    Projection settings are lost upon reboot

    I have my laptop hooked up to an external display via HDMI. The projection settings made using Winkey + P gets reset to "Duplicate" every time I reboot, and I have to go in and manually change it back to "Second screen only".

    Is there still a way to set this permanently? With Win 7 and 8.x there was a "Multiple displays" option under the Screen Resolution control panel, but this control panel seems to have been completely redesigned in Win 10 and I can't find that option anymore

    Right-click on the desktop and select "Display settings". You can select the internal display and set it to "Disconnect this display".

    However, this may not fix your problem. My computer also resets its display settings on reboot now - it didn't the first several times, but it does now.

    There was another similar post, also a laptop, that wouldn't retain the way it was set on a reboot/shutdown. I don't have that issue on my desktop PC which runs triple monitors. I run dual displays on my laptop but really only ever use Extend. It runs in Extend on boot up if my USB 3 monitor is connected.

    Here is the other thread, External monitor not detected
