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. The dot pitch of a computer display determines the absolute limit of possible pixel density.
A laser printer applies toner through a controlled electrostatic charge, and may be in the range of 600 to 2,400 DPI. The DPI measurement of a printer often needs to be considerably higher than the pixels per inch (PPI) measurement of a video display in order to produce similar-quality output. This is due to the limited range of colours for ...
When introducing the iPhone 4, Steve Jobs said the density of pixels needed for a Retina display is about 300 PPI (120 dot/cm) for a device held 10 to 12 inches (25 to 30 cm) from the eye. [1] This definition includes the distance from the screen to the observer (the viewing distance ), because moving the eye closer to the display makes it ...
The measure of how closely lines can be resolved in an image is called spatial resolution, and it depends on properties of the system creating the image, not just the pixel resolution in pixels per inch (ppi). For practical purposes the clarity of the image is decided by its spatial resolution, not the number of pixels in an image.
Typically, a resolution of 150 to 300 PPI works well for 4-color process printing. However, for printing technologies that perform color mixing through dithering rather than through overprinting (virtually all home/office inkjet and laser printers), printer DPI and image PPI have a very different meaning, and this can be misleading.
Saying that 300 DPI is the limit of vision is ridiculous nonsense, as it's a long-known fact that one can easily tell the difference between something printed at 300 DPI and 600 DPI. Common consumer printers now offer 1200 DPI and higher.
Blake Lively and Justin Baldoni aren't the first Hollywood actor-director duo to engage in on-set feuds. Will Smith and Chevy Chase infamously sparred with directors on their films.
In Microsoft Windows operating system specifically, the larger taskbar of Windows 7 occupies an additional 16-pixel lines by default, which may compromise the usability of programs that already demanded a full 1024 × 768 (instead of, e.g. 800 × 600) unless it is specifically set to use small icons; an "oddball" 784-line resolution would ...
