    Intel® HD Graphics 4600 3rd screen access?


      Trying to get access to the third screen this card is suppose to support.  per this link https://www.intel.com/content/www/us/en/support/articles/000025673/graphics-drivers.html.  I have installed a Stardock DisplayPort Triple-Video Docking Station for Laptops - USB 3.0 | Laptop Docking Stations | StarTech.com  This device connects through a USB 3.0 port, and have tried 2 such ports of this HP HP ENVY TS m7 Notebook PC laptop.  This is a 64 bit windows 8.1 system running a i7-4700MQ CPU @ 2.40GHz. intel CPU,  Graphic image confirmation the software is properly installed=  2018-06-08_2018   2018-06-08_2036


      The graphics card driver version installed for the 4600 card is and shows to be the most current per Intel® Driver & Support Assistant and shows to be "This device is working properly". Graphic image confirmation 2018-06-10_1339 . and confirmed by the attachment file.


      I have been able to produce the 2nd or Projected screen through the HDMI port of this Stardock DisplayLink device, but have not been able produce a third screen through the same HDMI port.  Windows Display Setting does not seem to be able see a 3rd screen. 


      Before trying this Stardock type external graphics card is supposed to be able to produce triple screen adapter card, I have earlier produced a 3rd screen via a SIIG (3J) external graphics adapter card.  Yes the two graphics adapter systems are incompatible, and the 3J (MCT Trigger External Graphs code) code has been uninstalled.


      If the proper graphic card settings are resolved do you see any reason why these extra 3 screen production cannot be possible?
