Running DF Pro 9.9 on Windows 10. 2 Nvidia Quadro cards - P620 and P400, 6 monitors.
When I change monitor profile using a hotkey, occasionally Windows will lock up, requiring me to do a hard reset (pressing physical reset button on PC). The lock up happens immediately after pressing hotkey to change monitor profile. This has happened twice in the last 2 days.

Wondering if you guys have seen this before and if you have any ideas on troubleshooting.

Screenshots from Windows Reliability Monitor:

Can you update to our latest beta and let me know if the issue persists? We've re-worked our monitor configuration code, so you'll need to delete and recreate any monitor profiles after updating. Here's the link to download the beta: https://www.displayfusion.com/Download/Beta/

For more details on the changes to the monitor configuration code, please see this post: https://www.displayfusion.com/Discussions/View/monitor-configuration-backend-completely-revamped-in-displayfusion-100-b18/?ID=b17dacd1-0611-48c1-a29c-3a3e5046812a

I updated to the beta, and it's been working great. No freezes when changing monitor profile since updating to the beta.

I was on v10 beta for ~6 weeks and didn't have this issue once. I updated to v10 this past Sunday and this morning, after waking the PC, I pressed the hotkey to change monitor profile and PC instantly locked up - same issue that started this thread.
Please can you provide a link so I can go back to v10 beta?

Thanks for link. I'll post back if the beta is running without issue. And if you see any possible culprits in the troubleshooting file, please let me know, thanks.

If I install the beta over the existing v10 installation, will my monitor profiles be preserved?

Everything looks good there. If you install the beta directly overtop of your current install, it will maintain your settings, yep!

Beta 27 was a disaster for me. Installed it Sunday (yesterday), restarted PC, put PC to sleep. Woke PC Monday (this morning), hit shortcut key to switch monitor profile and PC locked up. This evening, after switching from 6-monitor profiles to my 2-monitor profile, I tried hotkey switch to my 6-monitor profile and another lockup.

These lockups both with v10 and with v9 occur (sometimes) when I switch to a more numerous monitor profile, which for me is typically switching from 2-monitor profile to 6-monitor profile.
I just installed the earlier beta that ran for ~6 weeks without a lockup, v10.0 Beta 21

Was beta 21 the last beta you tested before upgrading to v10.0?

Yes.
So it seems something between beta 21 and beta 27 changed that is affecting my setup. I have 4 x QHD monitors and 2 x 4k monitors, and several monitor profiles, though I most often switch between a 2-monitor profile and 6-monitor profile.

Sure. I'll install Beta 23 this weekend and let you know how it goes, thanks.

I installed v10 Beta 23 on 4/30 Sunday. So far so good, though I notice beta 23 takes longer than beta 21 to switch from my 2-monitor profile to my 6-monitor profile, and while switching, some windows get moved to the monitors that are coming online before reverting back to their original location. But no lockup yet, so that's good.

This morning 5/4 Thursday, v10 Beta 23 locked up the PC when I tried to switch from my 2-monitor profile to my 6-monitor profile. So I moved back down to Beta 21.
If you have a Beta 22, I can try that to maybe help narrow down where things changed, causing this instability.

Installed beta 22 on May 7, and it's been working great so far.

So maybe a change between betas 22 and 23 as it relates to monitor profiles or profile switching?

Thanks for confirming, we'll take a look into it and see if we can find anything.

Edit: We've also changed the way DisplayFusion handles loading profiles via hotkey in our latest beta. Could you try it out and let me know if the issue persists?

I've been on Beta 22 for 2 weeks now, and it's been great - not even one lockup when switching profiles. Clearly something changed between betas 22 and 23.

Are you referring to v10.1, Beta 3?

Could you update to Beta 23, and send over a dump of the DisplayFusion process when it's hung? You can grab the dump via Task Manager > Processes > Right click DisplayFusion > Create Dump File.

Yep that's correct, 10.0 Beta 3.

Thanks!

Installed v10 Beta 23 yesterday and had a hang today (clearly a big difference from Beta 22). After restarting PC, I see 4 DF processes, and I captured dump files for all. The DF process and DF Service process both have dump files larger than 50MB, which is the max file size I can upload via this forum. Suggestions on how to proceed?

Conditions to create a hang; I think these are necessary, but not sufficient, meaning these conditions don't guarantee a hang, but make it much more likely:

1. As noted earlier, hangs usually seem to happen when switching from 2-mon to 6-mon profile. Don't think it's ever happened in reverse. It may be possible to induce hang going from 1-mon or 4-mon profile to 6-mon, but I rarely do that, as 2 and 6 mon profiles are by far the ones I use and switch between the most.

2. Hang usually seems to happen under the following sequence: put PC to sleep while in 2-mon profile, wake PC up, then switch to 6-mon profile. If it doesn't hang at this point, then I can switch back to 2-mon, then back to 6-mon and it does not hang.

I will now install v10.1, Beta 3.

If you have something like WeTransfer or Google Drive that should work. We should only need the process from the main DisplayFusion.exe as well.

Thanks!

Thanks for sending that over, it doesn't look like there's anything too interesting there. Could you update to our latest beta (10.0 beta 4) and send over 2 dumps, about 10 seconds apart?

I've been on 10.1 Beta 3 since 5/28 and no issues so far. Would dumps from Beta 3 be useful? If not, I will update to Beta 4 this weekend.

And you want the dumps only if there is a crash or even without a crash?
Jun 5, 2023  • #25
Owen Muhlethaler (BFS)'s profile on WallpaperFusion.com
Interesting, we only need the dump when there's a crash. If beta 3 checks out for you, can you try beta 4 and see if it crashes?

Let me get a few more days on Beta 3 to be somewhat confident it doesn't have the hang issue. I'll update to beta 4 over the weekend.

PC locked up on 10.1 Beta 3. It was the typical pattern - had PC on 2-monitor profile, put PC to sleep last night. Wake PC up this morning, and a couple of hours later, engaged hotkey for 6-monitor profile, and PC locks up.

After the lockup on v10.1 Beta 3 on 6/9/2023, I went back to v10 Beta 22 on 6/11/2023. Unfortunately Beta 22, which had been solid up to this point, locked up this morning. Same pattern as usual - PC on 2-monitor profile, put PC to sleep last night; wake PC up this morning, and a couple of hours later, engaged hotkey for 6-monitor profile, and PC locks up.

It doesn't look like anything is showing there either, that's really strange beta 22 is acting up now as well. Can you try the following:
  • Open the Windows Task Manager
  • On the Details tab, right-click the column header and choose "Select columns"
  • Enable these columns: Handles, Threads, User Objects, GDI Objects
  • The next time this happens, send me a screenshot of those stats, along with the CPU and memory usage stats for DisplayFusion.exe and also for explorer.exe

So you want a screenshot of those stats *after* rebooting following a crash?

Are you able to grab it before you hard reset the computer?

No. When I say that sometimes changing monitor profiles 'locks up the PC', I mean it locks it up. Keyboard and mouse are unresponsive.

Are you able to note down the numbers DisplayFusion is using for each column before you reset it? Even a general ballpark should be enough to let us know if it's abnormally high

I recently had v10 Beta 21, which had been very solid up to this point, lock up the PC. This was the straw that broke this camel's back. I switched to a competing product. So if no one else is having this problem, I guess you can disregard this issue.
