Example: 3

DitherType
Data type: uint32
Access type: Read-only

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.

ICMIntent
Data type: uint32
Access type: Read-only

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)

ICMMethod
Data type: uint32
Access type: Read-only

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.
