I'd like to know what's in these fancy cleaners. I bet it's all just marketing and you can make them with common household cleaners for ~$5.
i'm not sure....EVERYWHERE i hear people say that ordinary glass cleaner has some chemicals in it that can damage the LCD's screen ( by deteriorating the screen ). And that you should use LCD screen cleaner.
though, i'v never looked much into it, to see if that's true or not. either way, i still bought LCD cleaner simply because i don't want to take chances on my HD LCD tv. cost me too much money to have something as simple as glass cleaner to damage it.
just did some quick looking....someone said that ethyl alcohol and ammonia-based cleaners can yellow your flat-screen or laptop monitor over time. So you should use chemicals that don't have those in it. they said Eye glass cleaner works well
and Viewsonic's website says..
"If still not clean, apply a small amount of non-ammonia, non-alcohol based
glass cleaner onto a clean, soft, lint-free cloth, and wipe the screen with only a
slight pressure. Too much pressure may damage the screen."
so basically, don't use Windex, or anything else with ammonia or alcohol to clean your screen, and you should be safe.
