Plug & Play with Windows®

Plug and Play was designed to simplify the installation and configuration of

hardware, such as your monitor, printer, modem, etc.

After turning on your monitor, Windows either "detects" or "does not detect"

your monitor. If your monitor was not detected, make certain that the

following two files have been installed from the diskette/CD-ROM included

with your monitor onto your hard drive.

• VS*.INF (Windows Information for Plug & Play) file, and

• VS*.ICM (ICC Profile for Color Calibration) file.

From the diskette

1With your computer on, insert

the diskette into the

computer's disk drive.

2Click the Windows Start menu

button.

3Select Run.

4Type in A:\install.exe if your

disk drive is A.

Type in B:\install.exe if your

disk drive is B.

5Click OK and follow the

instructions.

6Restart your computer for the

installation to take effect.

From ViewSonic®Display SuiteTM

CD-ROM

1With your computer on, insert the

CD into the CD-ROM drive.

2Wait for the CD to automatically

start.

3Select Windows Plug & Play.

4Select Install.

5Restart your computer for the

installation to take effect.

Note: Windows '98 will automatically

load VS.INF and VS.ICM files.

Restarting your computer will not be

necessary.

DDC Diagnostic Utility

If you have an IBM or compatible computer, you can use the DDC Diagnostic

Utility to test the communication between your monitor and the DDC-

compatible* graphics card in your computer. To install the DDC Diagnostic

Utility, use the ViewSonic diskette or CD-ROM included with your monitor.

•From the diskette, run install.exe.

•From the CD-ROM, press the Test Plug & Play button.

For more information on the DDC Utility, refer to the readme.txt file on the

CD-ROM or diskette. If your monitor still fails to be detected, call customer

support. (See back cover of this manual.)

If you followed the above instructions, and Windows does not detect your

monitor, the DDCTM Diagnostic Utility may provide a solution.

*Some older computer systems are not compatible with the DDC standard. If your

monitor is displaying a monochrome image or the wrong resolution, call customer

support for a non-DDC adapter. If you upgrade to a DDC-compatible system later

and want to use Plug & Play, remove the adapter.
