Action

1Check the system and power connections to the monitor.

2Determine whether the system has monitors attached to both the front and rear video connectors.

The system supports only one monitor attached to either the front or rear video connector. When a monitor is connected to the front panel, and the back-panel video connector is disabled.

If two monitors are attached to the system, disconnect one monitor. If the problem is not resolved, continue to the next step.

3Check the system and power connections to the monitor.

4Run the appropriate online diagnostic test. See "Using Dell PowerEdge Diagnostics" on page 117.

If the tests run successfully, the problem is not related to video hardware. If the tests fail, see "Getting Help" on page 127.
