Possible Cause
You are using a fixed-sync
monitor and it won't sync at
the resolution chosen.
Monitor without energy saver
capabilities is being used
with energy saver features
enabled.
If the graphics controller was
upgraded, the correct display
drivers may not be loaded.
Monitor cable may be loose.
In a 2-monitor system or if
another monitor is in close
proximity, the monitors may
interfere with each other's
magnetic field.
There is not enough ventilation
space for proper airflow.
This indicates that either the
cabling or monitor
impedance is* incorrect.

Possible Solution
Be sure that the monitor
can support the selected
resolution and refresh
rate.
Disable monitor energy
saver feature.
Refer to the documentation
in the upgrade kit for more
information on display
drivers.
Be sure the monitor
cable is securely
connected to the
workstation.
Move the monitors
farther apart.
Leave at least 3 inches
(7.6 cm) of ventilation
space. Also, be sure
there is nothing on top of
the monitor to obstruct
airflow.
1. Ensure that the Red,
Green, and Blue BNC
cables are connected to
the corresponding
monitor connectors.
2. Be sure your monitor's
RGB inputs are set to
75 ohms.
