Enabling Hyper-V on Windows 10 adds new detected displays that do not physically exist : <p>I enabled Hyper-V on my HP Windows 10 Pro laptop today that has a 2nd monitor that is configured as extended display (the laptop is #1, the external monitor is #2).  As soon as I restarted the computer, I noticed that my monitors were now duplicated (showing the same desktop on both monitors).  </p>

<p>When I went into the "Display Settings" screen, I noticed that there were several additional identified displays (3,4,5,6) that do not physically exist.  I could no longer get back to my original display extended display configuration (#1 extended to #2), and could not get my physical monitors to be identified separately.  </p>

<p>The "Multiple Displays" dropdown just showed various options for duplicating the screen across combinations of the 6 identified displays. Trying to manipulate the configuration seem to cause problems, and the system seemed to freeze for a little while, and then revert to the first duplicated configuration.</p>

<p>I tried just stopping the Hyper-v service, but that still didn't remove these "ghost" displays.  </p>

<p>The only way that I got back to a properly configurable display detection was to completed disable Hyper-V.</p>

<p>So any ideas on what caused this?  Are there any Hyper-V settings that can fix this?</p>
