CIM_VideoControllerResolution class

Article
01/06/2021

The CIM_VideoControllerResolution class represents the various video modes that a video controller can support. Video modes are defined by the possible horizontal and vertical resolutions, refresh rate, scan mode, and number of color settings supported by a controller. The actual resolutions in use are the values specified in the CIM_VideoController object.

Hardware that is not compatible with Windows Display Driver Model (WDDM) returns inaccurate property values for instances of this class.

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 its inherited properties. Properties are listed in alphabetic order, not MOF order.

Properties

Properties

The CIM_VideoControllerResolution class has these properties.

Caption

Data type: string
Access type: Read-only
Qualifiers: MaxLen (64)

Short textual description of the current object.

This property is inherited from CIM_Setting.

Description

Data type: string
Access type: Read-only

Textual description of the current object.

This property is inherited from CIM_Setting.

HorizontalResolution

Data type: uint32
Access type: Read-only
Qualifiers: ModelCorrespondence ("CIM_VideoController.CurrentHorizontalResolution"), MappingStrings ("MIF.DMTF|Monitor Resolutions|002.2"), Units ("pixels")

Horizontal resolution, in pixels.

MaxRefreshRate

Data type: uint32
Access type: Read-only
Qualifiers: ModelCorrespondence ("CIM_VideoController.MaxRefreshRate"), MappingStrings ("MIF.DMTF|Monitor Resolutions|002.7"), Units ("hertz")

Maximum refresh rate when a range of rates is supported at the specified resolutions, in hertz.

MinRefreshRate

Data type: uint32
Access type: Read-only
Qualifiers: ModelCorrespondence ("CIM_VideoController.MinRefreshRate"), MappingStrings ("MIF.DMTF|Monitor Resolutions|002.6"), Units ("hertz")

Minimum refresh rate when a range of rates is supported at the specified resolutions, in hertz.

NumberOfColors

Data type: uint64
Access type: Read-only
Qualifiers: ModelCorrespondence ("CIM_VideoController.CurrentNumberOfColors")

Number of colors supported at the current resolution.

For more information about using uint64 values in scripts, see Scripting in WMI.

RefreshRate

Data type: uint32
Access type: Read-only
Qualifiers: ModelCorrespondence ("CIM_VideoController.CurrentRefreshRate"), MappingStrings ("MIF.DMTF|Monitor Resolutions|002.4"), Units ("hertz")

Refresh rate, in hertz. If a range of rates is supported, use the MinRefreshRate and MaxRefreshRate properties, and set this property to 0.

ScanMode

Data type: uint16
Access type: Read-only
Qualifiers: ModelCorrespondence ("CIM_VideoController.CurrentScanMode"), MappingStrings ("MIF.DMTF|Monitor Resolutions|002.5")

Scan mode at which the controller operates.

Other (1)

Unknown (2)

Not Supported (3)

Non-Interlaced Operation (4)

Noninterlaced operation

Interlaced Operation (5)

SettingID

Data type: string
Access type: Read-only
Qualifiers: Override ("SettingID"), Key, MaxLen (256)

An ID that serves as part of the key for the current instance.

VerticalResolution

Data type: uint32
Access type: Read-only
Qualifiers: ModelCorrespondence ("CIM_VideoController.CurrentVerticalResolution"), MappingStrings ("MIF.DMTF|Monitor Resolutions|002.3"), Units ("pixels")

Controller's vertical resolution, in pixels.

Remarks

WMI implements the CIM_VideoControllerResolution class. The CIM_VideoControllerResolution class is a dynamic class.

This documentation is derived from the CIM class descriptions published by the DMTF. Microsoft may have made changes to correct minor errors, conform to Microsoft SDK documentation standards, or provide more information.

Note that this class is a base class. If you are attempting to access your video controller through WMI, you may wish to use Win32_VideoController instead.
