I got a macbook pro about a week after the late 2011 refresh. Ive noticed when I'm viewing websites that have a black background that there's a slightly noticeable black streak up the center of the screen. It doesn't go straight up though it kind of goes up at an angle. Also the part of the screen that has the dark streak feels hotter to the touch than any other part of the screen. I tried to take a picture of it but it doesn't really show. What could this be? And what will apple do if I make a genius bar appointment? Will they replace it, or have to send it in for service? I bought it about 2 1/2 weeks ago.
