作業系統已非同步損毀符合這個控制碼的監視器，因為作業系統的狀態已變更。這個錯誤的發生原因，通常是與這個控制碼關聯的監視器 PDO 已移除、與這個控制碼關聯的監視器 PDO 已停止，或顯示模式已經變更。當視窗傳送 WM_DISPLAYCHANGE 視窗訊息到應用程式時，就會改變顯示模式。

The operating system asynchronously destroyed the monitor which corresponds to this handle because the operating system's state changed. This error typically occurs because the monitor PDO associated with this handle was removed, the monitor PDO associated with this handle was stopped, or a display mode change occurred. A display mode change occurs when windows sends a WM_DISPLAYCHANGE windows message to applications.
