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.
Color Temperature (Temperature)
Color Temperature is a method to measure the white color tone, generally
indicated in degrees Kelvin. At high temperatures the white tone appears
somewhat blue, while at lower temperatures it appears somewhat red. Computer
monitors generally give best performance at high temperature settings.
5,000 K: Slightly reddish white.
6,500 K: Warm-white tone, similar to white paper or daylight.
9,300 K: Slightly bluish white.
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-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 monitor’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 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.
