My 24" LED ACD's AppleCare will be ending December 15th. I recently purchased this immaculate display from a careful owner who took very good care of the monitor. It is new in every sense of the word. Ideally I would like to use this screen for at least four more years and, afterwards, if all is well, pass it on to a younger sibling. Any tips on how to best care for the ACD through the years? (How often should I wipe it down? / Should I cover the display with some soft cloth in-between usage or during downtime to avoid dust? / This display is currently being used anywhere from 4-6 hours a day - how detrimental would this be to longevity?) etc. Point me towards tips or products - anything that will help. If you haven't noticed, I am incredibly obsessive-compulsive. Please don't tell me not to worry. It is intrinsic in my nature to worry and dote over every facet of my life; and, I like it that way. It works. Much Appreciated.
