Optimizing java for multiple screens and resolutions

Question

Hello I am creating a 2D RPG game in my free time and I have been mostly working on it from my laptop but when I brought it to school to work on it it crashes and gives me the error in the eclipse console:

org.newdawn.slick.SlickException: Failed to find value mode: 1366x768 fs=true
          at org.newdawn.slick.AppGameContainer.setDisplayMode(AppGameContainer.java:146)
          at com.states.Core.main(Core.java:49)

The resolution i have been using is WIDTH = 1366, HEIGHT = 768 please let me know if there are better ones and thank you to the ones that can help

This bit of code will give you the usable screen width and height on any system.

import java.awt.GraphicsEnvironment;
import java.awt.Rectangle;

public class ScreenResolution {

    public static void main(String[] args) {
        Rectangle r = GraphicsEnvironment.getLocalGraphicsEnvironment()
                .getMaximumWindowBounds();
        System.out.println(r);
    }

}

On my system the result is:

java.awt.Rectangle[x=0,y=0,width=1280,height=984]

The GraphicsEnvironment class gives you information about fonts and screen devices.
