In the Monitors cdev, there's a checkbox titled 'Use Special Gamma'.
(To find it, hold down the option key and ckick the 'Options...' button.)
It installs some kind of gamma correction, but what does that mean?
How does it effect my system?  I assume that it has something to do
with the color tables.

When using the IIci's onboard video and Apple's protrait monitor, it 
lists 2 possible selections when checked: Mac Portrait Std Gamma and
Uncorrected Gamma. I leave mine set to Mac Portrait Std Gamma of course,
but I've not noticed any difference with the other two settings.

Let me summarize this note in one sentence: What is all this Gamma
correction stuff anyways?
