Glossary
Clock
The analog input monitor needs to reproduce a clock of the same frequency as the dot clock of the graphics system in
use, when the analog input 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
Color space is a method to specify and express the color. There are YUV and RGB, etc. YUV expresses the color by
using the luminance (Y), the color difference of R (U) and the color difference of blue (V). RGB does it by using the
gradation of 3 colors of Red (R, Green (G) and Blue (B).
ContrastEnhancer
ContrastEnhancer functions to reproduce images with a taste of contrast by compensating the gamma value as well as
controlling the backlight brightness and the gain level according to the image status.
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 input signal only. The other is a DVI-I connector for both digital and analog input
signals. The monitor is not applicable to the DVI-I input signal.
Field Rate
This is the number of times the monitor screen is redrawn in 1 second. The number of times differs depending on the
Video standard.
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 Ilter. 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 Ilter.
Gamma
Generally, the monitor brightness varies nonlinearly with the input signal level, which is called “Gamma
Characteristic”. A small gamma value produces a low-contrast image, while a large gamma value produces a high-
contrast image.
HDCP (High-bandwidth Digital Contents Protection)
Digital signal coding system developed to copy-protect the digital contents, such as video, music, etc. This helps
to transmit the digital contents safely by coding the digital contents sent via DVI terminal on the output side and
decoding them on the input side.
Digital content cannot be reproduced if both the devices on the output and input sides are not applicable to the HDCP
system.
