Is there a possibility in Windows 10 that the screen on the laptop turns on when you flip up the display
I'm not sure about it and maybe I will be wrong, so please wait for others. I think this is an in-build feature that a laptop either has or doesn't have. It may also be possible to set it somewhere in the settings (for example in the energy options).
Open your laptop and click the on / off button.
If you want to connect a second monitor, connect it correctly (HDMI to HDMI, VGA to VGA, …). In the settings you can see the second monitor under the display settings.
