Showing a Windows form on a secondary monitor?

I'm trying to set a Windows Form on secondary monitor, as follows:

private void button1_Click(object sender, EventArgs e)
{
    MatrixView n = new MatrixView();
    Screen[] screens = Screen.AllScreens;
    setFormLocation(n, screens[1]);
    n.Show();
}

private void setFormLocation(Form form, Screen screen)
{
    // first method
    Rectangle bounds = screen.Bounds;
    form.SetBounds(bounds.X, bounds.Y, bounds.Width, bounds.Height);

    // second method
    //Point location = screen.Bounds.Location;
    //Size size = screen.Bounds.Size;

    //form.Left = location.X;
    //form.Top = location.Y;
    //form.Width = size.Width;
    //form.Height = size.Height;
}

The properties of bounds seem correct, but in both methods I've tried, this maximizes the form on the primary monitor. Any ideas?

This method shows forms on selected screen from left to right:

void ShowFormsOnScreenLeftToRight(Screen screen, params Form[] forms)
    {
        if (forms == null || forms.Length == 0)
            return;

        var formsCnt = forms.Length;
        var formSize = new Size(screen.WorkingArea.Size.Width / formsCnt, screen.WorkingArea.Size.Height);
        for (var i = 0; i < formsCnt; i++)
        {
            var form = forms[i];
            if (form == null)
                continue;
            form.WindowState = FormWindowState.Normal;
            form.Location = new Point(screen.WorkingArea.Left + screen.WorkingArea.Size.Width / formsCnt * i, 0);
            form.Size = formSize;
            form.BringToFront();
        }
    }

To solve your problem, you should run:

ShowFormsOnScreenLeftToRight(n, Screen.AllScreens.First(s => !s.Primary));

  Screen[] screens = Screen.AllScreens;
                sc aoc = new sc();
                aoc.Show();
    aoc.Location = Screen.AllScreens[INDEX OF YOUR AVAILABLE SCREENS TARGET].WorkingArea.Location;

FOR MAXIMIZED WINDOW STATE

aoc.WindowState = FormWindowState.Maximized;

FOR ANY X,Y POSITION

aoc.Location = new Point(TARGET X POSITION, TARGET Y POSITION);
