This mode was mainly used to display 64 × 24 or 85 × 24 columns text screen, and originally only Timex Sinclair computers (where its named Hi-Res) and some Russian clones [62] can display it. It also takes 12 KB RAM. In the case of the Timex, this mode is activated through the command OUT 255,1.
Display Data Channel (DDC) is a collection of protocols for digital communication between a computer display and a graphics adapter that enable the display to communicate its supported display modes to the adapter and that enable the computer host to adjust monitor parameters, such as brightness and contrast.
Multi-monitor, also called multi-display and multi-head, is the use of multiple physical display devices, such as monitors, televisions, and projectors, in order to increase the area available for computer programs running on a single computer system. Research studies show that, depending on the type of work, multi-head may increase the ...

This is the highest resolution that generally can be displayed on analog computer monitors (most CRTs), and the highest resolution that most analogue video cards and other display transmission hardware (cables, switch boxes, signal boosters) are rated for (at 60 Hz refresh). 24-bit colour requires 9 MB of video memory (and transmission ...
LCD monitors are fixed-pixel displays, where the number of rows and columns displayed on the screen are constant, set by the construction of the panel. When the input signal has a resolution that does not match the number of pixels in the display, the LCD controller must still populate the same number of image elements.
Became a nearly ubiquitous analog computer display connector after first being introduced with IBM x86 machines. Older VGA connectors were DE-9 (9-pin). The modern DE-15 connector can carry Display Data Channel to allow the monitor to communicate with the graphics card, and optionally vice versa. [1] Being replaced by DVI from 1999 onward. DB13W3
Initially intended for use by computer monitors and video cards, the standard made its way into consumer televisions. The parameters defined by standard include horizontal blanking and vertical blanking intervals, horizontal frequency and vertical frequency (collectively, pixel clock rate or video signal bandwidth), and horizontal/vertical sync ...
