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.
The difference is that whilst D1 has a 4:3 aspect ratio 960H has a 16:9 widescreen aspect ratio. 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.
The aspect ratio of the pixels themselves is known as the pixel aspect ratio (PAR) – for square pixels this is 1:1 – and these are related by the identity: SAR × PAR = DAR Rearranging (solving for PAR) yields:
The pixel aspect ratio (PAR) is calculated from the width and height of one pixel. The storage aspect ratio ... A 1:1 aspect ratio results in a square display.
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.

This is known as the aspect ratio. A screen's physical aspect ratio and the individual pixels' aspect ratio may not necessarily be the same. An array of 1280 × 720 on a 16:9 display has square pixels, but an array of 1024 × 768 on a 16:9 display has oblong pixels.
Aspect ratio: Although most modern phones can snap 1:1 (square) or 16:9 (wide) photos, the default setting tends to be 4:3. Some frames, however, have 16:9 screens, meaning you'll end up with ...
This is generally the native resolution—with, therefore, square pixels—of standard 17" and 19" LCD monitors. It was often a recommended resolution for 17" and 19" CRTs also, though as they were usually produced in a 4:3 aspect ratio, it either gave non-square pixels or required adjustment to show small vertical borders at each side of the ...
