One key thing I probably should have mentioned is that I'm using a lenovo docking station.
Regardless, I tried the settings that are suggested in the link but my windows still switched screen and stayed there.

So I concluded that the windows must somehow switch screen after or right after I lock.
I therefore changed the setting to save window positions when I lock.
This workaround works, thanks! ]]> https://www.displayfusion.com/Discussions/View/windows-automatically-switch-screen/?ID=e02c19e9-8d2f-46c3-93e4-4c902acf5905#2 Fri, 09 Sep 2016 18:52:46 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/windows-automatically-switch-screen/?ID=e02c19e9-8d2f-46c3-93e4-4c902acf5905#2 DisplayFusion Is one of your monitors a DisplayPort monitor? When they go into sleep mode, they get treated as disconnected by Windows. When this happens, the displays get re-detected and DF has to reload the taskbar. I think the combination of the taskbar reload (which causes the work area to change), and the display re-detection is what causes the windows to get shuffled around. You can automate the saving/restoring of the window positions with DF though. Please see this guide for details: https://www.displayfusion.com/Discussions/View/automatically-save-and-restore-window-positions-on-sleepresume/?ID=fa98975e-e4ed-45de-afe0-fafad56c7a83

Hope that helps! ]]> https://www.displayfusion.com/Discussions/View/windows-automatically-switch-screen/?ID=e02c19e9-8d2f-46c3-93e4-4c902acf5905 Thu, 08 Sep 2016 12:15:06 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/windows-automatically-switch-screen/?ID=e02c19e9-8d2f-46c3-93e4-4c902acf5905 DisplayFusion Before using DF I had an issue in windows10 where I would unlock my running laptop and all windows from the second monitor would go to my laptop - very very annoying.
This did not happen all the time but once or twice a day.
Thought that I would use DF again so I fetched the upgrade to 8 and I run it portable (laptop from work - can't install anything).
Now however, it happens nearly everytime I unlock the laptop again, all screens switched from the secondary monitor to my laptop.

I googled the issue before and it might have something to do with windows changing resolution after unlocking.

Does DF change the resolution as well when unlocking? There is a clear difference in using the standard functionality in win10 and DF.

It feels like my secondary display is plugged out each time, but I checked the cables numerous times.

Any ideas? ]]>
