    Works well with Windows 11 24H2 build 26100.2454! With > doff.exe /l /s Windows gets locked and screensaver is starting. MonitorES didn't work anymore with this feature. 4 stars only for missing a little GUI.

    Dude! You rock!! My power button just went bad on my Dell 24" PC monitor and it's a bummer.... but this makes it all better. Most these utilities just do a full screen BLACK , but this actually puts the monitor in to power save mode... PERFECT. I just wiggle my mouse to bring it back up and Bob's my Uncle. ;-) I love lightweight bat files like this. I made a shortcut on my desktop, I click it and BOOM. Thanks!! DB

    @lestor (see his review below and his request "make it possible not to awaken the screen when moving the mouse"): There is already a free tool (not sure if it's freeware) called "Sordum Monitor Off v1.1" that provides this feature.

    Hello, unfortunately it doesn't work on a tablet. If I turn off the display, background processes will stop working. I assume that it is related to the modern standby mode. It is not possible to wake up the display by touch, it is probably related to the requirements below regarding the mouse. It cannot be parameterized so that it turns off only the display and does not put background processes to sleep, it cannot be woken up by touching the screen
