Adobe RGB
This is a definition of the practical RGB color space proposed by Adobe Systems in 1998. The color
reproduction range (color gamut) is broader than sRGB, and is highly adaptable to such fields as printing etc.
Clock
The analog signal input monitor needs to reproduce a clock of the same frequency as the dot clock of the
graphics system in use, when the analog signal is converted to a digital signal for image display. This is
called clock adjustment. If the clock pulse is not set correctly, some vertical bars appear on the screen.
Color Space
YUV and RGB, etc. are available. YUV expresses the color by using the luminance (Y), the color difference
of Blue (U), and the color difference of Red (V). RGB does this by using the gradation of the 3 colors, Red
(R), Green (G), and Blue (B).
DisplayPort
This is a next-generation digital AV interface used to connect PCs and audio-visual devices to the monitor.
Both the video and sound signals can be transferred using one cable.
DVI (Digital Visual Interface)
DVI is a digital interface standard. DVI allows direct transmission of the PC's digital data without loss.
This adopts the TMDS transmission system and DVI connectors. There are two types of DVI connectors.
One is a DVI-D connector for digital signal input only. The other is a DVI-I connector for both digital and
analog signal inputs.
DVI DMPM (DVI Digital Monitor Power Management)
DVI DMPM is a digital interface power saving function. The "Monitor ON (operating mode)" and "Active
Off (power saving mode)" are indispensable for DVI DMPM as the monitor's power mode.
Gain
This is used to adjust each color parameter for red, green and blue. An LCD monitor displays the color by
the light passing through the panel color filter. Red, green and blue are the three primary colors. All the
colors on the screen are displayed by combining these three colors. The color tone can be changed by
adjusting the light intensity (volume) passing through each color's filter.
Gamma
Generally, the relationship that the light intensity values of a monitor change nonlinearly to the input signal
level is called "Gamma Characteristic". On the monitor, low gamma values display the whitish images and
high gamma values display the high contrast images.
