Now my monitors match the connections in the back of my graphics card, going from one to three, from left to right. While in Windows, I had the Display page opened, plugged in Monitor 2, then Monitor 3 and they came up and numbered exactly in the order I wanted. I turned off the machine, unplugged everything but what I wanted as Monitor 1, restarted and it booted to Monitor 1. ConnectivityOriginal just to make it easy to revert if needed.) Rather than delete the following entries, I just renamed them: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\GraphicsDrivers\Configuration When I plugged that one in, it would also be seen as Display 2 in Win10.

The monitor I wanted as #1 AFTER my original testing, needed a Displayport to HDMI converter.
#SIDPLAY WINDOWS INSTALL#
After a clean install of Win10, I had a test monitor plugged into plug 2 of my graphics card, since is my HDMI native connection. This procedure was inspired from this pageįor my Win10 desktop, I used the REGEDIT solution above. Proceed to connect what you would like to be monitor 2 (and 3 and so forth) and they should be numbered properly. The monitor will be identified and added as monitor 1 back into the registry. Shut down the machine, connect only the first monitor to the dock (or the machine) and switch the machine on. HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\GraphicsDrivers\Connectivity (Export them and back them up before you delete of course just in case something goes wrong) HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\GraphicsDrivers\Configuration Delete the following entries from the registry.

If you are using a desktop your mileage may vary but disconnect all monitors except #1. If it's a laptop, disconnect it from your dock or disconnect all monitors and use the laptop monitor for the following procedure. The only way I could find to change the monitor identities was the following.
#SIDPLAY WINDOWS WINDOWS 10#
Even if the cables are switched Windows 10 will unfortunately still remember the monitor numbers as it looks like it's using some monitor hardware identifier to attach the identity number.
