I have been using displayfusion for a few years now and its worked fine but yesterday i started getting this error when trying to switch monitor profiles:

"An error has occurred while applying your new Monitor configuration. Please check your settings and try again. Error: Failed to call SetDisplayConfig. [HR: 87]"

Only thing i can think off that might be setting it off is either the new beta build (rolling back doesnt fix it) or a new display driver.

EDIT: Seems to have something to do with the 3rd monitor. All profiles without this one seems to work. I can manually start it through CCC which is weird.

Enabling it through Windows Screen Resolution works fine but i need to restart the monitor after a failed profile switch. Tried to manually redo all the profiles with no effect. Im starting to wonder if it has something to do with the new amd beta drivers.

anyone ever find a solution to this? i seem to be having the same problem. it's not AMD beta drivers, i'm using the stable release. i'm currently running DF beta 10 (downgrading from 11 didnt help), start8, modernmix. was using windowfx which i uninstalled but that didn't help the issue. i'll try uninstalling all the stardock apps and report

it is almost certainly an issue with a 3rd monitor connected. physically unplugging the 3rd monitor made the issue disappear.

I have a sapphire r9 290.For me the problem seems to be that when i activate a profile with the monitor that DF calls 3 which i connected to my 2nd DVI port i wont work. I can however activate it through windows own manager but sometimes i need to restart the monitor to make windows find it correctly. Then it will work fine. I can switch from to a profile using the 3rd monitor to the one on the other dvi (2) or/and my tv (1). But trying to switch back breaks it. Tried uninstalling Amd control center but no dice. Gonna try a full reset of DF aswell

As i said before this just randomly started happening.

EDIT: Full reinstall did not fix this for me.

might not even be an issue with DF but with ATI drivers or the cards themselves. i'm running a 7970 and R9 280X in crossfire (same cards pretty much). not sure whats going on but now just plugging in the hdmi cuts off the two displayport monitors. my monitors are 2160p, 1440p, and 1080p. who knows.

very shortly i will have a second GPU installed. since it wont be crossfired (it's staying in for folding@home) i'll just connect my 3rd monitor to that one. once i do that i'll report back with my findings. obviously getting a 2nd video card isnt a great option for most users, but maybe i can shed some more light on the problem if nothing else. i seem to be able to reproduce the issue even with DF uninstalled, so it's certainly a driver or hardware issue.

on another, possibly related note, i've had installation of the newest drivers fail on me several times. every time it went to detect the displays it would crash and install would fail. once it even BSOD and restarted on me. eventually just installed in safe mode with one monitor plugged in.

I've started having the exact same problem with my third monitor after updating my AMD drivers today. Was a fix ever found?

Hi I recieved the same error "Failed to call SetDisplayConfig. [HR: 87]". I have one monitor 2560x1080 21:9 @ 60Hz and the second is 1920x1080 16:9 @ 120Hz. When I change it from the ultrawide to fast monitor I recieved the error. Please help.

I tried both, hotkey and panel from taskbar. It only give me the error if I go from 21:9@60hz to 16:9@120hz. In oposite direction is ok (hotkey and panel).

I resaved the profile, tried to switch via "DisplayFusion Monitor Configuration" and it worked. But after restart it is same. I must switch it via Nvidia panel to the 120Hz monitor. When I to switched back to 21:9@60hz monitor it switch but shows me the same error. And after it want switch back via shortcut or DisplayFusion Monitor Configuration.

Have received this message today when switching between profiles. Laptop running Intel graphics, second monitor is usb powered (AOC brand). Also have had issues with the windows task bar not auto hiding and DF not opening when clicking the task bar button. Can't change it in MM either.
Let me add originally using hotkeys - when first set up switched to profile for extending monitor, but got this error message when trying the hotkey to go back to clone profile.

This is even worse. After that I see 2 more displays in display panel. And they have uncorrect resolution. After few try to switch active display desktop stop responding and I need to restart PC. I will change the displays manualy it would be faster than type here

I am having the same issue now after the last update yesterday 05/24/2018.

The update ran while I was connected to the computer using TeamViewer.

For me, 9.2.2 created the problem.

I've been using DisplayFusion for years on VirtualBox headless VMs accessed via Remote Desktop. These are Windows 10 Pro (version 1803) guests running on Windows 10 hosts with the same OS. Display Fusion has always worked just fine. Yesterday I ran the update to 9.2.2. and it broke. If I run the VM in standard (not headless) mode, DisplayFusion works fine. But under remote desktop, Wallpaper profiles stopped working. All options on the Desktop Wallpaper settings app are greyed out. The taskbar manager still seems to work OK.

My Virtualbox VM is configured for one screen, and I have the remote desktop connection configured to span across all monitors. The VMs are running the Oracle VirtualBox Display Driver.

I've attached a screen capture of what I'm seeing.

Here you go.

Just thought I would chime in to say that I am having the same issue since 9.2.1 using Nvidia. I don't really have much more to add though unfortunately. It happens with hotkeys and manually switching profiles, and the only way I have found to fix it is to enable all three monitors through windows first.

Yeah, problem persists in 9.2.2

I just installed the 9.2.4 (beta 1) released on June 1 and my problem appears to have been fixed. Thanks!

Hello, I've had that problem for a a few month now.
I have 3 screens plugged on my graphic card : 2 monitors and a TV. I use hotkeys to switch setups. If I turn the computer with the TV off and turn it on later, I have that error. I can for force the detection with Nvidia control pannel but then the TV sound output is not detected.
The only fix I have found is to reboot the computer with the TV on.

I've tried reinstalling Display Fusion and Windows 10 but nothing worked. I have the latest version of Display Fusion through Steam.

Thank you for the answer. I'll keep searching for the source of the problem.
