The monitor is based on the VESA DPMS and the
DVI DMPM 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.
DPMS: Display Power Management Signalling

DMPM: Digital Monitor Power Management

This monitor supports the VESA DDC (Display
Data Channel) standard.
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.

Depending on the computer or OS, it may be
necessary to use the computer to operate the
installation of monitor set-up information etc. If so,

information. (Depending on the type of computer or
OS, command names and methods may differ.
Please follow the computer's own operation manual
while reading this.)

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.
- Windows 98/2000/Me/XP all use the ICC

profile.

- When installing Windows 98/2000/Me/XP 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 on page 26.

- When using an ICC profile, set  [COLOR

MODE] and [WHITE BALANCE] to [STD].
