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.

Solution
Manually select your monitor settings in the software. For Windows 2000/XP or NT 4.0, see
“Monitor setup”, page 8.

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.
