I bought a 24 inch LED ACD a few weeks ago and ordered an iKlear cleaning set in addition. After some weeks I had to use it for the first time: I used the cleaning fluid and the clothes from the set in the way described on the box. Now the glossy screen (that I like !) is not only a little bit dull but pattern-like structures are visible at the surface, especially when viewed from the side. Very annoying effect. It can't be wiped off with a dry cloth and looks like there was some kind of default screen coating (maybe applied unevenly) that became visible by the cleaning procedure. iKlear is the cleaning agent recommended by Apple Tech Support and I ordered it from Apple Online store as I did the display. Any known issues or similar problems with the LED ACD so far ?
