Display resolution standards. A display resolution standard is a commonly used width and height dimension (display resolution) of an electronic visual display device, measured in pixels. This information is used for electronic devices such as a computer monitor. Certain combinations of width and height are standardized (e.g. by VESA [ 1][ 2 ...
For a pixel pair (one white and one black pixel) this gives a pixel density of 128 pixels per degree (PPD). 6/6 vision is defined as the ability to resolve two points of light separated by a visual angle of one minute of arc, corresponding to 60 PPD, or about 290–350 pixels per inch for a display on a device held 250 to 300 mm from the eye.
The aspect ratio of an image is the ratio of its width to its height. It is expressed as two numbers separated by a colon, width:height. Common aspect ratios are 1.85:1 and 2.40:1 in cinematography, 4:3 and 16:9 in television, and 3:2 in still photography .
HDMI is a digital replacement for analog videostandards. DVI-D, VGAand HDMI connectors on a graphics card. HDMI implements the ANSI/CTA-861standard, which defines video formats and waveforms, transport of compressed and uncompressed LPCMaudio, auxiliary data, and implementations of the VESA EDID.

The Pixel 5, which costs $100 more than that, supports both sub-6Ghz and mmwave systems, so you might as well get Google’s most expensive phone since it brings water resistance, a faster screen ...
4K resolution refers to a horizontal display resolution of approximately 4,000 pixels. [ 1] Digital television and digital cinematography commonly use several different 4K resolutions. In television and consumer media, 3840 × 2160 ( 4K UHD) with a 16:9 aspect ratio is the dominant 4K standard, whereas the movie projection industry uses 4096 × ...
The nanometre ( SI symbol: nm) is a unit of length in the metric system equal to 10−9 metres ( 1 1 000 000 000 m = 0.000 000 001 m ). To help compare different orders of magnitude, this section lists lengths between 10 −9 and 10 −8 m (1 nm and 10 nm). 1 nm – diameter of a carbon nanotube.
For example, the GSD of Landsat is ≈30m, which means the smallest unit that maps to a single pixel within an image is ≈30m x 30m. The latest commercial satellite (GeoEye 1) has a GSD of 0.41 m. This compares to a 0.3 m resolution obtained by some early military film based reconnaissance satellites such as Corona. [citation needed]
