title: Python Imaging Library fails to grab whole screen
body: <p>I am using PIL to grab a screen shot, but it is only capturing a part of the screen. </p>
  
  <p><a href="http://i.imgur.com/5s2HtCk.png" rel="noreferrer">Here is a screen shot of my desktop</a></p>
  
  <p><a href="http://i.imgur.com/qNMftgV.png" rel="noreferrer">And this is what the program captures</a></p>
  
  <p>As you can see, the screen has a good amount of space chopped off on the side and along the bottom. I tried to correct this by adjusting the size of the capture zone, but that just resulted in the extra areas just to be filled with black</p>
  
  <p>I'm thinking that there is a limit to the maximum resolution that the library can capture, but I cant really find any documentation saying so.</p>
  
  <p>Below is my code</p>
  
  <pre><code>import ImageGrab
  import os
  import time
  
  
  def screenGrab():
      box = (0, 0, 1920, 1080)
      im = ImageGrab.grab(box)
      im.save(os.getcwd() + '\\screenshot_' + str(int(time.time())) + '.png', 'PNG')
  
  
  def main():
      screenGrab()
  
  if __name__ == '__main__':
      main()
  </code></pre>
  
  <p>Dose anyone know how to fix this issue or know why its happening?</p>
