SystemConfig_V0_Video class

This class is the event type class for video configuration events.

The following syntax is simplified from MOF code.

• Properties

Properties

The SystemConfig_V0_Video class has these properties.

AdapterString

Data type: char16 array

Access type: Read-only

Qualifiers: WmiDataId (8), Max (256)

Name or description of the adapter.

BiosString

Data type: char16 array

Access type: Read-only

Qualifiers: WmiDataId (9), Max (256)

BIOS name of the adapter.

BitsPerPixel

Data type: uint32

Access type: Read-only

Qualifiers: WmiDataId (4)

Number of bits used to display each pixel.

ChipType

Data type: char16 array

Access type: Read-only

Qualifiers: WmiDataId (6), Max (256)

Chip name of the adapter.

DACType

Data type: char16 array

Access type: Read-only

Qualifiers: WmiDataId (7), Max (256)

Digital-to-analog converter (DAC) chip name of the adapter.

DeviceId

Data type: char16 array

Access type: Read-only

Qualifiers: WmiDataId (10), Max (256)

Address or other identifying information to uniquely name the logical device.

MemorySize

Data type: uint32

Access type: Read-only

Qualifiers: WmiDataId (1)

Maximum amount of memory supported, in bytes.

StateFlags

Data type: uint32

Access type: Read-only

Qualifiers: WmiDataId (11)

Device state flags. It can be any reasonable combination of the following.

Value	Meaning
DISPLAY_DEVICE_ATTACHED_TO_DESKTOP 1 (0x1)	The device is part of the desktop.
DISPLAY_DEVICE_MIRRORING_DRIVER 8 (0x8)	Represents a pseudo device used to mirror application drawing for connecting to a remote computer or other purposes. An invisible pseudo monitor is associated with this device. For example, NetMeeting uses it.
DISPLAY_DEVICE_MODESPRUNED 134217728 (0x8000000)	The device has more display modes than its output devices support.
DISPLAY_DEVICE_PRIMARY_DEVICE 4 (0x4)	The primary desktop is on the device. For a system with a single display card, this is always set. For a system with multiple display cards, only one device can have this set.
DISPLAY_DEVICE_REMOVABLE 32 (0x20)	The device is removable; it cannot be the primary display.
DISPLAY_DEVICE_VGA_COMPATIBLE 16 (0x10)	The device is VGA compatible.

 

VRefresh

Data type: uint32

Access type: Read-only

Qualifiers: WmiDataId (5)

Current refresh rate, in hertz.

XResolution

Data type: uint32

Access type: Read-only

Qualifiers: WmiDataId (2)

Current number of horizontal pixels.

YResolution

Data type: uint32

Access type: Read-only

Qualifiers: WmiDataId (3)

Current number of vertical pixels.
