How to change display mode with Java Swings

To change display mode with Java Swings, use the setDisplayMode() method. Here, we have set the Display mode as:

new DisplayMode(800, 600, 32, 60));

Now, when you will run the program, the frame would be visible in a different resolution than the actual set resolution of your system.

The following is an example to change display mode with Java Swings:

Example

import java.awt.DisplayMode;
import java.awt.GraphicsDevice;
import java.awt.GraphicsEnvironment;
import javax.swing.JFrame;
public class SwingDemo {
   public static void main(String[] args) {
      JFrame frame = new JFrame();
      frame.setSize(800, 600);
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      GraphicsDevice graphics = GraphicsEnvironment.getLocalGraphicsEnvironment()
         .getDefaultScreenDevice();
      graphics.setFullScreenWindow(frame);
      graphics.setDisplayMode(new DisplayMode(800, 600, 32, 60));
      frame.setVisible(true);
   }
}

The output is as follows displaying a new display mode. Current mode of the system is 1366x768 and we have set 800x600 for the frame:
