Setting to turn OFF Monitor

I have a Samsung Monitor LS27D39xG. In the past it would turn off automatically after a period of inactivity. Now it never turns off automatically. I've haven't timed the interval after which the monitor turns off, but I believe it's between 15 and 30 minutes.
Is there a setting that would control the length of the interval?

Thanks for your help,
PR

    Ivan,

    I'm don't know what I did wrong, but the response I want to your initial question is above "I think Control Panel > Hardware and Sound > Power Options is what I want but it doesn't offer an option to save changes."

    Hi,

    You can go to > Change advanced power settings > Display > Turn Off Display after > and change the settings.

    Or

    Change it to 4 minutes to see if the save option appears; save it, then change it to 5 minutes and save again.

    Thanks.

    Hi,

    You can configure this via Control Panel > Hardware and Sound > Power Options > Choose when to turn off the display.

    Set it up according to your preference.

    Or

    Start menu > settings > system > power > Screen sleep and hibernate timeouts

    You can also configure the monitor itself using the "Off-time Plus" feature described in the manual.
