope in 1952.
On May 26, 1929, Fox Film Corporation released Fox Grandeur News and Fox Movietone Follies of 1929 in New York City in the Fox Grandeur process. Other films shot in widescreen were the musical Happy Days (1929) which premiered at the Roxy Theater, New York City, on February 13, 1930, starring Janet Gaynor and Charles Farrell and a 12 year old Betty Grable as a chorus girl; Song o’ My Heart, a musical feature starring Irish tenor John McCormack and directed by Frank Borzage (Seventh Heaven, A Farewell to Arms), which was shipped from the labs on March 17, 1930, but never released and may no longer survive, according to film historian Miles Kreuger (the 35mm version, however, debuted in New York on March 11, 1930); and the western The Big Trail (1930) starring John Wayne and Tyrone Power, Sr. which premiered at Grauman's Chinese Theatre in Hollywood on October 2, 1930, all of which were also made in the 70mm Fox Grandeur process.
RKO Radio Pictures released Danger Lights with Jean Arthur, Louis Wolheim, and Robert Armstrong on August 21, 1930 in a 65mm widescreen process known as NaturalVision, invented by film pioneer George K. Spoor. On November 13, 1930, United Artists released The Bat Whispers directed by Roland West in a 70mm widescreen process known as Magnafilm. Warner Brothers released Song of the Flame and Kismet (both 1930) in a widescreen process they called Vitascope.
In 1930, after experimenting with the system called Fanthom Screen for The Trail of '98 (1928), MGM came out with a system called Realife. MGM filmed The Great Meadow (1930) in Realife—however, it's unclear if it was ever released in that widescreen process due to declining interest of the movie-going public.
By 1932, the Great Depression had forced studios to cut back on needless expense and it was not until 1953 that wider aspect ratios were again used in an attempt to stop the fall in attendance due, partially, to the emergence of television in the U.S. However, a few producers and directors, among them Alfred Hitchcock, have been reluctant to use the anamorphic widescreen size featured in such formats as Cinemascope. Hitchcock alternatively used VistaVision, a non-anamorphic widescreen process developed by Paramount Pictures and Technicolor which could be adjusted to present various flat aspect ratios.
Masked (or flat) widescreen was introduced in April 1953. The negative is shot exposing the Academy ratio using spherical lenses, but the top and bottom of the picture are hidden or masked off by a metal aperture plate, cut to specifications of the theater's screen, in the projector. Alternatively, a hard matte in the printing or shooting stages may be used to mask off those areas while filming for composition purposes, but an aperture plate is still used to block off the appropriate areas in the theater. A detriment is that the film grain size is thus increased because only part of the image is being expanded to full height. Films are designed to be shown in cinemas in masked widescreen format but the full unmasked frame is sometimes used for television. In such an instance, a photographer will compose for widescreen, but "protect" the full image from things such as microphones and other filming equipment. Standardized "flat" ratios are 1.66:1, 1.75:1, 1.85:1, and 2:1. 1.85:1 has become the predominant aspect ratio for the format.
35 mm Anamorphic This type of widescreen is used for Cinemascope, Panavision, and several other "copycat" processes. The film is essentially shot "squeezed", so that the actors appear vertically elongated on the actual film. A special lens inside the projector unsqueezes the image so that it will appear normal. Films shot in Cinemascope or Panavision are usually projected at a 2.39:1 aspect ratio, though sometimes the ratio can be as high as 2.55:1.
Super gauges The full negative frame, including the area traditionally reserved for the sound track, is filmed using a wider gate. The print is then shrunk and/or cropped in order to fit it back onto release prints. The aspect ratio for Super 35, for example, can be set to virtually any projection standard.
Large gauge A 70 mm film frame is not only twice as wide as a standard frame but also has greater height. Shooting and projecting a film in 70 mm therefore gives more than four times the image area of non-anamorphic 35 mm film with no loss of quality. Few major dramatic narrative films have been filmed entirely on this format since the 1970s; the three most recent are Ron Howard's Far and Away, Kenneth Branagh's Hamlet, and Paul Thomas Anderson's The Master. For many years, large budget pictures shot anamorphically used reserve stocks of 70mm film for SFX shots involving CGI or blue-screen compositing as the anamorphic format creates problems with said effects. It has also been used to sometimes strike 70 mm blow-up prints for "roadshow" tours in select cities from the 35 mm camera negative in order to capitalize on the extra sound channels provided. The introduction of digital sound systems and diminishing number of installed 70 mm projectors has made a 70 mm release largely obsolete. However, blowups from 35 mm formats to IMAX has recently become popular for a limited number of blockbuster films.
Paramount's VistaVision was a larger gauge precursor to 70 mm film. Introduced in 1954, it ran standard 35 mm film through the camera horizontally to achieve a widescreen effect using greater negative area, in order to create a finer-grained four-perforation 35 mm prints in an era where standard monopack stock could not produce finer results. Negative frames were eight perforations wide. Eight-perf photography is sometimes used for shooting special effects in order to produce a finer grained matte that can be used in optical printing without image degradation, and is notable for its use in Lucasfilm's original three Star Wars films, among others. Another similar system with horizontal orientation was MGM's Arnoldscope.
Multiple cameras/projectors The Cinerama system originally involved shooting with three synchronized cameras locked together side by side, and projecting the three resulting films on a curved screen with three synchronized projectors, resuting in an ultra wide aspect ratio of 2.89. Later Cinerama movies were shot in 70 mm anamorphic (see below), and the resultant widescreen image was divided into three by optical printers to produce the final threefold prints.
The technical drawbacks of Cinerama are discussed in its own article. Only two narrative feature films, The Wonderful World of the Brothers Grimm and How the West Was Won, were filmed in three-camera Cinerama, and several sequences from the latter were actually filmed in Ultra-Panavision. With the exception of a few films created sporadically for use in specialty Cinerama theaters, the format is essentially dead.
A non-Cinerama, three-projector process was famously pioneered for the final reel of Abel Gance's epic film Napoléon (1927) The process, called Polyvision by Gance, consisted of three 1.33 images side by side, so that the total aspect ratio of the image is 4:1. The technical difficulties in mounting a full screening of the film, however, make most theaters unwilling or unable to show it in this format.
Between 1956 and 1957 the Soviets developed Kinopanorama, which is identical in most respects to the original three-camera Cinerama.
Anamorphic 70 mm. 70 mm with anamorphic lenses, popularly known as "Ultra Panavision" or "MGM Camera 65", creates an even wider high-quality picture. This camera process was most famously used in the 1959 version of "Ben-Hur", resulting in an aspect ratio of 2.76:1, one of the widest projected images ever used for a feature film. 70 mm anamorphic was not commonly used, due to the very high production costs, although it was favored for epic films such as Ben-Hur in order to capture wide panoramic landscapes and high-budget scenes with thousands of extras and enormous sets. This system is obsolete, despite its ease in setting up.
The original screen ratio for television broadcasts was 4:3 (1.33:1). When preparing a film that was originally intended to be displayed in widescreen for television broadcast the material was often edited with the sides truncated, using a technique called pan and scan. Sometimes, in the case of Super35, the full film negative was shown unmasked on TV (i.e., with the hard matte removed), however this causes the 4:3 image not to be what the director intended the audience to see—and sometimes boom mikes, edited out of the shot when the picture is matted, can be visible. Modern widescreen televisions feature a 16:9 (and occasionally 16:10) aspect ratio, allowing them to display a 16:9 widescreen picture without letterboxing (or with a minimal letterbox in the case of 16:10).
In Europe the PAL TV format, with its higher resolution than NTSC format meant the quality issues of letterboxed or matted movies on TV was not as severe. There is also an extension to PAL, called PALplus, which allows specially equipped receivers to receive a PAL picture as true 16:9 with a full 576 lines of vertical resolution, provided the station employs the same system. Standard PAL receivers will receive such a broadcast as a 16:9 image letterboxed to 4:3, with a small amount of color noise in the black bars; this "noise" is actually the additional lines which are hidden inside the color signal. This system has no equivalent in analog NTSC broadcasting.
Despite the existence of PALplus and support for widescreen in the DVB-based digital satellite, terrestrial and cable broadcasts in use across Europe, only Belgium, Ireland, the Netherlands, Austria, Germany, Scandinavia and the UK have adopted widescreen on a large scale, with over half of all widescreen channels available by satellite in Europe targeting those areas. The UK, in particular, began moving to widescreen with the advent of digital terrestrial television in the late 1990s, and commercials were required to be delivered to broadcasters in widescreen as of 1 July 2000, "C-Day".
Widescreen televisions are typically used in conjunction with Digital, High-Definition Television (HDTV) receivers, or Standard-Definition (SD) DVD players and other digital television sources. Digital material is provided to widescreen TVs either in high-definition format, which is natively 16:9 (1.78:1), or as an anamorphically-compressed standard-definition picture. Typically, devices decoding Digital Standard-Definition pictures can be programmed to provide anamorphic widescreen formatting, for 16:9 sets, and formatting for 4:3 sets. Pan-and-scan mode can be used on 4:3 if the producers of the material have included the necessary panning data; if this data is absent, letterboxing or centre cut-out is used.
HD DVD and Blu-ray disc players were introduced in 2006. Toshiba ceased production of HD DVD players in early 2008. Consumer camcorders are also available in the HD-video format at fairly low prices. These developments will result in more options for viewing widescreen images on television monitors.
Computer displays 
Computer displays with aspect ratios wider than 4:3 are also called widescreen. Widescreen computer displays are typically of the 16:9 or 16:10 aspect ratio. Widescreen (16:9) monitors can be found in resolutions of 1024×576, 1152×648, 1280×720, 1366×768, 1600×900, 1920×1080, 2560×1440 and 3840×2160. Apple's 27" iMac introduced the 16:9 resolution: 2560×1440 in late 2009. Widescreen monitors are since 2008 the mainstream standard for computer displays.
Transition to widescreen 
Until about 2003, most computer monitors had a 4:3 aspect ratio and some had 5:4. Between 2003 and 2006, monitors with 16:9 and mostly 16:10 (8:5) aspect ratios became commonly available, first in laptops and later also in standalone monitors. Reasons for this transition is alleged to be the productive uses for such monitors, i.e. besides widescreen movie viewing and computer game play, are the word processor display of two standard letter pages side by side, as well as CAD displays of large-size drawings and CAD application menus at the same time. In 2008, 16:10 became the most common sold aspect ratio for LCD monitors and the same year 16:10 was the mainstream standard for laptops and notebooks.
- Innovative product concepts drives a new product cycle and stimulating the growth of the notebook PC and LCD monitor market.
- 16:9 provides better economic cut (panelization) in existing TFT LCD fabs.
- 16:9 products provide wider aspect ratio.
- The widespread adoption of High Definition in the consumer entertainment sector will help end users readily adopt the new products with the wider aspect ratio.
- The 16:9 panels provide an opportunity for PC brands to further diversify their products.
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. “It is all about reducing manufacturing costs. The new 16:9 aspect ratio panels are more cost effective to manufacture locally than the previous 16:10 panels”
In 2011, Non-widescreen displays with 4:3 aspect ratios still were being manufactured, but in small quantities. The reasons for this was according to Samsung that the “Demand for the old 'Square monitors' has decreased rapidly over the last couple of years,” and “I predict that by the end of 2011, production on all 4:3 or similar panels will be halted due to a lack of demand.”
Suitability for applications
- Since many modern DVDs and some TV shows are in a widescreen format, widescreen displays are optimal for their playback on a computer. 16:9 material on a 16:10 display will be letterboxed. In data processing or viewing 4:3 entertainment material such as older films and digital photographs, the widescreen will be letterboxed.
- In the majority of games since 2005, you get wider field of view with a widescreen monitor.
- Games prior to 2005 usually work better with a 4:3 than a widescreen monitor because of better compatibility.
When monitors are sold, the quoted size is the diagonal measurement of the display area. Because of the different ratio, a 16:9 monitor will have a shorter height than a 4:3 monitor of the same advertised size.
Since computer displays are advertised by their diagonal measure, for monitors with the same display area, a wide screen monitor will have a larger diagonal measure, thus sounding more impressive (However for monitors with the same diagonal measure, a wide screen monitor will have smaller display area). Within limits, the amount of information that can be displayed, and the cost of the monitor depend more on area than on diagonal measure.
Some monitors can be rotated to facilitate tasks that are more limited by the height of the monitor (such as word processing).
