Randolph Recently I decided to install Windows 7 on my iMac. I have the 27″ Core i5 model, which is a whole lot of screen and power.
Unfortunately, Boot Camp’s drivers for the screen brightness were abysmal, and I ended up getting a severe migraine after playing a game for two hours because it was too bright.
Enter ATI Catalyst Control Center, the alleged savior. Except for some reason, version 11 doesn’t seem to want to install anything that lets me manipulate the brightness.
I eventually found a program (free of charge, no longer supported) called Desktop Lighter 1.4. It is superb. I am now running it at 5% brightness and now it looks like my OS X brightness.
The small matter of the mouse not obeying the brightness rules was remedied by enabling mouse trails, with the short setting, and now I can enjoy the vast expanse of Borderlands on my 27″ screen.
