The dot pitch of a computer display determines the absolute limit of possible pixel density. Typical circa-2000 cathode-ray tube or LCD computer displays range from 67 to 130 PPI, though desktop monitors have exceeded 200 PPI, and certain smartphone manufacturers' flagship mobile device models have been exceeding 500 PPI since 2014.
The single fixed-screen mode used in first-generation (128k and 512k) Apple Mac computers, launched in 1984, with a monochrome 9" CRT integrated into the body of the computer. Used to display one of the first mass-market full-time GUIs, and one of the earliest non-interlaced default displays with more than 256 lines of vertical resolution.
The Parallel Peripheral Interface (PPI) is a peripheral found on the Blackfin embedded processor. The PPI is a half-duplex , bi-directional port that is designed to connect directly to LCDs , CMOS sensors , CCDs , video encoders (video DACs ), video decoders (video ADCs ) or any generic high speed, parallel device.

Contrast DIMM. solid-state drive
The pixel density of 150 ppi was the lowest of any eink Kindle device. It supports displaying PDF files. It was marketed as more suitable for displaying newspaper and textbook content, [ 14 ] includes built-in speakers, and has an accelerometer that enables users to rotate pages between landscape and portrait orientations when the Kindle DX is ...
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.
General-purpose computing on graphics processing units (GPGPU, or less often GPGP) is the use of a graphics processing unit (GPU), which typically handles computation only for computer graphics, to perform computation in applications traditionally handled by the central processing unit (CPU).
These keys can be selected using the mouse or another pointing device, or a single key or small group of keys can be used to cycle through the keys on the screen. The on-screen keyboard is the most common type of virtual keyboard. The accuracy of this keyboard depends only on hitting the right key.
