[Windows 10; DisplayFusion Pro 9.6.1 purchased via Steam] I have two monitors connected to a GTX1060-3GB: Dell Alienware AW3418DW 34-inch Ultrawide and Dell U2412M 24-inch. DisplayFusion has managed the setup fine, but today I tried to setup separate monitor profiles for 2 monitors and another for just the Alienware (with the Dell U2412M disabled) and assign each to a hotkey combination. I set up both profiles and switched between them within the Monitor Profiles window without issue. However, when I tried the hotkey to switch to the dual monitor profile, I got this error:



Please advise. Thanks!

[Sorry for taking so long to get back to you]
As a matter of fact, when I try to switch monitor profiles back from single monitor to dual monitor, I get the identical error from DisplayFusion:



I'd be interested in any ideas you have for a fix. Thanks!

Thank you, Keith! I knew you guys would be on top of it. Let me know if you need logs.

Thanks, Keith! I bought DisplayFusion through the Steam store, so I'm not sure how to install the beta in the location where Steam keeps DisplayFusion. There doesn't seem to be an option to install a beta through the Steam interface. Please advise. Thanks!

Open up your settings panel.

Hi
I have updated to 9.7 Beta 5 and now i have the problem:

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]

is there a way to fixit?
I am running one philip ultrawide 49" monitor where i split the screen into areas.

Hi
Sorry for the late response, I have not had access to my workspace before now, due to covid

Thanks for your answer, I deleted the monitor profiles and created them again, at now it seems to work perfect..

Hi,

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?

The monitor is enabled when I go to the Montior Configuration. Right now, I'm typing this while viewing the attached monitor, however, the splits aren't working and if I try to load the profile it gives this:

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]

I've attached the log file.

I think it disables the laptop screen (or maybe that's automatic). 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.

Hi,
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

I've added the log as attachement

Is there a fix for this error? Ever since I purchased DisplayFusion, I haven't been able to get this to work. I created a monitor profile for home and one for work, and when I click Load Profile and choose one, I always get the HR: 31 error.

Here you go!

I have different monitors at work than what I have at home. 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.

Here are the files before and after getting the error.

So, I tried it both at work and at home, and it's working fine now. I'm not sure what changed, but all is good. Thanks for your help!
