Thank you again. ]]> https://www.displayfusion.com/Discussions/View/unable-to-change-monitor-profiles-in-971-beta-3-among-other-versions/?ID=18c7f14b-185f-490e-b842-8dab5c2ec708#8 Fri, 21 Aug 2020 15:56:21 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/unable-to-change-monitor-profiles-in-971-beta-3-among-other-versions/?ID=18c7f14b-185f-490e-b842-8dab5c2ec708#8 DisplayFusion @Troy: That makes sense. DisplayFusion isn't able to toggle Surround mode itself, so the extra step of disabling/enabling it first is needed.

@Phillip: If you re-save the monitor profile, does that make any difference? We've had a few other customers on beta 4 that still received the error 31 error, but after re-saving their monitor profiles they're working again. ]]> https://www.displayfusion.com/Discussions/View/unable-to-change-monitor-profiles-in-971-beta-3-among-other-versions/?ID=18c7f14b-185f-490e-b842-8dab5c2ec708#7 Thu, 20 Aug 2020 14:53:24 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/unable-to-change-monitor-profiles-in-971-beta-3-among-other-versions/?ID=18c7f14b-185f-490e-b842-8dab5c2ec708#7 DisplayFusion What I am able to do is use the shortcut key for Nvidia surround, once it's on, then I use the shortcut key for DF to switch to setup. Once I am done, I use the nvidia shortcut again to turn it off, then use the shortcut for DF to put my screens back the way I had them and I don't get the error. Seems like I only get the error when I try to use DF shortcut to go to Nvidia surround before it is active. ]]> https://www.displayfusion.com/Discussions/View/unable-to-change-monitor-profiles-in-971-beta-3-among-other-versions/?ID=18c7f14b-185f-490e-b842-8dab5c2ec708#6 Thu, 20 Aug 2020 14:29:59 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/unable-to-change-monitor-profiles-in-971-beta-3-among-other-versions/?ID=18c7f14b-185f-490e-b842-8dab5c2ec708#6 DisplayFusion Here you go.

After restarting the machine (and before as well), I got the following 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]

Unfortunately, that is the same error. Any ideas? ]]> https://www.displayfusion.com/Discussions/View/unable-to-change-monitor-profiles-in-971-beta-3-among-other-versions/?ID=18c7f14b-185f-490e-b842-8dab5c2ec708#3 Tue, 18 Aug 2020 21:05:50 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/unable-to-change-monitor-profiles-in-971-beta-3-among-other-versions/?ID=18c7f14b-185f-490e-b842-8dab5c2ec708#3 DisplayFusion Same issue here, I get the same error code and everything. Used to work, but no go now. ]]> https://www.displayfusion.com/Discussions/View/unable-to-change-monitor-profiles-in-971-beta-3-among-other-versions/?ID=18c7f14b-185f-490e-b842-8dab5c2ec708#2 Tue, 18 Aug 2020 17:49:35 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/unable-to-change-monitor-profiles-in-971-beta-3-among-other-versions/?ID=18c7f14b-185f-490e-b842-8dab5c2ec708#2 DisplayFusion Hi Phillip,

We have some monitor config fixes coming out in our next beta. We'll let you know when it's released so you can give it a shot and see if it fixes your issue.

Thanks! ]]> https://www.displayfusion.com/Discussions/View/unable-to-change-monitor-profiles-in-971-beta-3-among-other-versions/?ID=18c7f14b-185f-490e-b842-8dab5c2ec708 Sat, 15 Aug 2020 15:30:47 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/unable-to-change-monitor-profiles-in-971-beta-3-among-other-versions/?ID=18c7f14b-185f-490e-b842-8dab5c2ec708 DisplayFusion I have been unable to change monitor configurations since at least 9.6. It does not work with hotkeys or with manually selecting the setting in Monitor Configuration. I get the following 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]"

The only way I can change the configuration is by manually deleting/editing the current monitor configuration.

I have updated the program multiple times to versions (both release and beta) that seemed to fix the issue for others. I also tried changing the Disable Application Hooks setting in Advanced Settings as was suggested. That didn't work either.

Any help would be appreciated. ]]>
