Product: 15-an044nr - Star Wars Pavilli
Operating System: Microsoft Windows 10 (64-bit)

My HP laptop has an intel HD 520 graphics card with an HDMI out port.  I can use dual monitors when I am in the windows environment.  However, I work from home on a secure desk top (loaded from a thumb drive).  Once the Secure desktop loads, both monitors work, but they only DUPLICATE.  I cannot get them to EXTEND.  The SD has a video toggle, and it does not recognize that I have two monitors.

 

Is there a toggle I can use via software or Bios?  I have a feeling it is because the wireless monitor  capability.  Eventhough I do not wirelessly connect to the monitor, the secure desk top doesn't like anything wirelessly connected.  I can use the external monitor on the secure desk top with an older laptop that has VGA output.  Should I try an HDNI to VGA adapter?

 

As far as BIOS setting go, I am required to enable legacy boot and turn off scure boot for the secure desktop.

 

Any help will be greatly appreciated.  I contacted intel already, and they directed me to HP...
