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.
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.

First, set all 4 to the color of the pixel we are currently scaling (as nearest-neighbor). Next look at the three pixels above, to the left, and diagonally above left: if all three are the same color as each other, set the top left pixel of our output square to that color in preference to the nearest-neighbor color.

The aspect ratio of an image is the ratio of its width to its height. It is expressed as two numbers separated by a colon, in the format width:height. Common aspect ratios are 1.85:1 and 2.39:1 in cinematography, 4:3 and 16:9 in television, and 3:2 in still photography
480p is the shorthand name for a family of video display resolutions.The p stands for progressive scan, i.e. non-interlaced.The 480 denotes a vertical resolution of 480 pixels, usually with a horizontal resolution of 640 pixels and 4:3 aspect ratio (480 × 4 ⁄ 3 = 640) or a horizontal resolution of 854 (848 should be used for mod16 compatibility) [1] pixels for an approximate 16:9 aspect ...
