c# - Use correct size of WPF SplashScreen for screens with different DPI

Question

I'm using the SplashScreen functionality in my WPF app (e.g. 400x200px PNG file). On screens with standard DPI, SplashScreen is displayed correctly, but on Retina displays or other High-DPI screens it looks very small. It is possible to provide more PNG resources (with different sizes) and choose one based on screen DPI?

My current implememntation (in App.xaml.cs):

    protected override void OnStartup(StartupEventArgs e)
    {
        SplashScreen splash = new SplashScreen("Resources/Images/splash-screen.png");
        splash.Show(true, true);

        base.OnStartup(e);
    }
