10. GLOSSARY
Clock
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 flat 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 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
Gain Adjustment
Adjusts each color parameter for red, green and blue. The color of the LCD monitor is displayed through the color filter 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 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.
Phase
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.
