You can use the "Monitor Configuration: Force Primary Monitor ID" option in the DisplayFusion Settings > Advanced Settings to do this. Set it to 1.2, apply the settings, then restart DisplayFusion and you should be all set.
I see that this featuer has not made it to the current version; any reason why? This was posted by someone else a year ago, would be great to be able to force primary split monitor so the single taskbar shows up where I want it, multi taskbar does not solve anything for me except confuse and repeats itself.
I've got the exact same monitor setup as Wallis and it's not letting me Force Primary Monitor ID to 1.1. The middle one is primary no matter what number I put in
edit: Made another profile to test, 21:9 on monitor 1.2. I tried with default values and 1.1 as Primary Monitor ID. Windows 11 did not care either way and defaulted the primary monitor to 1.2. It seems to always pick the larger split.
I've reverted some setting I had when I made the post so let me know if you need me to change anything back.
I guess I'll explain my use case for this. I want the primary 'monitor' to be have a displayfusion taskbar so that I can disable it while playing borderless fullscreen games. I'm having to autohide the taskbar since the largest 'monitor' will automatically become the primary and it's become annoying accidentally showing the taskbar and clicking out it, making me lose focus.
This issue should be fixed up in the latest beta, available here: https://www.displayfusion.com/Download/Beta. Please let me know if you still run into any trouble after updating. You'll also want to use the "Windows Taskbar Split Monitor ID" advanced setting as well.
