Quickly and Easily Put Your Mac’s Monitor to Sleep

I have a Mac in my bedroom, and sometimes I use it right before I go to sleep. When I lay down, I usually don’t fall asleep until the monitor goes to sleep, stopping my screen saver from flashing. Is there a quick way to put my Apple monitor to sleep right away, without shutting off the computer?

It doesn’t sound like there is much worse than laying in bed while your screen saver illuminates the walls and ceiling with all sorts of colors. You could pull the covers over your head… or you could use Exposé hot corners to put your monitor to sleep!

Exposé is a feature of Mac OS X that allows you to control your desktop with ease. Exposé has all sorts of neat tricks built in, like auto-arranging open windows and clearing everything away to show the desktop. The Exposé feature you are going to use in order to quickly put your display to sleep is Active Screen Corners.

Active Screen Corners allow you to assign a different action to each corner of your display. For instance, you can tell Exposé to start your screen saver when you touch the top right corner with the mouse, or show all windows when you touch the bottom left corner. One of the actions you can assign to a screen corner happens to be Sleep Display.

Step 1: Go to System Preferences

Go to your System Preferences by clicking its dock icon, or clicking the Apple symbol (top left corner), then System Preferences. When the System Preferences window appears, click on “Exposé” (”Exposé & Spaces” for Leopard users).

Step 2: Configure Active Screen Corners

Under Active Screen Corners, you will see a drop-down menu next to each corner of your desktop. Decide which corner you would like to touch with the mouse in order to put your display to sleep, then select “Sleep Display” from that drop-down menu. Here is a screen shot:

Once you have made this selection, everything is set. You can close the System Preferences window, and touch the corner of your screen to which you assigned “Sleep Display” in order to turn off your monitor. Sleep well!
