Extended Display Identification Data (EDID) and Enhanced EDID (E-EDID) are metadata formats for display devices to describe their capabilities to a video source (e.g., graphics card or set-top box). The data format is defined by a standard published by the Video Electronics Standards Association (VESA).
Color 6 is treated specially; normally, color 6 would become dark yellow, as seen to the left, but in order to achieve a more pleasing brown tone, special circuitry in most RGBI monitors, starting with the IBM 5153 color display, [11] makes an exception for color 6 and changes its hue from dark yellow to brown by reducing the analogue green ...
These mappings allow a choice between closest possible color matching, and remapping the entire color range to allow for different gamuts. The reference illuminant of the Profile connection space (PCS) is a 16-bit fractional approximation of D50 ; [ 4 ] its white point is XYZ=(0.9642, 1.000, 0.8249).
DPMS is a hardware standard that allows graphics cards to communicate with DPMS-compliant monitors via a special signalling system that can be used with existing graphics controllers and monitor cables. This signalling system allows the graphics card to tell the monitor to go into a number of different power management or power saving states ...
A BIOS Color Attribute is an 8 bit value where the low 4 bits represent the character color and the high 4 bits represent the background color. The name comes from the fact that these colors are used in BIOS interrupts, specifically INT 10h, the video interrupt. When writing text to the screen, a BIOS color attribute is used to designate the ...
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.
Much the way the system BIOS provides a set of functions that are used by software programs to access the system hardware, the video BIOS provides a set of video-related functions that are used by programs to access the video hardware as well as storing vendor-specific settings such as card name, clock frequencies, VRAM types & voltages.
Color management is the process of ensuring consistent and accurate colors across various devices, such as monitors, printers, and cameras.It involves the use of color profiles, which are standardized descriptions of how colors should be displayed or reproduced.
