I've been using DisplayFusion for about two years for a 3 monitor setup, and have a few profiles saved that I've been using to toggle different layouts.

Some of the Profiles are set to disable certain monitors. However, DisplayFusion no longer seems able to successfully disable monitors. It won't work from the menu popup in the Taskbar to select a different profile, nor will it work if I try to disable it manually in the Profile editor of DisplayFusion.

This has been a problem across at least the latest 2 versions of DisplayFusion, so I'm not sure where to look otherwise. Could it be an issue caused by my video card drivers?

System Specs
DisplayFusion Pro 11.0.4
Windows 10
NVIDIA GeForce 2080ti w/ latest drivers
2x LG Monitors connected via DPI; TCL TV connected via HDMI

Hmm, I have tried this, and settings still don't seem to take after I try to apply. I can't disable any of my monitors -- it prompts me with the "Keep these changes?" dialog, as if a change has been made, but my monitor arrangements stay the same.

I also can't seem to change and save the cloning settings either.

Yeah more than happy to help!

At 2:06 PM EST I attempted the following:
- Disable Monitor 2 entirely
- Set Monitor 2 to be a clone of Monitors 1 and 3

Both attempts failed.

Debug log is attached!

Just wanted to comment that I had this same monitor issue when I upgraded to v11, rolled back to 10.x and have been golden since. But it's definitely a thing, I think my main monitor, when I loaded up the profile for all monitors on, got "disabled" somehow and it seemed like I couldn't get it to even come back on, be it through DF or Windows display settings. Uninstalled and reinstalled a 10.x version with the same settings in place and have had 0 issues since.

I also suddenly have this same issue since today. I switch a lot between various Monitor / TV set-ups but DisplayFusion seems unable to Disable or Enable screens via profiles now. Disabling also can't be done via "Monitor Configiration" but Enabeling does still work "manually" there. Let me know if I can help by also sending info.
(DisplayFusion Pro on Steam 11.0.4)

Just to give a bit more information.

For me it seems like it is not as "easy" as just being unable to enable monitors. Sometimes is enables some but not all monitors (which ones varies) and fails to apply other settings like duplicate monitors, main monitor, orientation ect.. And disableing doesn't work at all I think.

Right on! Enjoy the holiday, and thanks for looking into this!

Any other information I can provide to diagnose feel free to ask.

I think it prolly has a lot to do with the TV being involved in the equation, as my setup is similar and I use my TV as a display pretty often. Either that or something about it being HDMI when my two actual monitors are DP.

I did notice a new version dropped! However I'm still seeing the same issue. Debug output is attached.

I attempted at around 11:30 AM EST. I did two tasks, one I knew would be succesful, in case that helps to provide any more debug data to suss out.

- Tried to disable monitor 2 (failed, same as before)
- Switched Monitor 2 from Portrait (flipped) to Landscape (it worked), and then I chose to not keep settings, and it reverted fine

Hope I did it right, did not see an "Aplly" after selecting "L1: Log Minimal", so asume it does that automaticly. I do have a pretty weird set-up with 3 Computer screens, 2 TV's and a beamer hooked up with various splitters and duplicators. But it worked fine before.

Local time (CET (UTC+1)):
~18:50: tried going from profile "TV/Boven/Beamer" (Monitor 2 + 4 Duplicated) to profile "TV Only" (Monitor 4 only). Recieved "Keep changes" box but Monitor 2 + 4 where still Duplicated.

~18:51: tried to go from "TV/Boven/Beamer" (Monitor 2 + 4 Duplicated) to profile "Bureau" (Monitor 2 + 4 Duplicated / Monitor 1 Enabled / Monitor 3 vertical Enabled).
Recieved "Keep changes" box but still only Monitor 2 + 4 where Duplicated while others where disabled.

~18:52: Tried again, same result.

~18:55: (First "manually" enabled Monitor 1 & 3, this worked) Tried to disable Monitor 1 "manually". Recieved "Keep changes" box but monitor was still enabled.

~18:56: Tried to disable Monitor 3 "manually". Recieved "Keep changes" box but monitor was still enabled.

Hope this helps, if more is needed let me know. Hope you guys can fix it soon as I make all these switches multiple times a day, but first have a good new years / holidays.

Yeah, as I said I have a pretty unconventional set-up that took some workarounds to get functional, that is also why I am so happy for a program like DisplayFusion to help me with this.

"Monitor 1" is a MSI Optix MPG341CQR 34" 1440P 21:9 Ultra Wide Monitor.

"Monitor 2" is actually a 3 way splitter that goes to a 1080P 27" IIYAMA monitor and a 1080P Epson Beamer (no fixed screen size). These might be on or off independently from each other. To get around Windows annoying hotswap / monitor on/off detection it also has a "HDMI Dummy Plug Headless Ghost 4K Display Emulator" plugged in the splitter.

"Monitor 3" is a 1080P 21" Dell standing vertically.

"Monitor 4" is actually a splitter that then goes to 2 different models of 55" Samsung 4K TV's. For this one to get around Windows hotswap detection it is connected to the computer via a "hacked" Female to Male HDMI Adapter that blocks the hotswap signal.

If I remember correctly my Receiver is outside of this loop and only recieves the audio from the computer via a optical toslink connection.

I did make a couple of changes to my set-up somewhat recently, but it still worked for a while after and the set-up before that was pretty compairable and worked fine for a long time.

Please let me know if I can help with any more information.

(Please excuse any spelling issues, Dyslectic and English is not my first language + no spell checker here)

I have mine via steam and it is also updated via steam, can I still do this?

Sadly it is not fixed for me using 11.0.6 (Beta 2).

Between 22:30 and 22:35 (CET) I tried going from "Bureau" to "TV/Boven/Beamer" and it only changed the "Main monitor" from "Display 1" to "Display 2+4" but did not disable "Display 1" and "Display 3". I switched back to "Bureau" profile and then tried to disable "Display 3" manually, this also failed.

I did some further testing and it seems like the main problem comes from something to do with duplicated displays.
I was able to correctly enable or disable separate screens as long as no screen was duplicated. But as soon as I had either "Display 2 + 4", "Display 2 + 3" or "Display 4 + 3" as duplicated it started to fail being able to disable other displays or unduplicate them etc.

Please let me know if I can be of any more assistance, but I will probably not be able to reply untill next year.

Thank you for the quick updates, sadly it still does not work correctly. The behaviour has changed though, it now clones screens instead of disabling them.

For the log file:
Between about 13:57 and 14:16 local. (-> = changed into / hope this formating is clear for you?)
1. Started at neutral all monitors on state (2 / 1 / 3 / 4) -> 2+4 / 1 / 3 -> tried to disable 3 = 2+4 / 1+3

2. (for this one I starting to doubt if I missed the "Keep changes" button) Used normal windows settings to go back to neutral -> "profile: Bureau" -> profile: TV/Boven/Beamer = No changes in end result still "profile: Bureau" layout.

3. Tried again to go from: "profile: Bureau" -> profile: TV/Boven/Beamer = 1+2+3+4 (all screens duplicated, in windows setings shown as 1+2 as I think it duplicated 1+3 and then duplicated this with 2+4 into 1+2+3+4?)

4. Used Windows settings to go back to 2+4 / 1 / 3 and tried to unduplicate 2+4 = Long wait where it tried (screen 4 flikkered on and off multiple times) but eventually failed and stayed in 2+4 / 1 / 3.

Hope this helps, if you need any further clarifications and / or info let me know.

Pretty similar situation to other folks. I have 3 monitors I use and then a fourth I sometimes use which is just a TV connected via HDMI. It clones my left most monitor when active and then I disable it when not in use. It no longer lets me disable the TV (monitor 4) whether via loading a profile that doesnt include it or by trying to in the display fusion profile management menu.

On first testing this version works for me. I will let you know if I run in any issues with further testing / use.

Helpful for me to test with this version as well? This fix attempts to address this issue as a whole, or just the issue BTA was having?

Happy to try one of the BETAs if more testing would help out.

Ah! Yes, it's working again for me. I can disable succesfully, and then re-enable succesfully as well.

Same for me, my profiles for monitors all work again. Thanks!

Hello
I had the same probleme (2 monitors + 1 TV) and my presets doesn't worked anymore since version 11 (can't disable the TV, inverts left and right screens, etc...)
The last Beta found in this topic fixed the problems, thanks

Thank you! Appreciate you all getting this problem fixed!

I came upon this thread because I was having a similiar issue relating to a cloned monitor, and the beta version 11.0.6 beta 5 had fixed it!

Thank you!
