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.
DICOM (Digital Imaging and Communication in Medicine)
DICOM is a standard for digital imaging and communication for medical use developed by
American College of Radiology and National Electric Manufacturers Association.
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 filter. 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 filter.
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.
