    I don't have an exact answer for you, but short of unplugging it, I don't think you can power it off. I use a number of external HD's connected to the LG's USB-C connections. IF my laptop is disconnected or turned off, my externals are still spinning. I'd rather not have them running needlessly without my connected laptop, so I've got into the habit of disconnecting the HD's also. You'd think they had a power switch on the monitor! A workaround might be connecting the monitor to a power strip, and just powering off the strip, but I don't know if that would have any long-term issues for the monitor.

  • The best method that I have for turning OFF this LG display, and the Apple Thunderbolt/Apple Cinema Displays, is by setting up a "Hot Corner" where you move the mouse into an assigned corner of the monitor to initiate putting the display to sleep.


    Go to:

    ~System Preferences
    ~Mission Control
    ~Hot Corners... (Bottom left of Mission Control menu)

    ...then select the corner that you would like to have as the assigned Hot Corner, open the Drop Down Menu, and select "Put Display to Sleep" and the display will go into Sleep/Standby while still supplying power to your MacBook Pro.
