How to turn off the display on your Mac
You often need to turn off your laptop’s LCD display to save on battery power, but don’t want it to go on sleep. This used to be fairly easy on a Windows PC but I had a hard time figuring out how to do this on a Mac.
Just try this useful but not very commonly known keyboard shortcut:
CTRL + SHIFT + EJECT
I bet you didn’t know this 🙂
