Hi, I have an Envy All-in-one 34" desktop.
For some reason, regardless of how I set the "Power & Sleep" settings, the monitor does not shut off when I expect it to. Also it never goes into sleep mode.
This all used to work. Nothing that I know of has changed.
Suggestions?
Thanks in advance.

These kinds of issues are nearly always caused by vide drivers -- and even though you have not updated those drivers yourself, MS Windows Update will do that on its own -- without your permission and without telling you.
So, to check for such updates, open Settings --> Update & Security --> Windows Update --> View update history
If you see a recent video driver update, then try to uninstall that update. If that works, then follow the instructions in this thread to disable driver updates: http://www.tenforums.com/tutorials/48277-driver-updates-windows-update-enable-disable-windows-10-a.h...
