reproduction range (color gamut) is broader than sRGB, and is highly adaptable to such fields as printing etc.
DCI (Digital Cinema Initiatives)
The company was founded by an association of U.S. film studios, and this company decides the
specifications for digital cinema.
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.
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.
EBU (European Broadcasting Union)

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.
