Pixel aspect ratio 1:1 Pixel aspect ratio 2:1. A Pixel aspect ratio (often abbreviated PAR) is a mathematical ratio that describes how the width of a pixel in a digital image compared to the height of that pixel. Most digital imaging systems display an image as a grid of tiny, square pixels.
These may also use other aspect ratios by cropping otherwise black bars at the top and bottom which result from cinema aspect ratios greater than 16∶9, such as 1.85 or 2.35 through 2.40 (dubbed "Cinemascope", "21∶9" etc.), while the standard horizontal resolution, e.g. 1920 pixels, is usually kept.
Hence, the actual pixel aspect ratio PAR for PAL video is a little different from that given by the formula, specifically 12:11 for PAL and 10:11 for NTSC. For consistency, the same effective pixel aspect ratios are used even for standard definition digital video originated in digital form rather than converted from analog.
Its square-pixel aspect ratio is 15:9 (or 5:3), in contrast to HDTV's 16:9 and 1280 × 800 's 16:10. It is also the lowest resolution that might be found in an "Ultrabook" standard laptop, as it satisfies the minimum horizontal and vertical pixel resolutions required to officially qualify for the designation.

CinemaScope was developed to use a separate film for sound (see Audio below), thus enabling the full silent 1.33:1 aperture to be available for the picture, with a 2:1 anamorphic squeeze applied that would allow an aspect ratio of 2.66:1. When, however, developers found that magnetic stripes could be added to the film to produce a composite ...
The nearly-square (but landscape) aspect ratio and coarse pixel resolution gave these games a characteristic visual style. Colour depth ranged from 4 colours (2 bpp ) with the original Game Boy , through 16–32 colours (4–5 bpp) with the Game Gear , to a maximum of 56 colours (equivalent of 6 bpp) from a wider palette with the Game Boy Color .
Negative aspect ratio is the image ratio determined by the ratio of the gate dimensions multiplied by the anamorphic power of the camera lenses (1× in the case of spherical lenses). [1] Gate dimensions are the width and height of the camera gate aperture, and by extension the film negative frame.
1080p progressive scan HDTV, which uses a 16:9 ratio. Some commentators also use display resolution to indicate a range of input formats that the display's input electronics will accept and often include formats greater than the screen's native grid size even though they have to be down-scaled to match the screen's parameters (e.g. accepting a 1920 × 1080 input on a display with a native 1366 ...
