Windows 10: How to disconnect a non-existing monitor?

For some reason, Windows determines that there are 2 monitors connected to the system, even though there is physically only 1. When installing updates, it makes this non-existent monitor the main one and opens all the windows on it, each time I have to perform a hack with moving setting window to be able to switch to “Display duplication” mode. 1. Are there ways to tell Windows that the second monitor does not exist? the “turn off monitor” option for this particular non-existent one is not in the menu. I can see this option for existing monitors only 2. Is there a way to set a real monitor a

Windows 10 multiple non-existent screens

Ernie - trouble shooting is listed in original post - but just to be sure - here is what I have tried:

1. in Advanced display settings, select one of the non-existent screens, select Disconnect this display in the Multiple Displays drop down - however the Apply button always remains greyed out so you can never complete the disconnect action.

2. Open Device Manager and list the Monitors. It shows 5 monitors listed - 4 of them are listed as Generic non-PNP. If I delete all these monitors, Display Settings still shows the multiple non-existent screens and after a restart Device Manager is again
populated with the 5 monitors.

3. Open Regedit and search for "display" in HKLM. This lists 5 keys that look like they may be referring to the multiple screens. Deleting all these keys and then checking Display Settings again shows no change - the non-existent screens are still being
shown as present.

4. As the laptop is dual graphics Intel/Nvidia - alternately disable one or other graphics controller. Makes no difference.

5. Install latest display driver from Intel and install. Disable Nvidia. Checking Display Settings still shows the multiple non-existent screens.

Things I have not tried so far:

1. Reverting back to a previous system restore point - there is no convenient restore point recent enough to this problem. Most recent restore point looks like it is from a date where restoring to it will lose me a number of significant changes which for
the moment I am reluctant to do - and no idea if it will make any difference.

2. Backup my data files and restore Windows back to it's original installation state. Bit drastic also...

So - open to other ideas. Seems to me windows must be storing some monitor objects somewhere that it thinks are still valid. How do I find them and remove them?

Thanks
