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.
DisplayPort
DisplayPort is a next-generation digital AV interface that allows connection of the PC, audio, imaging
devices, etc. to the monitor. One cable can transfer sound with images.
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 lter. 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 lter.
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 highcontrast image.
