5-1  Attaching an Arm
The stand can be removed and replaced with an arm (or another stand) to be 
attached to the monitor. Use an arm or stand of EIZO option.
[Attaching]
1  Lay the LCD monitor on a soft cloth spread over on a stable 
surface with the panel surface facing down.
2  Remove the stand. (Prepare a screwdriver.)
Unscrew the four screws securing the unit and the stand with the 
screwdriver.
3  Attach the monitor to the arm or stand.Secure the monitor to the arm or stand using the screws specified in the 
user’s manual of the arm or stand.
Attention
•  When attaching an arm or stand, follow the instructions of their user’s 
manual.
•  When using another manufacturer’ s arm or stand, confirm the following 
in advance and select one conforming 
to the VESA standard. Use the M4 
× 12 mm screws supplied with this 
monitor.
– Clearance between the screw holes: 
100 mm × 100 mm
– Thickness of plate: 2.6 mm
– Strong enough to support weight of 
the monitor unit (except the stand) 
and attachments such as cables.
•  When using an arm or stand, attach it  to meet the following tilt angles of the 
monitor.
– Up 45 degrees, down 45 degrees (horizontal display, and vertical 
display rotated 90 degrees 
clockwise)
•  Connect the cables after attaching an 
arm.
•  If you need to remove the EZ-UP 
stand, turn the panel on the monitor 
to the left and right a little to appear 
the four screws positioned under the 
stand. Then unscrew the four screws.

Attention
•  Never use any solvents or chemicals, such as thinner, benzene, wax, 
alcohol, and abrasive cleaner, which 
may damage the cabinet or LCD 
panel.
NOTE
•  Optional ScreenCleaner is 
recommended for cleaning the LCD 
panel surface.
5-2  Cleaning
Clean the monitor periodically to keep the monitor clean and extend its life.
Cabinet
Clean the cabinet with a soft cloth dampened with little mild deter gent.
LCD Panel
•  Clean the LCD panel with a soft cloth such as cotton cloth or lens cleaning 
paper. 
•  Remove persistent stains gently with a cloth dampened with little water, and  then clean the LCD panel again with a dry cloth for better finishing.

5-4  Glossary
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.
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.
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.
GainThis 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 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.
Resolution The LCD panel consists of numerous pixels of specified size, which are illuminated to form images. This monitor 
consists of 1680 horizontal pixels and 1050 vertical pixels. At a resolution of 1680 x 1050, all pixels are illuminated 
as a full screen (1:1).
 
						

							
37Chapter 5  Reference

sRGB (Standard RGB)
International standard for “color reproduction and color space” among peripheral devices (such as monitors, printers, 
digital cameras, scanners). sRGB allows Internet users to closely match colors as a simple color matching means for 
the Internet use.
Temperature Color temperature is a method to measure the white color tone, generally indicated in degrees Kelvin.  The screen 
becomes reddish at a low temperature, and bluish at a high temperature, like the fl ame temperature.
5000K: Slightly reddish white
6500K: Warm white like paper white
9300K: Slightly bluish white
TMDS (Transition Minimized Differential Signaling) A signal transmission system for digital interface.
VESA DPMS (Video Electronics Standards Association - Display Power Management Signaling) VESA provides the standardization of signals from PC (graphics board) for power saving of PC monitors. DPMS 
defines the signal status between PC and monitor.

Attention
•  Display position may be deviated 
depending on the PC connected, 
which may require screen adjustment 
using Adjustment menu.
•  If a signal other than those listed in 
the table is input, adjust the screen 
using the Adjustment menu. However, 
screen display may still be incorrect 
even after the adjustment.
•  When interlace signals are used, the 
screen cannot be displayed correctly 
even after screen adjustment using the 
Adjustment menu.
