Windows.Devices.Display.Core Namespace

Provides ways to manage and present content to the hardware display pipeline for custom compositor software.

For conceptual documentation on how to implement a custom compositor, see Building a custom compositor app for head-mounted and specialized monitors.

For a sample application, see the Windows.Devices.Display.Core custom compositor sample.

Classes

DisplayAdapter	Represents a hardware display controller. This is typically a GPU (graphics processing unit).
DisplayDevice	Represents a context for creating and presenting content directly to the display driver. A DisplayDevice is analogous to a Direct3D device in the Direct3D API. DisplayDevice objects also implement the COM interface IDisplayDeviceInterop.
DisplayFence	Represents a fence object that can be used to synchronize rendering commands between Direct3D devices and a DisplayDevice object.
DisplayManager	Manages the ownership of a DisplayTarget object or objects, and provides methods to create DisplayState objects.
DisplayManagerChangedEventArgs	Represents arguments for the Changed event.
DisplayManagerDisabledEventArgs	Represents arguments for the Disabled event.
DisplayManagerEnabledEventArgs	Represents arguments for the Enabled event.
DisplayManagerPathsFailedOrInvalidatedEventArgs	Represents arguments for the PathsFailedOrInvalidated event.
DisplayManagerResultWithState	Contains the status of a DisplayManager operation, and a resulting DisplayState if the operation was successful.
DisplayModeInfo	Describes valid combinations of properties for a DisplayPath. The property values on this object can be set on a DisplayPath using the ApplyPropertiesFromMode method. Note that this object refers to a range of valid wire formats, not just one specific wire format.
DisplayPath	Represents a display pipeline path from a logical "source" to a DisplayTarget. A logical source provides a frame buffer, in a format described by the source properties. The display pipeline composes the source content and transforms it into the format described by the target properties. DisplayPath objects also implement the COM interface IDisplayPathInterop.
DisplayPrimaryDescription	Describes a set of properties that are used for allocating DisplaySurface objects using CreatePrimary.
DisplayScanout	Represents a set of validated parameters to scan out content to a source. A DisplayScanout can be assigned to a DisplayTask and executed on a DisplayTaskPool.
DisplaySource	Provides ownership of a source, allowing the owner to present frames.
DisplayState	Represents a slice in time of display pipeline state for a subset of the system's display targets. If IsReadOnly is false, then this object can be modified by connecting targets that are owned by the caller's DisplayManager, or by modifying path properties. Modifying a DisplayState object, or its child objects, does not directly modify the system's display state until you call TryApply.
DisplayStateOperationResult	Contains the status of a DisplayState operation.
DisplaySurface	A 2D pixel buffer that was allocated to be compatible with scanning out to one or more DisplaySource objects.
DisplayTarget	Represents a slice in time of a logical "target" for the display pipeline. This is typically analogous to a physical connector on a GPU, such as an HDMI port, but it can be a virtual target representing daisy-chained DisplayPort targets.
DisplayTask	Represents a set of operations that can be queued and executed atomically by display hardware.
DisplayTaskPool	Provides methods to allocate and execute tasks on a DisplayDevice.
DisplayTaskResult	Represents multiple pieces of feedback/info regarding the state of a presentation request, and what you should do about it. A DisplayTaskResult object is returned from DisplayTaskPool.TryExecuteTask.
DisplayView	Represents a group of DisplayPath objects that are logically cloned together.
DisplayWireFormat	Specifies an exact hardware representation used to scan out; such as the pixel encoding, bits per channel, color space, and HDR metadata format.

Structs

DisplayPresentationRate

Describes an overall presentation rate composed of a rational refresh rate and a divider.

Enums

DisplayBitsPerChannel	Defines constants that specify a number of bits per channel, as flags.
DisplayDeviceCapability	Defines constants that specify a capability of a DisplayDevice.
DisplayManagerOptions	Defines constants that specify options for the DisplayManager.
DisplayManagerResult	Defines constants that specify the result of a DisplayManager operation.
DisplayModeQueryOptions	Defines constants that specify options for a mode query operation.
DisplayPathScaling	Defines constants that specify how to scale content from a frame buffer to a target.
DisplayPathStatus	Defines constants that specify the last status of the path in the system, captured when the DisplayState was last created or applied.
DisplayPresentStatus	Defines constants that specify a detailed status of the result of the most recent call to DisplayTaskPool.TryExecuteTask.
DisplayRotation	Defines constants that specify how to rotate content from a frame buffer to a target.
DisplayScanoutOptions	Defines constants specifying options for creating a DisplayScanout object (for example, by calling DisplayDevice.CreateSimpleScanoutWithDirtyRectsAndOptions).
DisplaySourceStatus	Defines constants that specify a state that a display source (a DisplaySource object) can be in. The state affects the display source's usage, and how it affects other API calls. For example, if a display source is powered off, then you can expect that a call to (for example) DisplayTaskPool.TryExecuteTask won't be successful.
DisplayStateApplyOptions	Defines constants that specify options for applying a DisplayState to the system.
DisplayStateFunctionalizeOptions	Defines constants that specify options for functionalizing a DisplayState with the system.
DisplayStateOperationStatus	Defines constants that specify the result of a DisplayState operation.
DisplayTargetPersistence	Defines constants that specify how a monitor connected to a target should be virtually persisted when the hardware no longer reports any connected monitor.
DisplayTaskSignalKind	Defines constants that specify a signal kind.
DisplayWireFormatColorSpace	Defines constants that specify a color space, typically defined by combinations of three color primaries (red, green, and blue).
DisplayWireFormatEotf	Defines constants that specify an electro-optical transfer function (EOTF) for encoded pixels. The EOTF defines how a pixel's encoded value is transformed to an optical brightness on a hardware display.
DisplayWireFormatHdrMetadata	Defines constants that specify a format for HDR mastering metadata embedded in a pixel bitstream. HDR mastering metadata typically defines how a video stream should be adapted for playback on specific display hardware.
DisplayWireFormatPixelEncoding	Defines constants that specify the color model and chroma subsampling format used to encode pixel data.
