Article
01/07/2021

The WmiMonitorBasicDisplayParams WMI class represents the basic display features of a computer monitor. The value of the VideoInputType property indicates whether the monitor is analog or digital. Data in this class corresponds to data in the Basic Display Parameters/Features block of Video Electronics Standard Association (VESA) Enhanced Extended Display Identification Data (E-EDID) standard.

Syntax

class WmiMonitorBasicDisplayParams : MSMonitorClass
{
  boolean                            Active;
  uint8                              DisplayTransferCharacteristic;
  string                             InstanceName;
  uint8                              MaxHorizontalImageSize;
  uint8                              MaxVerticalImageSize;
  SupportedDisplayFeaturesDescriptor SupportedDisplayFeatures;
  uint8                              VideoInputType;
};

Properties

Properties

The WmiMonitorBasicDisplayParams class has these properties.

Active

Data type: boolean
Access type: Read-only

Indicates the active monitor.

DisplayTransferCharacteristic

Data type: uint8
Access type: Read-only

Display transfer characteristic (100*Gamma-100).

InstanceName

Data type: string
Access type: Read-only
Qualifiers: Key

Name of the specific monitor instance.

MaxHorizontalImageSize

Data type: uint8
Access type: Read-only

Maximum horizontal image size in centimeters. For more information, see Remarks.

MaxVerticalImageSize

Data type: uint8
Access type: Read-only

Maximum vertical image size in centimeters. For more information, see Remarks.

SupportedDisplayFeatures

Data type: SupportedDisplayFeaturesDescriptor
Access type: Read-only

Display features supported by the monitor.

VideoInputType

Data type: uint8
Access type: Read-only

Video input type.

Value	Meaning
0 (0x0)	Analog
1 (0x1)	Digital

Remarks

MaxHorizontalImageSize and MaxVerticalImageSize represent the maximum image dimensions that the monitor can correctly display for the entire set of supported timing and format combinations. The maximum image dimension is defined by VESA Video Image Area Definition (VIAD) Standard and is rounded to the nearest centimeter. The host computer system can use this data to select the image size and aspect ratio that will allow properly scaled text. Be aware that, if either or both of these fields are zero, then the system makes no assumptions about the display size. For example, the size of a projection display may be undetermined.
