ViewSonic G773
Operation
The ViewSonic
G773 uses DDC (Display Data Channel) protocol to
communicate with your computer's video card. The software diskette or CD
included in the ViewSonic G773 package has a utility file called
DDCTEST.EXE. This utility is useful for troubleshooting if DDC-related
problems occur when using Windows
®
3.1 or Windows
®
95.
When you run the DDC Diagnostic Utility, one of two messages will
appear:
1. If the utility detects that DDC is functioning, the following appears:
ViewSonic/Optiquest Plug & Play monitor: G773 successfully detected.
Hit any key to read and decode the EDID information...(ESC to exit)
If you hit a key, you will see information about the monitor. This information
is a table of EDID codes (Extended Display IDentification) and an
explanation of the codes. Press ESC to exit then:
a. Check if DDC is enabled in Windows. Refer to the README.TXT file
on the ViewSonic
diskette for instructions on how to enable DDC in
Windows.
b. Install the ViewSonic MONITOR.INF file included on the ViewSonic
diskette. It is titled VSdatecode.inf, with the date code in year/month/
day. Refer to the README.TXT file on the ViewSonic diskette for
installation instructions.
If Plug & Play still does not work after you have followed the procedure
above, call ViewSonic Customer Support.
2. If the utility detects that DDC is not functioning, the following appears:
ViewSonic/Optiquest Plug & Play monitor was not detected
Exit the utility. Turn the monitor off. Wait ten seconds and turn the monitor
on. Try the DDC Diagnostic Utility again. If you still receive the message that
the monitor was not detected:
a. Check your computer or graphics board manufacturer's user's guide to
see if your graphics system is DDC compatible.
b. Check the video cable connector for bent or broken pins.
c. Refer to the README.TXT file troubleshooting section (included on the
ViewSonic diskette).
If the procedure above does not work, call ViewSonic Customer Support.
