Backlight; Back light
Backlights illuminate the LCD monitors from the side or back, so that the images on the displays
can be readable in poor lighting conditions.
Color Temperature
Color temperature is the temperature at which a black body radiates a given spectrum of color. It
is measured in degrees Kelvin (K). The higher the color temperature, the closer the color is to blue,
and the lower the color temperature, the closer to red.
DDC/CI
DDC/CI, short for Display Data Channel/Command Interface, which was developed by Video
Electronics Standards Association (VESA) to expand on the existing DDC standard. A monitor
utilizes DDC/CI can make bi-directional communication between PC and itself, without an
additional cable connection. The video graphics card and the standard analog or DVI signal cable
will do the data transmission. DDC/CI capability allows monitor controls to be sent via the
software for remote diagnostics.
DVI-I
DVI-I, short for Digital Visual Interface-Integrated. A DVI Integrated connectors accept both
digital and analog signals.
Gamma
Gamma is a measurement of the amount of contrast in an image according to the properties of a
gradation curve. With low gamma values, the images will be whitish on the screen, while high
gamma values will display high contrast images.
Hue
Hue is determined by the color’s dominant wavelength within optical spectrum, or visible
spectrum, of light. The spectrum is usually divided into six basic hues: red, yellow, green, blue,
cyan, and magenta.
MAC Standard (MAC STD.)
This mode offers default color temperature and gamma settings for MAC OS systems. The same
colors viewed on a Mac and PC may vary because of the gamma differences. A PC typically has a
higher gamma value. Defaulted color temperature settings of the MAC Standard mode is 6500 K
and its gamma parameter is 1.8.
