Common aspect ratios used in film and display images. The common film aspect ratios used in cinemas are 1.85:1 and 2.39:1. [1] Two common videographic aspect ratios are 4:3 (1. 3:1), [a] the universal video format of the 20th century, and 16:9 (1. 7:1), universal for high-definition television and European digital television.
The extra pixels are used to form the increased area to the sides of the D1 image. The pixel density of 960H is identical to standard D1 resolution so it does not give any improvement in image quality, merely a wider aspect ratio. Alternative analog video transport technologies carrying higher resolutions than 960H include HD-TVI, HDCVI, and AHD.
The display aspect ratio (DAR) is the aspect ratio of a display device and so the proportional relationship between the physical width and the height of the display. It is expressed as two numbers separated by a colon ( x : y ), where x corresponds to the width and y to the height.
The aspect ratio determines how the image is scaled and stretched or cropped to fit the screen. The most common aspect ratios for graphics displays are 4:3, 16:10 (equal to 8:5), 16:9, and "21:9". The aspect ratio also affects the perceived size of objects on the screen. [5]

17:9 (≈1.889:1) display aspect ratio is also only approached: 8K Full Format (8192 × 4320) is the "base" of this line which is ≈1.896:1. (Old) edit summary: This is an update to Vector Video Standards4.svg to resize the file for newer and wider displays. I added resolutions UWHD (2560×1080), 4K and UHD-1.
The 64:27 aspect ratio is the logical extension of the existing video aspect ratios 4:3 and 16:9. It is the third power of 4:3, whereas 16:9 of widescreen HDTV is 4:3 squared. This allows electronic scalers and optical anamorphic lenses to use an easily implementable 4:3 (1.3 3 ) scaling factor.
