Error: Failed to call SetDisplayConfig. [HR: 87]

Hi,

I get the error message "Error: Failed to call SetDisplayConfig. [HR: 87]" most of the times (bot not always) when I try to switch to a monitor profile which enables my TV connected via HDMI. The only thing that helps if it occurs is enabling the TV manually in the Nvidia control panel. This happened both with my old GTX 970 as with my new RTX 2060S. I have attached a log.

Cheers,
Gian

Could you try rolling back to DisplayFusion 9.5, create a new profile there, then load it and see if it errors out as well?

So far, that version seems to work just fine; it either tells me my TV is disconnected when its powered off or changes to the desired profile when its powered on whereas 9.6+ would always show HR: 87 when its powered off.

Ok, thanks! We're working on some more fixes for the Monitor Config in the next beta, so we'll let you know as soon as it's available to try out. In the meantime, feel free to stick with 9.5 if it's working well.

We've just released a new DisplayFusion Beta version and the Error 87 issue should hopefully be fixed up.

Could you try updating, and if your profiles still throw an Error 87 when trying to load them, try re-saving the profiles?

Please let me know how it works out

I have the same problem in a 3-display setup. I have tried 9.7 beta 8 and 9.6.1. Both don't work. Where can I get the old 9.5 version to test whether it works with the old version?

It would seem I have a similar issue. I have a monitor and a tv hooked up and if I try to enable both in mirror mode 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: 87,0]
[System.Exception]

If I don't mirror it works ok.

Running DisplayFusion 9.7 (Beta 10) on Windows 10.

@Eric: If you set it to duplicate in the Windows display settings, does it work there?

Hi, yes it works fine via the Windows settings.

For what it's worth, I setup mirroring in Windows, went back to Display Fusion and it shows the correct mirroring setting however if I try to apply any changes I get the same 87 error.

My setup has my main pc monitor hooked up to my GTX2070 and my tv to my onboard hdmi. Which has previously worked.

Ok, interesting! If you configure it using the Windows display settings, then save it as a profile in DisplayFusion, do you still get the Error 87 when you try to load it?

Ok, did anything notable happen around the time it broke? e.g. did any of the cables get swapped, or video card drivers update maybe?

Could you also do a test for me? If you try loading it with the Load Profile button in the Monitor Configuration window, instead of using the hotkey, does it fail there too?

Not sure if anything specific happened - perhaps some updates but I don't know.I tried some testing and it appears the error only presents when I try to mirror. See attached PDF with screenshots. I am able to enable both the monitor an TV via the Display Fusion UI but as soon as I try to mirror it fails. I can enable mirroring via the windows display settings without issue.

Ok, would you be able to send me some info?

A debug log:
  • On the DisplayFusion Settings > Troubleshooting tab, change the Logging drop-down to "L1: Log Minimal" and click Apply
  • Try loading the profile
  • Click the "Export Info to File" button on the Settings > Troubleshooting tab
  • Reply with the file attached
  • Disable debug logging after sending the log

Two copies of the info from this tool: https://www.binaryfortress.com/Files/DisplayFusion/BFCustomerTest20200429.zip
  • One copy after trying to load the profile (close the tool after grabbing the info)
  • Another copy after enabling the cloning using the Windows display settings

Thanks!

Any updates on this? I am running into the same issue. I have a profile set-up for the mirroring of two tv screens (four screens plugged in, the other two screens not active). It used to work fine but is now giving me the:
"An error has occurred while applying your new Monitor configuration.
Please check your settings and try again.
Error: Failed to call SetDisplayConfig. [HR: 87]
[System.Exception]" error. It works correctly when I use the normal windows option to mirror the screens, and then DisplayFusion (DF) also automatically recognizes that the profile is active. I also think the DF profile switch works when I have both TV's on and have not rebooted after I have had the profile active (but I would have to do more testing to be sure). Not sure if related, but just before this started I updated my NVIDIA drivers to: "431.60-desktop-win10-64bit-international-whql" and I am still running into the issues with my current most up to date driver: "446.14-desktop-win10-64bit-international-dch-whql". It is also around the same time that I started using the Xbox BETA app which is also causing the random focus changing when having the Xbox app + DF taskbars combination:"https://www.displayfusion.com/Discussions/View/window-focus-unexpectedly-changing-to-another-app-while-typing/?ID=e5fc9266-dc54-4ada-b6fd-440379ac2932". I am using DisplayFusion Pro on Steam V9.6.1. Please let me know if I can help with gatering / giving more information to get this issue resolved?

@BTA: Could you try updating to the latest 9.7 Beta, re-create the profile, and then see if it loads correctly?

@Eric: Thanks for sending that info, I will pass it over to our developers and we'll keep you posted on what we find out.
