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 HD or 720p resolution of 1280 × 720 pixels stems from high-definition television (HDTV), where it originally used 50 or 60 frames per second. With its 16:9 aspect ratio, it is exactly 2 times the width and 1 + 1 / 2 times the height of 4:3 VGA ( 640 × 480 ), which shares its aspect ratio and 480 line count with NTSC .
The term display resolution is usually used to mean pixel dimensions, the maximum number of pixels in each dimension (e.g. 1920 × 1080), which does not tell anything about the pixel density of the display on which the image is actually formed: resolution properly refers to the pixel density, the number of pixels per unit distance or area, not ...
4:3 (non-square pixels) 1–4 bpp typical, 2 or 3 bpp common. WQVGA: Wide Quarter Video Graphics Array Effectively 1/16 the total resolution (1/4 in each dimension) of "Full HD", but with the height aligned to an 8-pixel "macroblock" boundary. Common in small-screen video applications, including portable DVD players and the Sony PSP. 480×272 ...
Image resolution is the level of detail of an image. The term applies to digital images, film images, and other types of images. "Higher resolution" means more image detail. Image resolution can be measured in various ways. Resolution quantifies how close lines can be to each other and still be visibly resolved. Resolution units can be tied to ...
The color images appear similar. The lower row shows the resolution of the color information. Many consumer electronics such as mobile phones store video footage in Y′C B C R format with 4:2:0 chroma subsampling, which records color information at only one quarter the resolution as the brightness information.

Fixed pixel displays are display technologies such as LCD and plasma that use an unfluctuating matrix of pixels with a set number of pixels in each row and column. [1] [2] With such displays, adjusting to different aspect ratios because of different input signals requires complex processing. [2] [better source needed]
Scalable Vector Graphics are well suited to simple geometric images, while photographs do not fare well with vectorization due to their complexity. Note that the special characteristics of vectors allow for greater resolution example images. The other algorithms are standardized to a resolution of 160x160 and 218x80 pixels respectively.
