Thank you for contacting Intel Communities.
In this case, I would recommend installing the latest graphics driver:
Intel® Graphics Driver for Windows* [15.40] Version: 184.108.40.20624 (Latest) Date: 3/30/2017
And also to have the latest BIOS (in case you have an older version):
BIOS Update [RYBDWi35.86A] Version: 0362 (Latest) Date: 1/18/2017
In addition, please check this article regarding setting up multiple displays.
Please let me know how it goes.
