    Is this possible? I've been testing with my energy preferences to put display to sleep after 1 minute, but my external Asus monitor never goes in to sleep mode.

    How can I set this up to that it happens automatically after a period of inactivity? I can't use any keyboard commands or hot corners (this is for my parents). The display simply need sot go to sleep after a set period of inactivity.

    How to do this?
