| CreatePeriodicFence(DisplayTarget, TimeSpan) |
Creates a DisplayFence object that is automatically signaled by the system with an incrementing value at a certain time every vertical refresh cycle. |
| CreatePrimary(DisplayTarget, DisplayPrimaryDescription) |
Creates a primary surface (or just "primary") for use with the display controller. The resulting primary surface is compatible with a DisplayScanout, which is used for presenting content directly to the screen. |

Creates a DisplaySource object, which provides the ability to directly scan out/present to the DisplayTarget object or objects currently connected to this source. |
| CreateSimpleScanout(DisplaySource, DisplaySurface, UInt32, UInt32) |
Creates a DisplayScanout object that can be used to present a full-screen surface directly to the screen. |
| CreateSimpleScanoutWithDirtyRectsAndOptions(DisplaySource, DisplaySurface, UInt32, UInt32, IIterable<RectInt32>, DisplayScanoutOptions) |
Creates a DisplayScanout object that provides an immutable encapsulation of parameters required for presenting a frame to a DisplaySource. |
| CreateTaskPool() |
Creates a DisplayTaskPool, which can create and execute DisplayTask objects on this DisplayDevice. |
| IsCapabilitySupported(DisplayDeviceCapability) |
Retrieves a Boolean value indicating whether or not a given capability is supported by this DisplayDevice. |
| WaitForVBlank(DisplaySource) |
Synchronously waits for the next V-blank interrupt to be fired by the primary DisplayTarget for a given DisplaySource. |
