´-². Glossary
With the analog input signal display, the analog signal is converted to a digital signal by the LCD
circuitry. To convert the signal correctly, the LCD monitor needs to produce the same number clock
pulse as the dot clock of the graphics system. When the clock pulse is not correctly set, some vertical
bars of distortion are displayed on the screen.
DVI (Digital Visual Interface)
A digital ²at panel interface. DVI can transmit digital data from the PC directly without loss with the
signal transition method "TMDS". There are two kinds of DVI connectors. One is DVI-D connector
for digital signal input only. The other is DVI-I connector for both digital and analog signal inputs.
DVI DMPM (DVI Digital Monitor Power Management)
The Power management system for the digital interface. The "Monitor ON" status (operation mode)
and the "Active Off" status (power-saving mode) are indispensable for the DVI-DMPM as the moni-
tor's power mode.
Gain Adjustment
Adjusts each color parameter for red, green and blue. The color of the LCD monitor is displayed
through the color ±lter of the LCD panel. Red, green and blue are the three primary colors. The colors
on the monitor are displayed by combining these three colors. The color tone can change by adjusting
the illumination amount passed through each color's ±lter.
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.
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.
Any digital contents cannot be reproduced if both of the equipments on the output and input sides are
not applicable to HDCP system.
The phase adjustment decides the sampling timing point for converting the analog input signal to a
digital signal. Adjusting the phase after the clock adjustment will produce a clear screen.
Range Adjustment
The Range Adjustment controls the level of output signal range to display the whole color gradation.
