Running App In Secondary Monitor By Default

I have a dual monitor setup. I want my app to run in the secondary monitor by default (through settings in my app). I have been browsing the net for a solution and I found a solution which is setting the Form.Bounds to the Bounds of the secondary monitor. My problem is that if I set the bounds of my newly created form, when it gets displayed, it doesn't show in the secondary monitor.

private void button2_Click(object sender, EventArgs e){
Form1 frm = new Form1();
frm.SetBounds(-1280, 112, frm.Bounds.Width, frm.Bounds.Height);
MessageBox.Show(string.Format("frm.Bounds [{0},{1}]",frm.Bounds.Left,frm.Bounds.Top));
//frm.Bounds = Screen.AllScreens[1].Bounds;
//frm.Location = Screen.AllScreens[1].Bounds.Location;
frm.Show();
MessageBox.Show(string.Format("frm.Bounds [{0},{1}]", frm.Bounds.Left, frm.Bounds.Top));}

In the code above, I first set the bounds, I can see from the message box the settings I assigned. After form gets displayed, I checked the bounds again, it has changed to it's default. How do I show then a newly created form to a specific Bounds?
