title: Find out which display belongs to which adapter?
body: <p>I'm working on a SlimDX apps which works for multiple display. The apps will occupy the selected display, and it's selection is input via commandline, as int. I then use <code>System.Windows.Forms.Screen.AllScreens[selection]</code> to find out about the bound, and display my apps "fullscreen" on that display.</p>
  
  <p>Now, to optimize performance, I need to select which gpu adapter to initialize the Direct3D's device. How do I find out which gpu adapter is powering the selected display? </p>
  
  <p>Since Each gpu adapter might have one to two display connected, I can't use the display number.</p>
  
  <p>I'm utilizing Direct3D10. I don't mind solution in Direct3D9.</p>
  
  <p>Worse case would be to let user select display and adapter via commandline, but I prefer a fool prove method.</p>
  
  <p>Thanks</p>
