Welcome Kerry,
Thank you for describing the issue in details, you provided enough information to diagnose this.
I believe you are hitting a limitation of the primary graphics card driver we have
documented in our FAQ.
I would first advise to seek a "Windows 10 Anniversary Update graphics driver" from your graphics card vendor. If not available, you may wish to either remove their driver to use the default Windows driver which supports cloning across graphics card, however there is a cost in performance. Some third party tools also allow doing this.
Kind regards,
Alban
