I haven't found a way to do so with Display Fusion, so I'm having to use a separate utility for this particular feature (Helios Display Manager which is able to toggle nVidia Surround on/off as expected). Would be great if this was supported by DisplayFusion.
Thanks! ]]> https://www.displayfusion.com/Discussions/View/error-failed-to-call-setdisplayconfig-hr-31-systemexception/?ID=2228253d-5f5b-431d-9dc3-cca7dc496841#2 Tue, 30 Mar 2021 15:38:36 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/error-failed-to-call-setdisplayconfig-hr-31-systemexception/?ID=2228253d-5f5b-431d-9dc3-cca7dc496841#2 DisplayFusion Hi Robert,

We currently don't supporting switching in/out of surround between monitor profiles which is why you're seeing that error, but we do have this open as a feature request. I've added your vote to it, so we'll be sure to let you know if we have any news on it in the future.

Thanks! ]]> https://www.displayfusion.com/Discussions/View/error-failed-to-call-setdisplayconfig-hr-31-systemexception/?ID=2228253d-5f5b-431d-9dc3-cca7dc496841 Tue, 30 Mar 2021 12:37:45 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/error-failed-to-call-setdisplayconfig-hr-31-systemexception/?ID=2228253d-5f5b-431d-9dc3-cca7dc496841 DisplayFusion Hello - I just purchased DF Pro, and trying to switch between 2 different Monitor profiles causes this error:
An error has occurred while applying your new Monitor configuration.
Please check your settings and try again.
Error: Failed to call SetDisplayConfig. [HR: 31]
[System.Exception]

FYI - One config uses 3 monitors separately, the other config uses Nvidia surround to span them as one display.

I also tried the latest beta but still causes the same error - any suggestions?

thanks ]]>
