After Windows Upgrade to 1903, I have two not existing monitors connected

The monitors can't be detected (yes pedantic use) if they don't exist. Somewhere something has remembered they existed prior to the reboot. I don't know where the drivers record such info, maybe the registry or a hidden file. Or it's a bug in the drivers.

Thanks, now it works after uninstalling the ghost monitors, the graphics card several times, reboot many times, lost the patience (slamming my fist on the desk) again many many times.
Of course I got several times errors in the Nvidia driver installation program but I started again and again from the beginning.
Then a miracle happened, the trick was (somehow)
- uninstall everything in every possible way known (remove program driver/right clic unistall from device manager).
- Scan for new hardware
- uninstall again the automatically new found hardware (graphic card), even if was not recognised properly (yellow triangle exlamation mark on the device)
- reboot
- install the official nvidia driver, with the option "advanced"-->tick on "perform a clean install"
On C: I have proudly a "windows.old" directory which scares me and eat away space on the hard disk.
Thank you windows upgrade team, please continue like this! Here they are in a recent group pic*:

That's tough, good that you solved it :-+
Not to defend MS but If I just think of all the possible combinations of processors, motherboards, graphic cards and peripherals that should be supported and never all can be tested , I still think it is a small wonder.

If you used the DDU it would be easy to clean install everything. DDU or Display Driver Uninstaller is a app that doesn't need instalation, where you select what is the brand of the video card you use, and it cleans everything, not leaving a trace behind.
Regarding the Windows.old, is the restore files if you want to roll back to the old version of Windows. If everything runs OK after a month, you can remove the folder from the disk without problems using the disk cleanup utility:
LeonR:
I'd suggest using DDU (https://www.guru3d.com/files-details/display-driver-uninstaller-download.html), but it seems you already fixed it.
rrinker:
windows.old is just for undoing the update, if you do;t want to keep using the new version. A very good thing, but once you are satisfied that the new version is good, you can safely remove it and free up the disk space.
Windows 10 is very good at remembering previous monitor setups. This works out very well for me, as I use my laptop in one of three ways. In the office, it's connected to two external monitors, the laptop lid is closed. Out of the office, I am either operating the laptop alone, no extra displays, at 150% magnification so I can actually read things on the screen (14" is too small for 1080, sorry), or I have my USB external plugged in because I can't work productively for long with just a single display. Prior to Windows 10, I was constantly having to rearrange my desktop icons if I scaled the display, or it would put the displays int he wrong order, where moving the mouse to the right woudl start ont he rght-hand screen and then flip to the left hand display, so I would have to go into the display settings and reposition them. This doesn;t happen any more, it comes right up in the settings matching the configuration I am plugged in to.
