Mul\fiSync	PA	Series	Informa\fion
The  SpectraView  II  software  supports  the  MultiSync  PA231W,  PA241W,  PA271W  and  PA301W  monitors.  These 
models  feature  a  custom-designed  color  processor  called  the  SpectraView  Engine. This  sophisticated  processor, 
combined with internal luminance, temperature and time monitoring of the monitor, and individual characterization 
and calibration of each unit during production, results in an unparalleled level...

Glossary
Achromatic – Neutral in color (having no hue).

sities produces different colors. (See also Subtractive Primaries)
Backlight – the internal light source for a Liquid Crystal Display, such as fluorescent lamps or 
array of LEDs (Light Emitting Diodes).

Gamma – The relationship between the input video signal to a display monitor and the screen 
output luminance. Typically the screen luminance follows a mathematical power function of the 
input video signal, the exponent of which is called the gamma.
Gamut – The range of colors that can be reproduced on a particular device such as a monitor 
or printer, or that can be distinguished by a sensing device such as a scanner or the human 
eye.
Hue – The basic attribute of...

PAL – Phase Alternation by Line. A standard for encoding video signals used in Western Eu-
rope and parts of Asia.
Phosphors – Materials that emit light when struck by radiation of certain wavelengths.  CR T 
displays use phosphors that give off red, green, and blue light to display an image on the 
screen.
Profile – A file containing a description of the color characteristics of a device such as a moni-
tor, printer, or scanner.
Refresh Rate – The number of times...
