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.
DisplayPort
This is the interface standard for image signals standardized in accordance with VESA. It was
developed with the aim of replacing the conventional DVI and analog interfaces, and it can transmit
high resolution signals and sound signals, which DVI does not support. The standard size and mini
size connectors have been standardized.
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.
HDCP (High-bandwidth Digital Content Protection)
Digital signal coding system developed to copy-protect the digital contents, such as video, music,
etc.
This helps to transmit the digital contents safely by coding the digital contents sent via the DVI or
HDMI connector on the output side and decoding them on the input side.
Any digital contents cannot be reproduced if both of the equipments on the output and input sides
are not applicable to HDCP system.
