Hi, I've been working on a Slick2D game for a while now and have recently tried to see what it would look like played on full screen mode, I get an error message and I havn't been able to fix it, any help is apprieictated.

public static void main(String[] args) throws LWJGLException {

      AppGameContainer appgc;
      try {
         appgc = new AppGameContainer(new Game(NAME));
//          appgc.setFullscreen(true);
        appgc.setDisplayMode(1200, 800, true);//This is line 70 and the game runs fine with this Boolean set to false
        appgc.setIcon("res/image/f.png");
         appgc.setShowFPS(true);
         appgc.setTargetFrameRate(60);
         appgc.setVSync(true);
         appgc.start();
      } catch (SlickException e) {
         e.printStackTrace();
      }

Tue Jul 03 20:28:33 CDT 2012 INFO:Slick Build #274
org.newdawn.slick.SlickException: Failed to find value mode: 1200x800 fs=true
   at org.newdawn.slick.AppGameContainer.setDisplayMode(AppGameContainer.java:146)
   at game.Game.main(Game.java:70)


In regards to the error message, clikcing on "AppGameContainer.java:146 links me to the class but I get the message "146 is not a valid line number in org.newdawn.slick.AppGameContainer."

Perhaps 1200x800 screen size/ratio isn't supported in full screen mode?

Iterate over the available display modes, and pick one. Then you'll be sure the resolution you specified will be supported.

How do I iterate over the available display modes?

         DisplayMode[] modes = Display.getAvailableDisplayModes();

         for (int i=0;i<modes.length;i++) {
             DisplayMode current = modes[i];
             System.out.println(current.getWidth() + "x" + current.getHeight() + "x" +
                                 current.getBitsPerPixel() + " " + current.getFrequency() + "Hz");
         }
         System.out.println(appgc.getAspectRatio());

I changed 1200x800 to fit the ratios of some of those numbers but I still get the same error.

Pass the exact width and height of a supported display mode.
