Custom Monitor Resolution not recognized by Java
- by Angie
My weird monitor's native resolution isn't recognized by Windows, so I have to set a custom resolution for it. The problem is that java doesn't recognize it since it's not on Win7's "approved" list, so full-screen mode gets "stuck". Netbeans comes out of full-screen fine, so there has to be a way around this. Anyone know it?
This example reproduces the issue:
package resolutionexample;
import java.awt.Dimension;
import java.awt.DisplayMode;
import java.awt.GraphicsDevice;
import java.awt.GraphicsEnvironment;
import javax.swing.JFrame;
import javax.swing.SwingUtilities;
public class Main {
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable(){
public void run() {
GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice gd = ge.getDefaultScreenDevice();
DisplayMode currentDM = gd.getDisplayMode();
boolean currentInAvailable = false;
System.out.println("Available resolutions:");
for ( DisplayMode availDM : gd.getDisplayModes() ){
//System.out.println(availDM.getWidth() + "x" + availDM.getHeight());
if ( availDM.equals(currentDM) ){
currentInAvailable = true;
}
}
System.out.println("Current resolution: " + currentDM.getWidth() + "x" + currentDM.getHeight() );
System.out.println("Current in available: " + currentInAvailable);
JFrame frame = new JFrame("Resolution Bug Example");
frame.setVisible(true);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
if ( !gd.isFullScreenSupported() ){System.exit(0);}
gd.setFullScreenWindow(frame);
gd.setFullScreenWindow(null);
}
});
}
}
Output running 1680x1050 (the monitor's wonky native resolution):
run:
Available resolutions:
Current resolution: 1680x1050
Current in available: false
