Windows 10: Multiple Monitor issue with KVM

My config:

I have a personal laptop and a work laptop. I use the built in LCD screens on the laptops as the main screen for each.

I also have an external monitor that I share between the two laptops with a KVM switch. So, whichever computer is selected by the KVM has the external monitor as a secondary display.

I have happily used this configuration for months.

Recently, I upgraded the personal laptop from Win7 to Win10. The work laptop is still Win7.

Now, when I KVM from my personal laptop to the work laptop, everything that was being displayed on the external screen for the personal laptop is transferred to the main screen of the personal laptop. This means that when I switch back to the personal laptop I have to move the programs I want displayed on the external monitor back to the external monitor. It still works properly on the work laptop (Win7), so I am concluding that the issue is Win10. Is there some setting that I can change so that when I switch from the personal laptop to the work laptop it doesn't move the programs displayed on the extended monitor back to the main display?

Thanks for any help!

Microsoft can you please, for the LOVE OF GOD, put in an option to disable automatic monitor detection in Windows 7 and up?

Have you thought about using a KVM switch in your setup?

That might alleviate the detection as the KVM switch should report to all your systems that there's a monitor there even if there isn't (switched away) at that particular moment.

Another option is to setup one computer as the "master" and then the other computers as headless and remote desktop into them.

I've done both types of setups over the years with multiple monitors and never had an issue.

After the upgrade to Windows 10, the graphics driver was replaced by generic Microsoft driver that doesn't support the external port. Download latest graphics driver from manufacturer's site and install it. You can then select the external monitor either by your notebooks's key combination or from Window's universal Win+P.
