Dell PowerEdge R900 - Manual (Page 130)

130 Troubleshooting Your System
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.
3 Determine whether the system has monitors attached to both the front
and back video connectors.
The system supports only one monitor attached to either the front or back
video connector. When a monitor is connected to the front panel, 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.
4 Change the monitor connection from the front to the back (or back to the
front). If the problem is not resolved, continue to the next step.
5 If the Dell Remote Assistant Card (DRAC) is installed and configured,
connect into the DRAC from another computer and run the appropriate
online diagnostic test. See "Using PowerEdge Diagnostics" on page 149.
If the tests run successfully, the problem is not related to video hardware.
If the tests fail, see "Getting Help" on page 165.
