title: OpenCV Python: Play video FULLSCREEN on second monitor with Python?
body: <p>I'm using my Macbook (first monitor) to create an experimental set-up for a CRT monitor (second monitor).</p>
  
  <p>This function displays the window on my first monitor.</p>
  
  <pre><code>def play_vid(vid_filename):
      cap = cv2.VideoCapture(path_to_vid + vid_filename )
      if (cap.isOpened()== False): 
          print("Error opening video stream or file")
      else:
      while(cap.isOpened()):
        # Capture frame-by-frame
          ret, frame = cap.read()
          if ret == True: 
              capname = "cap"
              cv2.namedWindow(capname, cv2.WND_PROP_FULLSCREEN)
              cv2.setWindowProperty(capname, cv2.WND_PROP_FULLSCREEN, cv2.WINDOW_FULLSCREEN)
              cv2.imshow(capname, frame)
              cv2.waitKeyEx(40)
          else: 
              break    
  </code></pre>
  
  <p>Is it possible to use cv2 to display the window on a second monitor fullscreen?</p>
