bool DidDisplayIdChange();

public bool DidDisplayIdChange { get; }

var boolean = contentEnvironmentStateChangedEventArgs.didDisplayIdChange;

Public ReadOnly Property DidDisplayIdChange As Boolean

Property Value

Boolean

bool

True, if the "metrics authority" monitor ID changed; otherwise, false.

Remarks

Although top-level windows may be displayed across multiple monitors, each top-level window gets its metrics from a single monitor (the DisplayId), which might not have the same dots per inch (dpi) as the ContentIsland.RasterizationScale. Although these values typically match, there are cases where they might not, such as when a user changes the monitor topology or a top level window is moved across dpi boundaries.
