This is an unfortunate side effect of DisplayPort monitors disconnecting themselves from the computer when entering sleep mode. Windows detects the monitor disconnect/reconnect, and it does a full monitor detection, causing the windows to shuffle around. We have a Scripted Function that may help with this. Here's how to set it up:

• On the DisplayFusion Settings > Functions tab, click the "Download Scripted" button
• Double-click the script named "Save/Restore Window Positions on Sleep/Resume"
• Give it a key combination and click OK
• Click Apply and press the hotkey to start the script

You'll have to run it manually the first time. If it seems to work for you, let me know, and I'll tell you how to make that script startup automatically with Windows.

Thanks!

That scripted function isn't really necessary any more in the latest beta versions. Here's an updated guide: https://www.displayfusion.com/Discussions/View/automatically-save-and-restore-window-positions-on-sleepresume/?ID=fa98975e-e4ed-45de-afe0-fafad56c7a83

Hope that helps!
