DPMS: Display Power Management Signalling
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.

together with an ICC profile, a high color resolution can be realized.
• Windows98, WindowsMe and Windows2000 all use the ICC profile.
• 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 Installingthe ICC profile on page 15.
• When using the ICC profile, please set the [WH ITE BALANC E] to [ ST D].
