The new 16:9 aspect ratio panels are more cost-effective to manufacture locally than the previous 16:10 panels'. 'It is all about reducing manufacturing costs. In 2011, Bennie Budler, product manager of IT products at Samsung South Africa, confirmed that monitors capable of 1920 × 1200 resolutions are not being manufactured anymore. 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.

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'. Over a long period in the late 2000s and early 2010s, the computer industry switched from 4:3 to 16:9 as the most common aspect ratio for monitors and laptops. The Community fund for the 16:9 Action Plan amounted to €228,000,000. In 1993, the European Union instituted the 16:9 Action Plan, to accelerate the development of the advanced television services in 16:9 aspect ratio, both in PALplus (compatible with regular PAL broadcasts) and also in HD-MAC (an early HD format). This has similarities to a filming technique called open matte. Content creators frame critical content or graphics to fit within the 1.33:1 raster space. 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. Most 4:3 (1.3 3:1) and 2.40:1 video is now recorded using a ' shoot and protect' technique that keeps the main action within a 16:9 (1.7 7:1) inner rectangle to facilitate HD broadcast. While 16:9 (1.7 7:1) was initially selected as a compromise format, the subsequent popularity of HDTV broadcast has solidified 16:9 as perhaps the most common video aspect ratio in use. Applying the same geometric mean technique to 16:9 and 4:3 yields an aspect ratio of around 1.5396:1, sometimes approximated as 14:9 (1.5 5:1), which is likewise used as a compromise between these ratios. The value found by Powers is exactly the geometric mean of the extreme aspect ratios, 4:3 and 2.35:1, 47 15 ≈ 1.77 which is coincidentally close to 16:9. 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 1.7 7:1 and all of them also covered a smaller common inner rectangle with the same aspect ratio 1.77:1. Powers cut out rectangles with equal areas, shaped to match each of the popular aspect ratios.

The popular choices in 1980 were 4:3 (based on TV standard's ratio at the time), 15:9 (the European 'flat' 1.6 6:1 ratio), 1.85:1 (the American 'flat' ratio) and 2.35:1 (the CinemaScope/ Panavision) ratio for anamorphic widescreen. Powers, a member of the SMPTE Working Group on High-Definition Electronic Production, first proposed the 16:9 (1.7 7:1) aspect ratio in 1984, when nobody was creating 16:9 videos. The calculation considers the extreme rectangles, where m and n are multipliers to maintain their respective aspect ratios and areas.ĭr. DVD producers can also choose to show even wider ratios such as 1.85:1 and 2.40:1 within the 16:9 DVD frame by hard matting or adding black bars within the image itself.ĭerivation of the 16:9 aspect ratioThe 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. Many digital video cameras have the capability to record in 16:9, and 16:9 is the only widescreen aspect ratio natively supported by the DVD standard.

Japan's Hi-Vision originally started with a 5:3 (1.6 6:1) ratio but converted when the international standards group introduced a wider ratio of 16 to 9. It has replaced the 'fullscreen' 4:3 aspect ratio.ġ6:9 (1.7 7:1) (said as sixteen by nine or sixteen to nine) is the international standard format of HDTV, non-HD digital television and analog widescreen television systems PALplus and Wide-aspect Clear-vision.

Once seen as exotic, since 2009, it has become the most common aspect ratio for televisions and computer monitors, and is also the international standard image format for UHD, HDTV, Full HD and SD digital television. An LCD television set with a 16:9 image ratio.ġ6:9 (1.7 7:1) is a widescreen aspect ratio with a width of 16 units and height of 9.
