Hi,
after getting a new monitor for my setup, display fusion is having trouble applying a saved profile:
Profile 1 has a secondary 1900x1200 and the primary 4k display (this one is new and used the be 1440p)
Profile 2 is a 4k TV.

When swapping from profile 1 to 2, everything is ok. But the swap from profile 2 to 1 breaks something: both displays of profile 1 become mirrored(they are suposed to be seperate) and are set to the 1900x1200 resolution, it also seems like it is cycling through several resolutions for the 4k display. In the display fusion monitor setup window I can't change the resolution or disable the mirroring after this happens, I have to use the built in windows display settings.

I used the same setup without any problems for years, just with a differnt primary display for profile 1. Already tried to reset all settings and deleted/recreated both profiles.

Also checked out the L1 debug log, which I attached

In the Nvidia Control Panel > Manage 3D Settings, do you have "Image Scaling" turned on?

Its deactivated in the global setting and was activated for a single 3d application. I just deactivated it completly, no change in the behavior.
I also just tried a reinstall of all nvidia drivers/software, which didn't change anything as far as I can tell.

Did you recreate the monitor profiles after reinstalling the Nvidia software?

Okay interesting, we had another customer experience the same thing and it was one of those Nvidia settings that was causing it.

Could you send me a copy of your troubleshooting info? Here are the steps:

  • Open the Settings > Troubleshooting tab
  • Click the "Export Info to File" button
  • Reply with the file attached

In general I don't use any Nvidia settings, the only exception beeing image scaling for a single app and - until I got my new monitor - custom color settings for my old main monitor. I set them back to the default values before I was even aware of this problem though.

Just a heads up that we're working on some changes for the next beta that should hopefully help out here. We'll follow-up as soon as it's available to try out.

Thanks!

We've got a test build of DisplayFusion 11 Beta 1 that we're not quite ready to release to everyone through the auto-updater, but thought you might like to try out as it may resolve the issue you reported. This beta has some very big behind the scenes changes that will improve performance, speed up startup times, re-organizes the main settings window, and adds real time settings changes. We've done a lot of internal testing, but be prepared for a few bugs. We'll collect feedback over the holidays and review it all in January.

Please take a backup of your settings (Settings > Options > Export) before updating and store them outside of the default folder. If you need to roll back to 10.1.2, you can download it at https://www.displayfusion.com/Download/ and install it over top of the beta.

If you'd like to give it a try, you can download it here: https://www.binaryfortress.com/Data/Download/?Package=displayfusion&v11-test=1

Hello, and thanks for the reply. Sadly it doesn't change the behavior, although I still am not sure if its caused by something on my system(drivers, something monitor/dpi scaling related) or displayfusion. It still seems to hang(DF window not responding) for a bit after swapping profiles while failing to extend the display to both monitors - and instead mirroring it.

Could you try re-saving the profiles and let me know if that makes any difference?

Thanks!

I recreated the problematic profile a few times after installing the beta. The changing seems to work just fine if the target profile has just one monitor (4k TV or my main monitor, both dpi scaling), but as soon as I use my two main monitors in a single profile it always clones the picture.

Ok, thanks for trying it out! We'll keep working on this issue for the next beta.
