DDC (Display Data Channel)
VESA provides the standardization for the intera ctive communication of the setting informat ion, 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 Electr ical
Manufacturer’s Association of the USA.
The DICOM compatible device connection enables to transfer the medical im age and information. The
DICOM, Part 14 document denes the digital, grayscale medical image display.
DisplayPort
VESA provides the digital interface standa rd 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
or 10-bit video signals, but it does not support audio signals.)
DVI (Digital Visual Interface)
DVI is a digital interface standard. DVI allows direct t ransmission of the PC’s digital data without loss.
This adopts the TMDS transmis sion system and DVI connectors. There are two typ es of DVI connectors.
One is a DVI-D connector for digital signal input only. The other is a DVI-I connector for both digital a nd
analog signal inputs.
DVI DMPM (DVI Digital Monitor Power Management)
DVI DMPM is a digital interface power saving function. The “Mon itor 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, gr een and blue. An LCD monitor displays the color by
the light passing through the panel color lter. Red, green and blue are t he three primary colors. All t he
colors on the screen are displayed by combining these three c olors. The color tone can be changed by
adjusting the light intensity (volume) passing through each color’s lter.
Gamma
Generally, the monitor brightness varies nonlinea rly with the input signal level, which is called “Gamma
Characteristic”. A small gamma value produces a low-contra st image, while a large gamma value produces a
high-contrast image.
