Dither type of the video controller. The property can be one of the predefined values, or a driver-defined value greater than or equal to 256. If line art dithering is chosen, the controller uses a dithering method that produces well-defined borders between black, white, and gray scalings. Line art dithering is not suitable for images that include continuous graduations in intensity and hue such as scanned photographs.

Free-form string supplying more information about the error recorded in LastErrorCode property, and information on any corrective actions that may be taken.
Specific value of one of the three possible color-matching methods or intents that should be used by default. This property is used primarily for non-ICM applications. ICM applications establish intents by using the ICM functions. This property can be a predefined value or a driver defined value greater than or equal to 256. Color matching based on saturation is the most appropriate choice for business graphs when dithering is not desired. Color matching based on contrast is the most appropriate choice for scanned or photographic images when dithering is desired. Color matching optimized to match the exact color requested is most appropriate for use with business logos or other images when an exact color match is desired.
Saturation (1)
Contrast (2)
Exact Color (3)
Method of handling ICM. For non-ICM applications, this property determines if ICM is enabled. For ICM applications, the system examines this property to determine how to handle ICM support. This property can be a predefined value or a driver-defined value greater than or equal to 256. The value determines which system handles image color matching.

Maximum number of directly addressable entities supportable by this controller. A value of 0 (zero) should be used if the number is unknown.
Maximum refresh rate of the video controller in hertz.
Minimum refresh rate of the video controller in hertz.
If TRUE, gray scale is used to display images.
Label by which the object is known. When subclassed, the property can be overridden to be a key property.
Current number of color planes. If this value is not applicable for the current video configuration, enter 0 (zero).

Protocol used by the controller to access "controlled" devices.
ATA or ATAPI
Number of reserved entries in the system palette. The operating system may reserve entries to support standard colors for task bars and other desktop display items. This index is valid only if the device driver sets the RC_PALETTE bit in the RASTERCAPS index, and is available only if the driver is compatible with 16-bit Windows. If the system is not using a palette, ReservedSystemPaletteEntries is not set.
Example: 20
Version number of the initialization data specification (upon which the structure is based).
Current status of the object. Various operational and nonoperational statuses can be defined. Operational statuses include: "OK", "Degraded", and "Pred Fail" (an element, such as a SMART-enabled hard disk drive, may be functioning properly but predicting a failure in the near future). Nonoperational statuses include: "Error", "Starting", "Stopping", and "Service". The latter, "Service", could apply during mirror-resilvering of a disk, reload of a user permissions list, or other administrative work. Not all such work is online, yet the managed element is neither "OK" nor in one of the other states.
Values include the following:
OK ("OK")
Error ("Error")
Degraded ("Degraded")
Unknown ("Unknown")
Pred Fail ("Pred Fail")
Starting ("Starting")
Stopping ("Stopping")
Service ("Service")
Stressed ("Stressed")
NonRecover ("NonRecover")
No Contact ("No Contact")
Lost Comm ("Lost Comm")

Unknown (2)
Enabled (3)
Disabled (4)
Not Applicable (5)
Value of the scoping computer's CreationClassName property.
Name of the scoping system.
Current number of color index entries in the system palette. This index is valid only if the device driver sets the RC_PALETTE bit in the RASTERCAPS index, and is available only if the driver is compatible with 16-bit Windows. If the system is not using a palette, SystemPaletteEntries is not set.
Example: 20
Date and time this controller was last reset. This could mean the controller was powered down or reinitialized.
