Welcome to Discussions

Yes it is Apple / System Preferences / Display / select Display. You can adjust display brightness by sliding blue dot on the Brightness slider bar. Also on the keyboard that came with your iMac and many others you can adjust the display brightness with F14 down and F15 up. The keyborad control is great you don't have to fuss with going into Sys, Pref's. brightness control.

is the brightness control in preferences / displays
on the 24" lcd monitor a brightness or backlight
control? and is the factory default maximum?

This is way late, and you've probably figured it out already. I imagine the questions arises out of you using something like the Spyder 2 Pro to calibrate?

In any event it is a backlight control which is used to change your monitor's brightness.
