I forgot to mention that when running on Linux (displaying back on Windows), the Python 3 version (3.6.4, Tk 8.6) does cover all three screens. The Windows Python 2.7.14 version with Tk 8.5 has problems.
Try to upgrade to 2.7.15. It should be shipped with Tk 8.6. -- https://mail.python.org/mailman/listinfo/python-list
