  private DriverBuilder {
    // Option 1
    Dimension dimension = new Dimension(driver.manage().window().getSize().getWidth() * 2, driver.manage().window().getSize().getHeight() * 2);
    driver.manage().window().setSize(dimension);
    // Option 2
    Toolkit toolkit = Toolkit.getDefaultToolkit();
    Dimension screenResolution = new Dimension((int)
    toolkit.getScreenSize().getWidth(), (int)
    toolkit.getScreenSize().getHeight());
    driver.manage().window().setSize(screenResolution);
    // Option 3
    driver.manage().window().setPosition(new Point(0,0));
    java.awt.Dimension screenSize = java.awt.Toolkit.getDefaultToolkit().getScreenSize();
    Dimension dim = new Dimension((int) screenSize.getWidth(), (int) screenSize.getHeight());
    driver.manage().window().setSize(dim);
  }
}

driver.manage().window().fullscreen(); also might work though ))
