Clock
The analog signal input monitor needs to reproduce a clock of the same frequency as the dot clock of the
graphics system in use, when the analog 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.
DDC/CI (Display Data Channel/Command Interface)
VESA provides the standardization for the interactive communication of the setting information, etc.
between a PC and the monitor.
DICOM (Digital Imaging and Communication in Medicine)
The DICOM standard was developed by the American College of Radiology and the National Electrical
Manufacturer's Association of the USA.
The DICOM compatible device connection enables to transfer the medical image and information. The
DICOM, Part 14 document defines the digital, grayscale medical image display.
DisplayPort
VESA provides the digital interface standard for the digital display device. DisplayPort can transfer the
video signal up to 16 bits for each channel of RGB, and the audio signal too. (This monitor supports the 8-bit
video signal only.)
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
high-contrast image.
