In this mode, the player has the capability to extract the 21:9 center portion of the movie content of a letterboxed disc, while re-arranging the 16:9 menus and subtitles for 21:9. The company Folded Space, also initiated by Panamorph, was working on a proprietary solution, MFE, to put anamorphic 21:9 video onto Blu-rays in a way compatible with standard players.Īdvanced Blu-ray players, like the Oppo BDP-203/205, can be put into a 21:9 output mode. Given that Blu-ray Discs include the letterboxing on the image, this effectively means widescreen movies will be shown in a 16:9 space, with black bars on top and bottom. Eventually, this feature was not included in the final specification. There was an effort, led by Panamorph, to add support for anamorphic video in a 21:9 aspect ratio to the Full HD, 3-D and Ultra HD Blu-ray specifications. In November 2016, CTA (formerly CEA) published CTA-861-G with these additional video timings in 64:27, as well as additional frame rates (48 Hz, 100/120 Hz UHD): 3840×2160p, anamorphic pixel aspect ratio of 4:3.1920×1080p, anamorphic pixel aspect ratio of 4:3.1680×720p, near-square pixel aspect ratio of 64:63.1280×720p, anamorphic pixel aspect ratio of 4:3.2.39:1), matching both with only a slight deviation.Īs of May 2013, video timings in this 64:27 aspect ratio are supported by the technical specification that defines video timings for the HDMI interface, CTA 861-F: 2.35:1) and the aspect ratio of modern anamorphic cinematic content (1024:429, approx. 2.370:1 is positioned between the classical CinemaScope aspect ratio (1678:715, approx. The "21:9" digital format's aspect ratio of approx. Note how the large center circle, representing the main image area, remains at a constant size on the 21:9 display, while it changes on the other two depending on the aspect ratio of the content. With the black bars being unnoticed, this has the effect of a changing image size when switching content aspect ratios.Ī 21:9 display allows to present all content up to 'Scope aspect ratios at equal height, with changing vertical bars to the left and right of the image. To avoid loss of content (due to cropping) or distortions (due to stretching), horizontal or vertical bars of a uniform color, usually black to make them less noticeable, are added to adjust the image. With content of different aspect ratios, adjustments have to be made when showing such content on a display with a fixed aspect ratio. The wider screen provides advantages in multitasking as well as a more immersive gaming experience, and even wider screens with aspect ratios such as 32:9 (allowing for two 16:9 views side-by-side) are available. It is also used in computer monitors, where the term "21:9" can represent aspect ratios of 43:18 and 12:5 in addition to 64:27. It is still prevalent in projection systems, using anamorphic lenses, and supported by a number of consumer electronics devices, including Blu-ray players and video scalers. Due to it causing pillarboxing with standard 16:9 content, and the resulting low consumer acceptance, this screen format has rarely been used since then. If it actually were 21:9 (2.3 3:1), the fraction could also be expressed in the reduced form as 7:3, relating to the 4:3 of standard-definition TVs.Ĭonsumer TVs with this aspect ratio were manufactured mainly from 2010 to 2017. Due to its common denominator, 21:9 is more relatable to 16:9, the aspect ratio of regular HDTVs, rather than the correct 64:27. The term "21:9" was chosen as a marketing term, first used by Philips in January 2009. This allows electronic scalers and optical anamorphic lenses to use an easily implementable 4:3 (1.3 3:1) scaling factor. The 64:27 aspect ratio of "21:9" is an extension of the existing video aspect ratios 4:3 (SDTV) and 16:9 (HDTV), as it is the third power of 4:3, where 16:9 of traditional HDTV is 4:3 squared. The main benefit of this screen aspect ratio is a constant display height when displaying other content with a lesser aspect ratio. 3:9), designed to show films recorded in CinemaScope and equivalent modern anamorphic formats. " 21:9" ("twenty-one by nine") is a consumer electronics (CE) marketing term to describe the ultrawide aspect ratio of 64:27 (2.
