Windows 10: Windows 10 Monitor 1 and 2 are not showing in Display

I want to add a 2nd monitor to my son's PC and when I got to display to extend from 1 to 2 monitors, NEITHER monitor boxes are showing. Detect doesn't find either of them. My son is currently using Monitor 1 to play his game but I wanted to add the other monitor and I can. Graphics card is up to 4 monitors, so all good there. What do I need to do to get Monitor 1 and Monitor 2 to show in Display? Pls help as I cannot find any support on any other channels

:)

 

2 Monitor Display - Display 1 stuck on wrong monitor

I have a 2-monitor setup. As recently as yesterday (1/20/2020), the display settings had Display 1 on the left monitor (main display) and Display 2 on the right monitor. Today, Display 1 is on the right monitor regardless of how I configure the display settings.

In the top screenshot, in the image below, Display 1 is on the right and Display 2 is on the left in the display settings. This is consistent with the layout that 'Identify' ... identifies. In the bottom screenshot, the display settings show Display 1 on
the left and Display 2 on the right, however 'Identify' shows Display 1 on the right and Display 2 on the left.





For what it is worth, these screenshots are edited to be consistent with my monitor setup. When the display settings show Display 1 on the left and Display 2 on the right, both the cursor and a raw screenshot behave as if that is true.
However, Display 1 is stuck on the right monitor, so these screenshots show what I am seeing.

I have tried unplugging and re-plugging the monitors, uninstalling and re-installing the display drivers, and rebooting the computer. Nothing satisfactorily resolves my problem, which is that regardless of the display settings, Display 1 is stuck on the
right monitor. I could make Display 2 my main display and have that be on the left, which would
functionally make the setup do what I want, but would not resolve the actual problem of Display 1 being stuck on the right monitor. Since the displays were set how I wanted them yesterday, clearly something has changed, and I'd like to know what.
