In most computer display systems, images are encoded with a gamma of about 0.45 and decoded with the reciprocal gamma of 2.2. A notable exception, until the release of Mac OS X 10.6 (Snow Leopard) in September 2009, were Macintosh computers, which encoded with a gamma of 0.55 and decoded with a gamma of 1.8.
The "luminance contrast" is the ratio between the higher luminance, L H, and the lower luminance, L L, that define the feature to be detected.This ratio, often called contrast ratio, CR, (actually being a luminance ratio), is often used for high luminances and for specification of the contrast of electronic visual display devices.
An LCD technology is dynamic contrast (DC), also called advanced contrast ratio (ACR), and smart contrast ratio (SCR [4]) and various other designations.When there is a need to display a dark image, a display that supports dynamic contrast underpowers the backlight lamp (or decreases the aperture of the projector's lens using an iris), but proportionately amplifies the transmission through the ...
Note the DE-9 connector, cryptic mode switch, contrast and brightness controls at front, and the V-Size and V-Hold knobs at rear, which allow the control of the scaling and signal to CRT refresh rate synchronization respectively. Various computer display standards or display modes have been used in the history of the personal computer.

For example, in the case of graphical computer displays, contrast depends on the properties of the picture source or file and the properties of the computer display, including its variable settings. For some screens the angle between the screen surface and the observer's line of sight is also important.
