Adobe® RGB
This is a denition of the practical RGB color space proposed by Adobe Systems in 1998. The color
reproduction range (color gamut) is broader than sRGB, and is highly adaptable to such elds as printing
etc.
Clock
The analog input monitor needs to reproduce a clock of the same freque ncy as the dot clock of the
graphics system in use, when the analog input signal is conver ted to a digital signal for image display.
This is called clock adjustment. If the clock pulse is not set correctly, some vertical bar s appear on the
screen.
DCI(Digital Cinema Initiatives)
The company was founded by an association of U.S. lm studios, and this compa ny decides the
specications for digital cinema.
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 video signal only.)
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 “Monitor ON (operating mod e)” and
“Active Off (power-saving mode)” are indispensable for DVI DMPM as the monitor’s power mode.
EBU(European Broadcasting Union)
The organization also includes broadcasting ofce s from Europe and North Africa, a nd it’s role is to
decide various technical standards et c.
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
the colors on the screen are displayed by combining these thre e colors. The color tone can be changed by
adjusting the light intensity (volume) passing through each color’s lter.
