DDC (Plug & Play)

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 t hat 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.

Note:
When setting up the monitor or a connected computer for the first

time, connecting an additional computer or after having changed an
aspect of the current system, perform an automatic screen adjust­ment before use

■Automatic adjustment screen display

To perform an automatic adjustment, first display an image that
makes the entire screen very bright. If you are using Windows, you
can also use the Adjustment Pattern on the accompanying Monitor
Settings Adjustment Disk for Windows.

Displaying th e Adjustment Pattern (for Windows)

This explanation is for Windows 95/98/2000, and assumes that the
floppy disk drive is [A drive].

Note: If the floppy disk drive of your computer is not "A drive", please

read the below substituting the floppy disk drive you are using
in place of "A drive" or "A".

1. Place the Monitor Settings Adjustment Disk (provided) into the
computer’s A drive.

2. Open [My Computer] and select [3 Floppy (A:)]. If using Windows

3.1, open [File Manager] and choose "A drive".

3. Double click on [Adj_uty.exe] to run the Adjustment Program. The
Adjustment Pattern will appear.

Notes:• After completing the adjustment, press the computer’s [Esc]

key to exit the Adjustment Program.

• 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 input
signal specification and is not a malfunction.)
