Only see extended monitor on both monitors

[amarone]

After various issues following installation of Windows 10AE, I am now in a mode where the display appears to have extended the screen across two monitors (I want them duplicated, not extended) and both monitors display the right half. No applications load in the right half so I cannot do anything. If I start the Windows display configuration application to change how the monitors display, it loads in the left half so I cannot get to it.

If I disconnect the second monitor, then I can see the config app (and everything else), but it does not give me any options for controlling the dual monitor setup because there is no dual monitor at that point.

How can I get to the left half of the screen? Or force the display config app to load in the right half?

Hello,

Would you please be able to post the logs with a photo of your monitors showing the problem so I can better understand the phenomenon?
