Glossary
D
D-SUB
A VGA Analog input connector. Your monitor comes with a D-Sub cable.
Digital Visual Interface (DVI)
The Digital Visual Interface (DVI) specification provides a high-speed digital connection for visual
data types that is display technology independent. The interface is primarily focused at providing a
connection between a computer and its display device. The DVI specification meets the needs of all
segments of the PC industry (workstation, desktop, laptop, etc.) and will enable these different
segments to unite around one monitor interface specification.
The DVI interface enables:
1. Reduce signal loss and video noise in signal due to less signal conversion.
2. Independent from display technology, and can be used on LCD, Plasma, LCOS, etc.
3.
Plug and play through hot plug detection, EDID and DDC2B.
4. Digital and Analog support in a single connector (DVI-I only).
G
Gamma
Screen luminance as a function of video voltage approximately follows a mathematical power
function of the input video signal, the exponent of which is called gamma.
Grayscale
An achromatic scale ranging from black through a series of successively lighter grays to white.
Such a series may be made up of steps, which appear to be equally distant from one another. If the
Analog/ Digital converter is 8 bit, then the monitor can display at most 2
monitor, R.G.B. each color hads 256 levels. Thus, total color can display is 256x256x256= 16.7
million.
