How to turn down monitor brightness

Hello,

Can you please tell me how to turn down the monitor brightness on my Intel Mac Pro with Leopard? This would be really nice when working at night in a dark room.

The little brightness icon on the keyboard doesn't do anything when pressed. Also, if I go to SYSTEM PREFERENCES, there is no brightness slider under "DISPLAYS" or "Energy Saver".

Thanks,

Kirk

If it is an Apple display, make sure the display's USB cable is connected to the computer. If it isn't an Apple display, the computer cannot control the brightness unless the display came with special software. You will have to use the controls on the display.

You could make a special color profile for the display to reduce its brightness but that would also reduce the number of display levels. For example, if you cut the brightness in half, there would only be 128 levels of brightness, instead of 256.

can be used to reduce brightness via the color profile.
