16:9 is a widescreen aspect ratio with a width of 16 units and height of 9 units. Once seen as an "exotic" aspect ratio, [ 1 ] since 2009, it has become the most common aspect ratio for televisions and computer monitors , and is also the universal standard image format for the universal 1080p , 2160p and 4320p formats.
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.
A viewer watching on a standard 4:3 (non-widescreen) television would see a 4:3 image of the commercial with 2 sets of black stripes, vertical and horizontal (windowboxing or the postage stamp effect). A similar scenario may also occur for a widescreen set owner when viewing 16:9 material embedded in a 4:3 frame, and then watching that in 16:9.
The ratio of the width to the height of an image is known as the aspect ratio, or more precisely the display aspect ratio (DAR) – the aspect ratio of the image as displayed; for TV, DAR was traditionally 4:3 (a.k.a. fullscreen), with 16:9 (a.k.a. widescreen) now the standard for HDTV.
The aspect ratio also affects the perceived size of objects on the screen. [5] The native screen resolution together with the physical dimensions of the graphics display can be used to calculate its pixel density. An increase in the pixel density often correlates with a decrease in the size of individual pixels on a display.
The first popular widescreen ratio for computer displays was 16:10, and 16:9 has been the most common ratio since 2012. 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 .

A shared size for older portable video game systems. 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 ...
