Multi-Color Graphics Array Introduced by IBM on ISA-based PS/2 models in 1987, with reduced cost compared to VGA. MCGA had a 320×200 256-colour (from a 262,144 colour palette) mode, and a 640×480 mode only in monochrome due to 64k video memory, compared to the 256k memory of VGA.

The 1280 × 1024 resolution became popular because at 24 bit/px color depth it fits well into 4 megabytes of video RAM. [citation needed] At the time, memory was extremely expensive. Using 1280 × 1024 at 24-bit color depth allowed using 3.75 MB of video RAM, fitting nicely with VRAM chip sizes which were available at the time (4 MB):
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 ...
An extended version of SMPTE Color Bars signal, developed by the Japanese Association of Radio Industries and Businesses as ARIB STD-B28 and standardized as SMPTE RP 219:2002 [15] (High-Definition, Standard-Definition Compatible Color Bar Signal) was introduced to test HDTV signal with an aspect ratio of 16:9 that can be down converted to a ...
Color depth, also known as bit depth, is either the number of bits used to indicate the color of a single pixel, or the number of bits used for each color component of a single pixel. When referring to a pixel, the concept can be defined as bits per pixel (bpp).
A 2-bit indexed color image. The color of each pixel is represented by a number; each number (the index) corresponds to a color in the color table (the palette).. In computing, indexed color is a technique to manage digital images' colors in a limited fashion, in order to save computer memory and file storage, while speeding up display refresh and file transfers.
Carbon disulfide (also spelled as carbon disulphide) is an inorganic compound with the chemical formula CS 2 and structure S=C=S.It is also considered as the anhydride of thiocarbonic acid. [8]
The compound 2-chlorobenzalmalononitrile (also called o-chlorobenzylidene malononitrile; chemical formula: C 10 H 5 ClN 2), a cyanocarbon, is the defining component of the lachrymatory agent commonly referred to as CS gas, a tear gas which is used as a riot control agent, and is banned for use in warfare due to the 1925 Geneva Protocol.
