I tried setting up your Windows 10 laptop as a second screen for Windows 11, and everything seemed fine until I wanted to turn it off. On the Windows 11 side, I couldn’t find an option to disconnect the displays. The laptop took over its OS and settings, making it hard to access anything. When I powered it back on after restarting, the desktop finally disconnected. It looks like there might be a way to release the connection that I’m missing.
Do you notice a tiny icon showing up on the right side of your Taskbar in your desktop? It resembles a screen with a remote beside it. You should be able to tap it and exit from there. That’s how it functioned when I used my Samsung phone as a secondary display through the hidden menu. Updated November 10, 2023 by DreamCat04 added an important note.
Additionally, pressing and holding Plus (+) while selecting Project will display the menu option.
