Just got a new 27 inch iMac and keep on having to change the brightness level back to the brightness I prefer.


I do not have auto adjust checked, I put the brightness slider up to the level I like and after a while the brightness dims to what seems like the default level as its always down to the same spot on the slider...what gives? i just want it to stay where I want it...



iMac, Mac OS X (10.7)
