My desktop picture imprinted on my screen
For the last year, I've had the same desktop picture on my iMac screen (picture of a cruise ship). I've never noticed this problem until today: the lines and contour of the cruise ship are imprinted on my screen. When I change my desktop picture to a solid color, I still see the lines and contour of the cruise ship! Is there a way to fix this or is my monitor pretty much garbage. As a graphic designer, these lines are very distracting and I can't work like that...
Thank you for your help.
