So I recently purchased a refurbished white Macbook. The display is model 00009C5F (without the lines) but I've found the colors to be way off. See if you can tell the difference between my external monitor and the macbook. External Monitor White Macbook Anyway, is this a defect or just fault of bad calibration? It's really off sometimes - I enjoy the color contrast on my external monitor much more than the Macbook. Any help is appreciated.
