7-3. Making Use of USB (Universal Serial Bus)
This monitor has a hub compatible with USB. Connected to a PC compatible with USB or another USB 
hub, this monitor functions as a USB hub allowing connection to peripheral USB devices.
●  Required System Environment
1. A PC equipped with a USB port or another USB hub connected to a USB compatible PC
2.  Windows 2000/XP/Vista/7 or Mac OS 9.2.2 and Mac OS X 10.2 or later
3.  EIZO USB cable (MD-C93)
Attention
• This monitor may not work depending on PC, OS or peripheral devices to be used. For USB compatibility of 
peripheral devices, contact their manufactures.
•  Devices connected to the USB port (upstream and downstream) work when the monitor is in power saving 
mode or when the power button of the monitor is Off. Therefore, power consumption of the monitor varies with 
connected devices even in the power saving mode.
•  When the main power switch is Off, device connected to the USB port will not operate.
●  Connection Procedure (Setup of USB Function)
1.  Connect the monitor first to a PC using the signal cable, and run the PC.
2.  Connect the supplied USB cable between the downstream USB port of a USB compatible PC (or 
another USB hub) and the monitor’s upstream USB port.
The USB hub function is set up automatically upon connection of the USB cable.
3. Connect the peripheral USB device to the USB port (downstream) of the monitor.

7-6. Glossary
Adobe® RGB
This is a definition 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 fields as printing 
etc.
Clock
The analog input monitor needs to reproduce a clock of the same frequency as the dot clock of the 
graphics system in use, when the analog input 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.
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. (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.
EBU(European Broadcasting Union)
The organization also includes broadcasting offices from Europe and North Africa, and it’s role is to 
decide various technical standards etc.
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.
  
						

							50Chapter 7  Reference
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 highcontrast image.
HDCP (High-bandwidth Digital Contents 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 DVI terminal 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.
Phase
Phase means the sampling timing to convert the analog input signal to a digital signal. Phase adjustment 
is made to adjust the timing. It is recommended that phase adjustment be made after the clock is adjusted 
correctly.
Range Adjustment
Range adjustment controls the signal output levels to display every color gradation. It is recommended 
that range adjustment be made before color adjustment.
Rec709
Digital broadcasting (HDTV) standards defined by the ITU-R (International Telecommunication Union 
Radio Communication Sector).
Resolution
The LCD panel consists of numerous pixels of specified size, which are illuminated to form images. This 
monitor consists of 1920 horizontal pixels and 1200 vertical pixels. At a resolution of 1920 x 1200, all 
pixels are illuminated as a full screen (1:1).
SMPTE-C
One of the standards provided by the SMPTE (Society of Motion Picture and Television Engineers).
sRGB	(Standard RGB)
“International Standard for Red, Green, and Blue color space” A color space was defined with the aim of 
the color matching between applications and hardware devices, such as monitors, scanners, printers and 
digital cameras. As a standard default space, sRGB allows Internet users to closely match colors.
