I have an Inspiron 3671 desktop, running Windows 10, with two P2219H monitors in my home. My original set-up had an HDMI cable running from one monitor and a VGA cable running from the other monitor.  When my wife or I log in remotely to our respective office workstations, located elsewhere, using Windows' Remote Desktop Connection or using GoToMyPC we are unable to drag objects (web pages, spreadsheets, documents, etc.) on the remotely-connected workstation's screen from our primary monitor to our second monitor.  Is that even possible?  To try to remedy this I got an HDMI splitter, ran HDMI cables from both monitors to the splitter, then from the splitter to the Inspiron's HDMI port, but ended up with two identical monitor displays. When I go into the display settings it does not detect a second monitor, nor will it allow me to "Extend" the displays in the Multiple Display settings.  Those options are disabled.  Is what I'm trying to accomplish possible when connecting remotely?  Recommendations will be appreciated.  Thank you.
