The increased resolution over D1 comes as a result of a longer horizontal scan. 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 ...
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 ...
The size of a screen is usually described by the length of its diagonal, which is the distance between opposite corners, typically measured in inches. It is also sometimes called the physical image size to distinguish it from the "logical image size," which describes a screen's display resolution and is measured in pixels. [1] [2]
The unusual 5:4 aspect ratio makes the display slightly different from QQVGA dimensions. 160×128 (20k) 160 128 20,480 5:4 UNNAMED UNNAMED 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.
For perspective, such a device at 15 inch (38 cm) screen size would have to display more than four Full HD screens (or WQUXGA resolution). The PPI pixel density specification of a display is also useful for calibrating a monitor with a printer. Software can use the PPI measurement to display a document at "actual size" on the screen.
The resolution 3840 × 2160, sometimes referred to as 4K UHD or 4K × 2K, has a 16:9 aspect ratio and 8,294,400 pixels. It is double the size of Full HD (1920 × 1080) in both dimensions for a total of four times as many pixels, and triple the size of HD (1280 × 720) in both dimensions for a total of nine times as many pixels. It is the lowest ...
Below is a list of currently available tablet PCs grouped by their width, depth, height, screen size, and appropriate tablet case sizes. The most popular presently available tablet computers are compared in the following table:
The display aspect ratio (DAR) is calculated from the physical width and height of a display, measured each in inch or cm (Display size). The pixel aspect ratio (PAR) is calculated from the width and height of one pixel. The storage aspect ratio (SAR) is calculated from the numbers of pixels in width and height stated in the display resolution.
