A window cannot go full screen properly across multiple screens

[huangbaohua11]

Here is my code. I want a window to be full screen across multiple screens, but I found that when I use the following screen arrangement and scaling, it doesn't work correctly。

    public MainWindow()
    {
        InitializeComponent();
       
        Width = SystemParameters.VirtualScreenWidth;
        Height = SystemParameters.VirtualScreenHeight;
        Left = SystemParameters.VirtualScreenLeft;
        Top = SystemParameters.VirtualScreenTop;
        Console.WriteLine($"Left:{Left},Top:{Top},Width:{Width},Height:{Height}");
    }

My project has PerMonitorV2 DPI awareness enabled and My project use .netframework 4.8.
