Never noticed that before! On the right side, near the bottom, totally
flush with the surface.

Holding a finger on the "­" button brings an icon with a progress bar
which gradually turns black all the way from right side to left side.

But, no matter how long you hold the button, the screen itself only dims
by, I'd say, about 30% -- that is, down to maybe 70% of max brightness,
still more than bright enough to use the monitor (or to keep the room
dimly but definitely illuminated at night).

The corresponding screen dimmer F1 key on the keyboard of the MacBook
that's driving the Cinema Display, when held down, dims the MacBook
screen all the way to black.

You may not be able to turn it off manually. Some older models of
Apple's cinema display (perhaps combined with certain versions of Mac OS
X) do not allow you to turn the display off with the physical power
button.

For instance, I'm still using my trusty, old (plastic bezel) 23" cinema
display with Mac OS X 10.5 on my Mac Pro:

On my Mac Pro, with these settings, pressing the power button on the
front of my cinema display does absolutely nothing:

System Preferences > Displays > Options:
[ ] Disable power button
[*] Disable display preferences button

System Preferences > Energy Saver > Options:
[ ] Allow power button to sleep the computer

That said, you can have the display go to sleep automatically (by using
the settings in the Energy Saver control panel).

And you can invoke the screen saver / energy saver display sleep
manually by choosing the Keychain Access menu item > Lock Screen command.

Below the + and - marks should be a power icon. Touch it to switch the
display on/off.

Check the monitor's documentation; it tells you how to configure the
switch;

- Open System Preferences, click Displays, go to the Options tab, and
under Display Power Button select "Turns the display on and off".

The little touch-sensitive dimple on the lower right side of the display
will now control the power of the display only, independently of the
computer.

Lovely! Thank you.

It really ticks me off that this checkbox isn't there in my System
Preferences > Displays > Options panel for my cinema display!

I've become accustomed to just leaving it on and letting Energy Saver do
its thing; and luckily I don't have any USB peripherals that tend to
spontaneously wake the display from sleep. But it sure would be nice to
have a power switch that actually does what power switches are supposed
to do!

Damn you, Apple! >: (

Oh, and I assumed that you were referring to the 20" Cinema Display, and
your 21" was a typo.

If not...
