✅ WPF - Detect if screen resolution is resized (ex. 125% or more)

private void Button_Click(object sender, RoutedEventArgs e)
{
    bool isResizing = true;
    if (isResizing)
    {
        MessageBox.Show((SystemParameters.PrimaryScreenWidth * 1.25).ToString());
        MessageBox.Show((SystemParameters.PrimaryScreenHeight * 1.25).ToString());
    }
    else
    {
        MessageBox.Show((SystemParameters.PrimaryScreenWidth).ToString());
        MessageBox.Show((SystemParameters.PrimaryScreenHeight).ToString());
    }
}

int resizingPercent = 25;
