Hi there. I am a proud owner of a new 24" iMac and as much I am proud I am disappointed as well. The display is much brighter to the left and dimmer to the right. I took it back to the store and they replaced it with another one, just to have exactly the same problem.
Uneven brightness is not the only problem. The other one is that this thing is damn bright, even at the lowest setting. I use "Shades" and it helps a lot. However, the darker I go, the more obvious the gradient is.
The question is this - is it possible to make a screen overlay with a custom gradient? To illustrate what I'm talking about ... I'd like to have a screen overlay just like the one when you switch on the Dashboard, a transparent black "film" that dims the screen to an acceptable level. What I'd also like is to have it darker on the left and lighter on the right to compensate for the uneven brightness of the screen.
Can this be done?
