Troubleshooting Your System

Action
1 Check the system and power connections to the monitor.
2 Determine whether the system has an expansion card with a video output
connector.
In this system configuration, the monitor cable should normally be
connected to the connector on the expansion card,
not to the system’s
integrated video connector.
To verify that the monitor is connected to the correct video connector,
turn off the system and wait for 1 minute, then connect the monitor to the
other video connector and turn the system on again.
3 Run the appropriate online diagnostic test (see "Using Dell PowerEdge
Diagnostics" on page 163).
If the tests run successfully, the problem is not related to video hardware.
If the tests fail, see "Getting Help" on page 175.

and then reconnect them.
