I am having a problem with my display. I tried recalibrating the display. I tried using LCD color. I have a negative display with weird colors. It looks like negative photos. If I go online or look at photos it just looks like I am looking at a negative photo. In my Word my normal white page is black and my text is white. Hope I can find help on how to fix this issue. I have a macbook pro bought it in 2011.
