    Apple 21" Cinema Display connected to MacBook 10.4.11 in mirror mode:
    how to turn the Cinema Display off, or turn its brightness down to zero,
    without disconnecting (or unpowering) it?

    [There's a brightness slider in the Cinema prefs panel, but it only dims
    the Cinema Display a bit, far from fully off.]

  2. Don't know about that model, but mine has a proximity switch on the
    side. The Displays:Options Preferences panel selects what that switch

    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.
