We've had a few customers note the recent Windows update has caused issues with their monitor profiles, but so they haven't run into any issues since recreating them.

Can you try to recreate them again, and let me know if the issue happens again?

Thanks! ]]> https://www.displayfusion.com/Discussions/View/failed-to-call-setdisplayconfig-hr-31/?ID=cbd9b1a5-fbab-4b46-ba88-0fd076452338#5 Thu, 18 Mar 2021 08:19:19 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/failed-to-call-setdisplayconfig-hr-31/?ID=cbd9b1a5-fbab-4b46-ba88-0fd076452338#5 DisplayFusion Sorry, I didn't see your reply. No changes as I am aware of was made to the system.

Although it broke just know, and Windows had an update. But I must say I havn't been using it the last week so can't be sure the update is what caused it. ]]> https://www.displayfusion.com/Discussions/View/failed-to-call-setdisplayconfig-hr-31/?ID=cbd9b1a5-fbab-4b46-ba88-0fd076452338#4 Fri, 26 Feb 2021 19:42:30 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/failed-to-call-setdisplayconfig-hr-31/?ID=cbd9b1a5-fbab-4b46-ba88-0fd076452338#4 DisplayFusion Hi Michael,

Are there any changes to your system when the errors happen, or is it random?

I don't think so. I'm running 9.7.1 on Steam, and I havn't updated since I installed it from Steam. ]]> https://www.displayfusion.com/Discussions/View/failed-to-call-setdisplayconfig-hr-31/?ID=cbd9b1a5-fbab-4b46-ba88-0fd076452338#2 Thu, 25 Feb 2021 20:35:21 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/failed-to-call-setdisplayconfig-hr-31/?ID=cbd9b1a5-fbab-4b46-ba88-0fd076452338#2 DisplayFusion Hi Michael,

Do the profiles fail after a Display Fusion update?

I got one monitor (34" 3440x1440px)

When I create new monitor configurations and save them as profiles with shortcuts, it works fine. But after a while they fail with the below message. Then I have to delete dem and add them again. Its pretty annoying. Any ideas?
