Problem
The RGB switch on the back of
the monitor is incorrectly set.
If the graphics controller was
upgraded, the correct display
drivers may not be loaded.
You may have a screen
blanking utility installed or
energy saver features are
enabled.
The monitor connections may
be incomplete or the monitor
may be incorrectly adjusted.
There is not enough ventilation
space for proper airflow.
Cause
Set the RGB switch (and sync
options, if this option is available) to
75 ohms, with the sync set to
"external." Refer to the
documentation included with the
monitor.
Install the display drivers on the
diskette included in the upgrade kit.
Press any key or type password.
1.
Be sure the monitor cable is
securely connected to the
workstation.
2.
In a 2-monitor system or if
another monitor is in close
proximity, be sure the
monitors are not interfering
with each other's
electromagnetic field by
moving them apart.
Leave at least 3 inches (7.6 cm) of
ventilation space. Be sure there is
nothing sitting on top of the monitor
obstructing the air flow.
