Q. See title…. worked fine at first. I had it set to 10 minutes. Now I have to turn my screen on and off manually.

Answer.

For anyone with this problem

After a few days and hours of trying and searching, I found a solution through the Linus tech tips forum.

It seems that its something USB related/connected.

someone on Linus forums said that after unplugging his joystick, the timeout for his screens started working again…

so i unplugged my Xbox controller and within 1min. my screens went off as they should 🙂

so i guess that something is not working as it should in windows, and the reason for only a few having this problem is that they are using some sort of joystick/controller and it keep windows ‘Active’ somehow
