    GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
    GraphicsDevice[] gs = ge.getScreenDevices();
    for (int i = 0; i < gs.length; i++) {
      VolatileImage im = gs[i].getDefaultConfiguration()
          .createCompatibleVolatileImage(1, 1);
      int bytes = gs[i].getAvailableAcceleratedMemory();
      if (bytes < 0) {
        System.out.println("Amount of memory is unlimited");
      }

      im.flush();
    }
