You can run java as a full-screen application, for example, exclusive mode.
DisplayMode oldDisplayMode = myDevice.getDisplayMode();
try {
myDevice.setFullScreenWindow(myWindow);
myDevice.setDisplayMode(newDisplayMode);
...
} finally {
myDevice.setDisplayMode(oldDisplayMode);
myDevice.setFullScreenWindow(null);
}
You can also change the display mode. If your device supports Vesa modes, it may be on the list of available modes in Java.
