CIM_DisplayController class

Represents the capabilities and management of the display controller.

Important  The DMTF (Distributed Management Task Force) CIM (Common Information Model) classes are the parent classes upon which WMI classes are built. WMI currently supports only the CIM 2.x version schemas.

The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties.

Status

Data type: string

Access type: Read-only

String that indicates the current status of the object. Operational and non-operational status can be defined. Operational status can include "OK", "Degraded", and "Pred Fail". "Pred Fail" indicates that an element is functioning properly, but is predicting a failure (for example, a SMART-enabled hard disk drive).

Nonoperational status can include "Error", "Starting", "Stopping", and "Service". "Service" can apply during disk mirror-resilvering, reloading a user permissions list, or other administrative work. Not all such work is online, but the managed element is neither "OK" nor in one of the other states. This property is inherited from CIM_ManagedSystemElement.

Values include the following:

"OK"

"Error"

"Degraded"

"Unknown"

"Pred Fail"

"Starting"

"Stopping"

"Service"

"Stressed"

"NonRecover"

"No Contact"
