Windows 10 Screen Automatically Extends

I have had no issues with Windows 10 except for an annoying second monitor issue. About one in three times that I open my laptop and power on my second screen, it will extend the desktop, which is what I want. The other two times, however, both the laptop screen will turn on and the monitor screen, but the desktop screen will turn off and it will be set to second screen only. It's a little nit-picky, I know, but it's frustrating that it changes settings like that. Is there a way to set it to always set to extend automatically, not second screen only? The strange part is that it seems to switch on its own. I'm using a Dell Inspiron 13 connected via HDMI.
Hi Djosh,

Thank you for posting your query in Microsoft Community.

To extend the displays on Windows 10 , I suggest you to follow below steps and check if it resolves the issue.
1. Right click on Start > Control Panel.
2. Change the view by option on the top right to Large icons.
3. Select Display > Change Display settings on left panel.
4. Select Extend these displays from the drop down menu of Multiple displays.

5. Click on Apply and then OK.

Hope this helps. If the issue remains unresolved, please get back to us and we would be happy to help.

I think I could have been more clear.

My setup is a laptop, which I treat more like a desktop as it usually stays on my desk, and a second monitor off to the left connected via HDMI. I usually turn my computer off at night, but during the day I just shut the screen. 

The problem is that sometimes, when I reopen my screen, it will automatically extend, which is what I want. But most of the time it will go to second screen only, which is what I don't want, meaning that the second monitor is on, but not my laptop screen. I know how to quickly change the settings back to extend using the keyboard, so this problem is really more of a minor annoyance than anything, but it's getting on my nerves after a couple of months. 

So in short, my computer seems to choose between display settings when I open it up with no rhyme or reason as to if it chooses 'extend' or 'second screen only'. Is there a way to make it stay at 'extend' setting indefinitely?

Hello DJoshquay,

Did you find a solution for your problem?

Thanks in advance
