Problem
Monitor settings aren’t automatically detected

Cause
Your monitor may not be Plug-and-Play. Most new monitors are Plug-and-Play but many
older ones aren’t. Software can’t automatically detect settings for monitors that aren’t Plug-
and-Play.
1
Solution
Manually select your monitor settings in the software. For Windows 95/98/2000 or NT 4.0,
see “Monitor setup”, page 6
.
2
Cause
If a monitor was changed or added while Windows was running, the new monitor may not
be detected by the software.

Solution
Restart your computer. If your monitor is a Plug-and-Play (DDC) monitor, it should be
automatically detected by the software.
