M:Windows.Devices.Display.DisplayMonitor.FromIdAsync(System.String)	winrt method

Windows.Devices.Display.DisplayMonitor.FromIdAsync

-description

Asynchronously creates a DisplayMonitor object for the specified device identifier (a string containing a PnP device instance path). See the code example below.

Note

The argument must be a device identifier, and not a device interface identifier. If you have a device interface identifier (which is likely), then call FromInterfaceIdAsync instead. For more details, see DeviceInformation.Id.

-parameters

-param deviceId

The monitor device identifier. See DeviceInformation.Id.

-returns

An asynchronous create operation.
