    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!

    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.
