Could you send me over a debug log? Here are the steps:

• On the DisplayFusion Settings > Troubleshooting tab, change the Logging drop-down to "L1: Log Minimal" and click Apply
• Reproduce the issue and note the time so we'll know where to check in the log file
• Click the "Export Info to File" button on the Settings > Troubleshooting tab
• Reply with the file attached
• Disable debug logging after sending the log

The monitor profiles are just meant to set the splits for the monitors. Every time I switch my work location (home to work or work to home), I have to reset the monitor splits on my secondary monitors. The settings for the primary monitor carry over from work to home and vice versa. At work, I have one external monitor for my primary and two external monitors for my secondaries. The laptop is docked at work, and I don't use the laptop screen. At home, I have one external monitor for my primary and the laptop screen for my secondary, and I don't have a dock. ]]> https://www.displayfusion.com/Discussions/View/displayfusion-961-error-failed-to-call-setdisplayconfig-hr-31-systemexception/?ID=752643de-9736-4883-bdc8-61248082b040#25 Mon, 20 Dec 2021 18:28:32 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/displayfusion-961-error-failed-to-call-setdisplayconfig-hr-31-systemexception/?ID=752643de-9736-4883-bdc8-61248082b040#25 DisplayFusion Thanks for sending that over.

I am also getting this error of late, I was on the latest version and after reading this thread I have updated to the beta branch but am still having the same issue.
I have had a similer issue before but after a reformat of my PC the problem stopped, so re creating the profiles. I have not recreated them yet this time as I have to go to work soon.
I get this error message when i try and fire a profile, either from a shortcut key or via the DF menu. Changing monitors manually through windows display settings works fine. This is happening when I try and change both between seperate physical monitor profiles (one mon on/one mon off), when just changing to a profile that adds/subtracts splits on the same physical monitor or a profile that turns on a second monitor and adds splits to the already connect physical monitor.

As a side note, the dialogue box that appears with this error code, once you click confirm or close the box via the cross it reverts the monitor setup back to the previous profile even if you have already changed the display settings via windows. As one of my monitors is a TV in a seperate room this can become quite annoying if I forgot to close it first. Not the end of the world, and it may be desired by yourselves for some reason but I though I would mention it.

Thanks a lot

Basically, it's so I can dock my laptop when I'm at my desk to an ultrawide. When docked, I want the screen split and when running only on my laptop screen I don't want any screen split. ]]> https://www.displayfusion.com/Discussions/View/displayfusion-961-error-failed-to-call-setdisplayconfig-hr-31-systemexception/?ID=752643de-9736-4883-bdc8-61248082b040#17 Mon, 15 Jun 2020 21:26:28 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/displayfusion-961-error-failed-to-call-setdisplayconfig-hr-31-systemexception/?ID=752643de-9736-4883-bdc8-61248082b040#17 DisplayFusion Thanks! So your profile doesn't change the monitor enabled/disabled state, or resolution, it only changes the split layout? ]]> https://www.displayfusion.com/Discussions/View/displayfusion-961-error-failed-to-call-setdisplayconfig-hr-31-systemexception/?ID=752643de-9736-4883-bdc8-61248082b040#16 Mon, 15 Jun 2020 19:10:05 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/displayfusion-961-error-failed-to-call-setdisplayconfig-hr-31-systemexception/?ID=752643de-9736-4883-bdc8-61248082b040#16 DisplayFusion The monitor is enabled when I go to the Montior Configuration.

I'm having a similar issue. SetDisplayConfig HR:31 and I was on DF 9.6.1. I've checked the "Get beta versions" and am now on DF 9.7 (Beta 19), however, when I go to Monitor Profiles and change to a certain profile, I still get the HR: 31 error.

Now, it may be a compatibility issue with a USB-C Hub. If I connect the monitor directly to my laptop using HDMI everything is fine (and was fine in 9.6.1 also), but I have a USB-C hub that I'm using as a docking station in a way so when I'm at my desk, I plug one USB-C cable in and all my peripherals are connected. Everything works, I see my display over the USB hub, but I get the 31 error when I try to switch to the profile I want.

Any ideas?

It will install over top of the current one and keep the Steam license and settings intact
