I want to display a Window on secondary monitor, as follows:

Queue<string> itemQueue = new Queue<string>();

MonitorWindow monitor = new MonitorWindow(itemQueue);

var secondaryScreen = System.Windows.Forms.Screen.AllScreens.Where(s => !s.Primary)
                                                            .FirstOrDefault();

if (secondaryScreen != null)
{
     monitor.WindowStartupLocation = WindowStartupLocation.Manual;
     var workingArea = secondaryScreen.WorkingArea;
     monitor.Left = workingArea.Left;
     monitor.Top = workingArea.Top;
     monitor.Width = workingArea.Width;
     monitor.Height = workingArea.Height;
     monitor.Show();

}

The properties have correct values, but this maximizes the Window on the primary monitor. can you help me?

Ok, I've fixed the problem with remove the property WindowState="Maximized" in XAML code of MonitorWindow and changed the program as follows:

        Queue<string> itemQueue = new Queue<string>();

        MonitorWindow monitor = new MonitorWindow(itemQueue);

        var secondaryScreen = System.Windows.Forms.Screen.AllScreens.Where(s => !s.Primary).FirstOrDefault();

        if (secondaryScreen != null)
        {
            if (!monitor.IsLoaded)
                monitor.WindowStartupLocation = WindowStartupLocation.Manual;
            var workingArea = secondaryScreen.WorkingArea;
            monitor.Left = workingArea.Left;
            monitor.Top = workingArea.Top;
            monitor.Width = workingArea.Width;
            monitor.Height = workingArea.Height;
            // If window isn't loaded then maxmizing will result in the window displaying on the primary monitor
            monitor.Show();
            if (monitor.IsLoaded)
                monitor.WindowState = WindowState.Maximized;
        }
