Just a second opinion... If you're trying to sync up displays in a single
location (ie your office) then this might be worth attempting. But
otherwise, I would say you're probably chasing your tail. In addition to
overall gamma, you will have to contend with monitor-specific
brightness/contrast settings, not to mention the fact that some people don't
even know how to change the number of colors displayed (256 vs 16 or 24 bit)
or even that they *can* change the color depth.
In any event, you can do some hacked display manipulation using a
translucent image object (white, black or grey) and changing its blendLevel.
There are also ink effects that can be employed to achieve other color mix
variations. Off hand I would guess that a brightness slider would display a
translucent white overlay for values from 0 to +100, and black for 0 to
-100. With some experimentation, you might be able to achieve what you need.
