Resolved Screen will not rotate after Windows 10 install

I have a Dell Inspiron 11 3000 Series, which functions as a laptop and tablet. Since I upgraded to Windows 10, the screen will not rotate. I have checked the settings, but have not found anything that will resolve the issue. Has anyone else experienced this with Windows 10? If so, what is the resolution?

 

I received mine about a week ago. It came with Windows 10 already on it. Last night I was experimenting with some keyboard key combinations for another reason and had the screen suddenly rotate 90º. I didn't know exactly what I'd done to cause that, but some more fiddling got it back to the way I wanted it. I think the keys were the Home and End keys along with the Ctrl and Fn and Alt keys, some combination of them. Sorry I can't provide the exact fix for you, but I did have the same thing happen on a similar machine and I somehow got the mistake sorted out. When you get yours fixed, let us know which combination was the winner.

 

Try ctl+alt+arrow.

 

Thanks. I will try your recommendation the next time the screen locks up.
