Argh! Mi e' venuta la curiosita' e ho trovato questo! Visto che ne abbiamo scritto tanto, lo riporto qui.
Questo tizio aveva lo stesso problema, ha provato con l'acetone, e poi ha risolto con un prodotto a base di ammoniaca, un "Ceramic stovetop cleaner", il prodotto per pulire le cucine con il ripano in vetroceramica !
Porcaccia !
(Tra l'altro, nella stessa pagina uno dice di non usare l'alcool perche' gli ha rovinato il CRT. mah, mi sa che ogni monitor e' diverso dall'altro...)

4. Monitor Coating Removal atacamaman
Monitor: Samsung SyncMaster 955DF 19"
My monitor had a few scratches on it (thanks Kitty-Kitty) and one day while cleaning the area of my desk with a slightly damp rag sprayed with Simple Green, I wiped across the monitor, as I've done numerous times in previous years since purchasing the monitor. Immediately in the center of the screen were these "spikes" of missing coating. Curses!
Well, this just infuriated me. So to remove the already-damaged screen coating, I proceeded to scrub the rest of the coating off. After all, there was nothing wrong with the monitor.
I tried more Simple Green, amonia, denatured alchohol, and even acetone. This stuff (the coating on the monitor) is pretty tough, and all these chemicals did was remove the top glossy coating. A lot of rubbing later, I only had a small "hole" in the center of the screen which was very annoying while viewing anything. I searched for hours on the internet on how to remove the coating and all I could find was how NOT to remove it and how to clean the monitor properly. I found no articles of other people who attempted to do what I did.
Anyway, after three hours of rubbing and cussing, I had almost the upper half of the screen fully removed. The acetone was not doing as good a job as the simple green - seriously! Amonia is the key here. So I looked under the counter in the kitchen for something else which might contain a mild abrasive and some amonia. BAHM! It hit me! Ceramic stovetop cleaner!
That stuff made the rest of the removal of the coating a bit less difficult. Still, I had to rub and rub and rub. But, it did come off. The abrasive did not damage the glass. And upon completion, I used a few drops of Rainex to polish the surface and restore some of the anti-static properties.
Granted: it's not the perfect screen it used to be, but the viewing is back to normal (no longer have to look thru these flecks of missing coating) and the only spots where there's moire are where I may have rubbed a bit too hard and caused a bit of mild scratching. Overall, it's better until I can go out and spend some money on a new monitor. Which was my other alternative. And I will - when I get the extra money for it.
Meanwhile, I'm able to use this fantastic monitor with a great resolution, wonderful refresh/response times and I can now tell others how to remove the coating if they have this problem.
Remember how they always tell you "never put anything in your ear except your elbow"? Well, never clean your monitor with anything other than soap and water - period! That coating is there for a reason, and it's not easy to remove.
Just a friendly share of thoughts to those who have gone too far in cleaning their monitor.
