DisplayManager.PathsFailedOrInvalidated Event

Definition

Namespace:

Windows.Devices.Display.Core

An event that is raised whenever a display path is failed or invalidated asynchronously by the system. This can be due to changing hardware bandwidth requirements, or due to driver failures.

Subscribers to this event should call TryAcquireTargetsAndReadCurrentState for targets that they own, and check whether any of the paths in the resulting DisplayState object have their Status property set to FailedAsync or InvalidatedAsync, and take the recommended action.
