  2. Display resolution standards - Wikipedia

    en.wikipedia.org/wiki/Display_resolution_standards

    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 ...

    The following is a comparison of high-definition smartphone displays, containing information about their specific screen technology, resolution, size and pixel density.It is divided into three categories, containing smartphones with 720p, 1080p and 1440p displays.

  4. 4K resolution - Wikipedia

    en.wikipedia.org/wiki/4K_resolution

    The first pixel-shifted 4K UHD projectors adopted by the market are Optoma, BenQ, Dell, et al., for those adopt a 2718×1528 pixel structure. The amount of data these projectors process is true 4K, but they overlap the pixels, which is what pixel shifting is. In fact, each of those pixels is far larger.

  5. List of common display resolutions - Wikipedia

    The resolution of 960H depends on whether the equipment is PAL or NTSC based: 960H represents 960 x 576 (PAL) or 960 x 480 (NTSC) pixels. [29] 960H represents an increase in pixels of some 30% over standard D1 resolution, which is 720 x 576 pixels (PAL), or 720 x 480 pixels (NTSC). The increased resolution over D1 comes as a result of a longer ...

    1080p progressive scan HDTV, which uses a 16:9 ratio. Some commentators also use display resolution to indicate a range of input formats that the display's input electronics will accept and often include formats greater than the screen's native grid size even though they have to be down-scaled to match the screen's parameters (e.g. accepting a 1920 × 1080 input on a display with a native 1366 ...

  7. Pixel density - Wikipedia

    en.wikipedia.org/wiki/Pixel_density

    The apparent PPI of a monitor depends upon the screen resolution (that is, the number of pixels) and the size of the screen in use; a monitor in 800×600 mode has a lower PPI than does the same monitor in a 1024×768 or 1280×960 mode.

  8. Image resolution - Wikipedia

    en.wikipedia.org/wiki/Image_resolution

    An image that is 2048 pixels in width and 1536 pixels in height has a total of 2048×1536 = 3,145,728 pixels or 3.1 megapixels. One could refer to it as 2048 by 1536 or a 3.1-megapixel image. The image would be a very low quality image (72ppi) if printed at about 28.5 inches wide, but a very good quality (300ppi) image if printed at about 7 ...

  9. Display aspect ratio - Wikipedia

    en.wikipedia.org/wiki/Display_aspect_ratio

    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.
