Power management
The monitor is based on the VESA DPMS*1 and the DVI DMPM*2
standards.
To activate the monitor’s Power Management function, both the video
card and the computer must conform to the VESA DPMS standard
and the DVI DMPM standard.

DDC (Plug & Play)
This monitor supports the VESA DDC (Display Data Channel) stand-
ard.
DDC is a signal standard for carrying out Plug & Play functions on the
monitor or PC. It transfers information such as degree of resolution
between the monitor and PC. You can use this function if your PC is
DDC compliant and if it is set so that it can detect the Plug & Play
monitor.
There are many varieties of DDC due to the differences between
systems. This monitor works with DDC1 and DDC2B.

About the ICC profile
An ICC (International Color Consortium) profile is a file that describes
the color characteristics of the LCD monitor. By using an application
that works together with an ICC profile, a high color resolution can be
realized.
•Windows98, WindowsMe and Windows2000 all use the ICC pro-
file.
•When installing Windows98, WindowsMe and Windows2000 set-
up information (described below), the ICC profile is also installed. If
you would like to install the ICC program only, please refer to
Installing the ICC profile.
•When using the ICC profile, please set the [WHITE BALANCE] to
[STD] and the [COLOR MODE] to [OFF].

Information about the ColorSync profile (MacOS)
About the ColorSync profile
ColorSync is the Apple Corporation’s color management system and
is a function that enables color resolution to be realized when used
with a compatible application. A ColorSync profile describes the color
characteristics of the LCD monitor.
Notes: •This monitor’s ColorSync profile works with MacOS8.5 or
above.
•When using the ColorSync profile, please set the [WHITE
BALANCE] to [STD] and the [COLOR MODE] to [OFF].

Setting up the ColorSync profile
Notes: •A floppy disk drive is necessary. In addition, it is neces-
sary to have PC Exchange or File Exchange installed in
your system.
•Depending on the type of computer or OS, command
names and methods may differ. Please follow the com-
puter’s own operation manual while reading this.
1. Place the Utility Disk (provided) into the computer’s floppy disk drive.
2. Copy the profile to be used from the Mac folder on the Utility Disk
to the ColorSync profile folder located within the system folder.
3. Using the ColorSync on the control panel, choose the profile to be used.

please read the below substituting the floppy disk drive
you are using in place of "A drive" or "A".
•If your computer’s display mode is set to 65K colors, you
may see the different color levels in each color pattern or
the gray scale may look colored. (This is due to the speci-
fication of the input signal and is not a malfunction.)
(2) MANUAL SCREEN ADJUSTMENT
