Windows 10: turning off monitor at night

how do I make the monitor turn off at night so it doesn't keep the living room lit up?

Night Light Setting and Third Monitor.

Hi Reagan,

We would like to ask you some questions in order assist you properly:

• Did Night light work previously on all three monitors?
• Have you made any recent changes to your PC?
• Are you getting an error message on the third monitor regarding Night light?
• Is the third monitor being detected by your PC?
• What troubleshooting steps have you performed so far?

While waiting for your response, we suggest that you try to connect your third monitor to what you are using on the 2 working monitors to see if it is only a loose connection issue.

Regards.

 

Windows turns monitor on at night.

At night I turn off the monitor but leave the PC running. At around 2-3am, Windows turns the monitor on and it stays on the rest of the night. I have selected "never" on all power schemes. This did not happen with 8.1. Also, during the day when the PC
is idle it randomly switches between lock screen and login screen. While at the login screen the little "busy" circle activates for a few seconds then it goes back to lock screen. Is there a fix for both these occurrences.

I applied all three methods and the monitor did not turn on all night. I appreciate Joy Kemprai providing the solution to this issue. I also appreciate all the other responses.
