Hey there, have been getting this error intermittently when toggling displays:

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]

Weirdly, it only happens sometime, and I haven't been able to identify when. I read through a bunch of other people having this issue and none of them seemed the same, as this is only intermittent. I have four monitors, two profiles, one that disables 3 of them. The second profile re-enables those three and disables the first. It's always that profile that fails probably 30 percent of the time. But, once it fails I have to reboot the PC to get it to work.

I verified that all monitors are recognized by windows, tried turning them off and on again, all that works is a reboot.

Settings attached. Thanks for any guidance!

Thanks, just installed. Will keep an eye on it.

Been getting this a lot lately on 9.7.0. I just installed 9.7.1 beta 6 and it still failed with the same error when attempting to set profiles. Even a reboot wouldn't get it to work, always getting the [HR: 31] error.

I could manually change things like monitor enablement though, so I deleted and re-created both my 2 profiles. They worked reliably.

Then it occurred to me that both my profiles include a Dell monitor connected via USB-C. My laptop has two USB-C ports and I'm not rigorous about always plugging the cable into the same one, so I did an experiment and shifted the monitor back and forth between the USB-C ports.

If I connect the monitor to the same USB-C port as when I saved a given profile, the profile always works. If I connect the monitor to the other USB-C port then the Load Profile fails reliably, though it is of course the same physical monitor.

For now, it's easy for me to just pick a USB-C port and stick with it, but thought you should know.

Circling back. I got the same error using the Beta 6 version. I attempted to open the log to see the details, but got this error:



I don't see a place in the Troubleshooting window to enable logging, though. Where is that option? All the references I found in the forum indicated it should be on that section of the preferences but I don't see it.

I do have a copy of the full System Information if that's helpful.

Here you go. This happened around 7:45pm ET. I have four monitors and two configurations. One config disables the right three and enables the left one. The second configuration reverses that. This only ever happens when moving to the second configuration, and maybe 50% of the time.

Thank you!

Any updates on this, perchance? Hadn't seen this in a little while but just this week it started happening again.

Yes, happened just yesterday. Was working fine for a number of weeks before, though.

Hi there, same issue, sorry to report. Log file is attached, happened at approximately 3:20pm ET.

Not sure what version I was running back in November, sorry to say. I have it set to look for updates automatically so it should have been whatever was current.

It certainly looks like downgrading has solved the issue. Thank you. I guess I'll stick on that version until you tell me it's safe to upgrade?

Copy, thanks.
