I'm going to have another go at reproducing the issue here and we'll go from there.

Thanks! ]]> RE: Monitor profile change via command line sometimes fails, if PC is locked https://www.displayfusion.com/Discussions/View/monitor-profile-change-via-command-line-sometimes-fails-if-pc-is-locked/?ID=3ea04a4b-7a6b-4906-b863-9bf22e118191#28 Wed, 08 Apr 2020 22:21:30 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/monitor-profile-change-via-command-line-sometimes-fails-if-pc-is-locked/?ID=3ea04a4b-7a6b-4906-b863-9bf22e118191#28 DisplayFusion the photos screensaver is a built-in one, but I also tested it with the "Mystified" screensaver, which is another microsoft screensaver, and got the same results. Would you like me to enable logging, and give you the logs? ]]> RE: Monitor profile change via command line sometimes fails, if PC is locked https://www.displayfusion.com/Discussions/View/monitor-profile-change-via-command-line-sometimes-fails-if-pc-is-locked/?ID=3ea04a4b-7a6b-4906-b863-9bf22e118191#27 Wed, 08 Apr 2020 19:24:12 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/monitor-profile-change-via-command-line-sometimes-fails-if-pc-is-locked/?ID=3ea04a4b-7a6b-4906-b863-9bf22e118191#27 DisplayFusion If you choose a different screen saver (one of the built-in Windows ones maybe?) does that make any difference? ]]> RE: Monitor profile change via command line sometimes fails, if PC is locked https://www.displayfusion.com/Discussions/View/monitor-profile-change-via-command-line-sometimes-fails-if-pc-is-locked/?ID=3ea04a4b-7a6b-4906-b863-9bf22e118191#26 Wed, 08 Apr 2020 14:35:32 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/monitor-profile-change-via-command-line-sometimes-fails-if-pc-is-locked/?ID=3ea04a4b-7a6b-4906-b863-9bf22e118191#26 DisplayFusion Yes the issue still ocurrs, even if it's not set to lock the desktop. ]]> RE: Monitor profile change via command line sometimes fails, if PC is locked https://www.displayfusion.com/Discussions/View/monitor-profile-change-via-command-line-sometimes-fails-if-pc-is-locked/?ID=3ea04a4b-7a6b-4906-b863-9bf22e118191#25 Tue, 07 Apr 2020 20:44:34 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/monitor-profile-change-via-command-line-sometimes-fails-if-pc-is-locked/?ID=3ea04a4b-7a6b-4906-b863-9bf22e118191#25 DisplayFusion Ok, thanks! As a test, if you disable the option to lock the desktop when the screen saver runs, does this issue still occur? I'm wondering if it's the screen saver that's breaking it, or the fact that it's locking the desktop when the screen saver runs. ]]> RE: Monitor profile change via command line sometimes fails, if PC is locked https://www.displayfusion.com/Discussions/View/monitor-profile-change-via-command-line-sometimes-fails-if-pc-is-locked/?ID=3ea04a4b-7a6b-4906-b863-9bf22e118191#24 Mon, 06 Apr 2020 20:40:33 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/monitor-profile-change-via-command-line-sometimes-fails-if-pc-is-locked/?ID=3ea04a4b-7a6b-4906-b863-9bf22e118191#24 DisplayFusion No. It was in screensaver mode, using the photos screensaver. if I switch modes, while displays are in sleep mode, it works as intended. It also works fine if I move the mouse to stop the screensaver first.

The error message I can just disable again. It's the failure to switch that got me. ]]> RE: Monitor profile change via command line sometimes fails, if PC is locked https://www.displayfusion.com/Discussions/View/monitor-profile-change-via-command-line-sometimes-fails-if-pc-is-locked/?ID=3ea04a4b-7a6b-4906-b863-9bf22e118191#23 Mon, 06 Apr 2020 19:15:44 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/monitor-profile-change-via-command-line-sometimes-fails-if-pc-is-locked/?ID=3ea04a4b-7a6b-4906-b863-9bf22e118191#23 DisplayFusion Thanks for the update! Were the monitors asleep when you tried to change the profile from the mobile app? ]]> RE: Monitor profile change via command line sometimes fails, if PC is locked https://www.displayfusion.com/Discussions/View/monitor-profile-change-via-command-line-sometimes-fails-if-pc-is-locked/?ID=3ea04a4b-7a6b-4906-b863-9bf22e118191#22 Mon, 06 Apr 2020 03:28:43 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/monitor-profile-change-via-command-line-sometimes-fails-if-pc-is-locked/?ID=3ea04a4b-7a6b-4906-b863-9bf22e118191#22 DisplayFusion This problem reared it's head again, but this time, using my phone to change displays.

I'm currently using beta 9.6.2, and this time I tried to trigger the change, while the Microsoft Photos screensaver was active (which also locks the desktop), and Windows is up to date.

this is a new install of windows, since the last time I posted, and had no real issues after the last post until today.

Here's what happened...

Screensaver was on for about 5-ish mins
used phone to trigger display change, got nothing.
went to other display, unlocked PC, and manualy changed displays.
saw the error in the uploaded screenshot.
Clicked OK, and watched it revert.

Note that i no longer do this with voice commands. I use the PC, or the phone app only now. ]]> RE: Monitor profile change via command line sometimes fails, if PC is locked https://www.displayfusion.com/Discussions/View/monitor-profile-change-via-command-line-sometimes-fails-if-pc-is-locked/?ID=3ea04a4b-7a6b-4906-b863-9bf22e118191#21 Fri, 26 Jul 2019 19:42:55 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/monitor-profile-change-via-command-line-sometimes-fails-if-pc-is-locked/?ID=3ea04a4b-7a6b-4906-b863-9bf22e118191#21 DisplayFusion Logging set to 1.

We could figure out it's the voice software or DisplayFusion that's not working while the screens are idle, like this:

On the DisplayFusion Settings > Troubleshooting tab, change the Logging drop-down to "L1: Log Minimal" and click Apply
Let the computer idle for long enough to cause the issue
Say the voice command and note the exact time you issued it
Wait 1-2 minutes, then move the mouse and unlock the computer, check that the command completes, then note the exact time again
Click the "Export Info to File" button on the Settings > Troubleshooting tab
Reply with the file attached
Disable debug logging after sending the log

That way we can compare what time you issued the command with what time DisplayFusion received the command

I can tell you that if I lock the PC, and wait for the displays to turn off, then issue the command moments later, it will work just fine. This failure came after the PC was idle for several hours. ]]> RE: Monitor profile change via command line sometimes fails, if PC is locked https://www.displayfusion.com/Discussions/View/monitor-profile-change-via-command-line-sometimes-fails-if-pc-is-locked/?ID=3ea04a4b-7a6b-4906-b863-9bf22e118191#16 Thu, 25 Jul 2019 01:47:11 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/monitor-profile-change-via-command-line-sometimes-fails-if-pc-is-locked/?ID=3ea04a4b-7a6b-4906-b863-9bf22e118191#16 DisplayFusion Yeah, I wonder if it's Push2Run that's not working when the displays are asleep, or if maybe DisplayFusion can't use the Windows monitor configuration API while they're asleep. If you just wake the displays and say the voice command, everything works, right? ]]> RE: Monitor profile change via command line sometimes fails, if PC is locked https://www.displayfusion.com/Discussions/View/monitor-profile-change-via-command-line-sometimes-fails-if-pc-is-locked/?ID=3ea04a4b-7a6b-4906-b863-9bf22e118191#15 Wed, 24 Jul 2019 23:08:39 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/monitor-profile-change-via-command-line-sometimes-fails-if-pc-is-locked/?ID=3ea04a4b-7a6b-4906-b863-9bf22e118191#15 DisplayFusion Push2Run https://www.push2run.com/

I know it works when the desktop is locked, as i've used it that way before, but may not work, when displays are in power saving mode (eg when they are off) ]]> RE: Monitor profile change via command line sometimes fails, if PC is locked https://www.displayfusion.com/Discussions/View/monitor-profile-change-via-command-line-sometimes-fails-if-pc-is-locked/?ID=3ea04a4b-7a6b-4906-b863-9bf22e118191#14 Wed, 24 Jul 2019 13:24:50 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/monitor-profile-change-via-command-line-sometimes-fails-if-pc-is-locked/?ID=3ea04a4b-7a6b-4906-b863-9bf22e118191#14 DisplayFusion What app do you use for the voice commands?

Desktop is locked
Voice command is issued, nothing happens
Desktop is unlocked, command executes immediately (without re-issuing the voice command)

I saw the command prompt for it open as soon as I unlocked the PC, but that was 30+ seconds after issuing the command, so I'm going to have to guess that it didn't even try. ]]> RE: Monitor profile change via command line sometimes fails, if PC is locked https://www.displayfusion.com/Discussions/View/monitor-profile-change-via-command-line-sometimes-fails-if-pc-is-locked/?ID=3ea04a4b-7a6b-4906-b863-9bf22e118191#10 Tue, 23 Jul 2019 14:54:44 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/monitor-profile-change-via-command-line-sometimes-fails-if-pc-is-locked/?ID=3ea04a4b-7a6b-4906-b863-9bf22e118191#10 DisplayFusion Do you know if the DF command tried to run at all while the PC was locked? ]]> RE: Monitor profile change via command line sometimes fails, if PC is locked https://www.displayfusion.com/Discussions/View/monitor-profile-change-via-command-line-sometimes-fails-if-pc-is-locked/?ID=3ea04a4b-7a6b-4906-b863-9bf22e118191#9 Tue, 23 Jul 2019 04:33:36 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/monitor-profile-change-via-command-line-sometimes-fails-if-pc-is-locked/?ID=3ea04a4b-7a6b-4906-b863-9bf22e118191#9 DisplayFusion Today was the first big test. Was away from the PC all day, then came back and issued a voice command to cxhnge displays before even touching the mouse. It executed the command to change displays, but only after I unlocked the PC this time. ]]> RE: Monitor profile change via command line sometimes fails, if PC is locked https://www.displayfusion.com/Discussions/View/monitor-profile-change-via-command-line-sometimes-fails-if-pc-is-locked/?ID=3ea04a4b-7a6b-4906-b863-9bf22e118191#8 Mon, 22 Jul 2019 16:16:16 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/monitor-profile-change-via-command-line-sometimes-fails-if-pc-is-locked/?ID=3ea04a4b-7a6b-4906-b863-9bf22e118191#8 DisplayFusion Sounds good, thanks! ]]> RE: Monitor profile change via command line sometimes fails, if PC is locked https://www.displayfusion.com/Discussions/View/monitor-profile-change-via-command-line-sometimes-fails-if-pc-is-locked/?ID=3ea04a4b-7a6b-4906-b863-9bf22e118191#7 Fri, 19 Jul 2019 22:58:28 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/monitor-profile-change-via-command-line-sometimes-fails-if-pc-is-locked/?ID=3ea04a4b-7a6b-4906-b863-9bf22e118191#7 DisplayFusion So far, but this was from my phone as opposed to the voice command method. The voice command method told my computer to run the DF command line to change monitor profiles, while the PC was locked.

In place Edit: I setup a workaround for the app I use to trigger the command line with a voice command, then used commands to change between 4-5 different configurations. No errors, and no failures, except for misunderstood commands, which was on Google, or me. If it happens again, I'll post again here.

Thanks!
