Hello I do not know how to search for this topic on google I got a fairly new macbook 13, the last model before the firewire. I notice something very weird. The screen brightness changes. At first I thought I am imagining or maybe its like LCD's where color and brightness changes from one angle to the other but that is not the case... If i come closer to the screen it takes a bit then it lowers the brightness, if I go further it does the opposite. If I adjust the screen it happens too, and I notice it happens a lot more if I am sitting in a darker room that a bright room. I can almost swear the isight it doing some adjusting by its own calculating my distance from the screen. These are LEDs I believe. Any one heard of such a thing? What is this? Sometimes to happens while I am reading an article without moving.
