As of Feb 8, 2016, the entire left edge on the display is stained (a dark jagged water mark). Purchased new in June 2009. Hoping others on this support forum with similar problems or those in the know have some insights. This display was used for no more than three years, packaged in its original box and stored for approx. 3 ½ years in an air conditioned storage unit. What is the normal life cycle of any size Apple Cinema Display?
