You can also get this solution in lens or spectacle shop.
what to say there?
Cover it when not in use,
avoid keeping the monitor near windows
clean with lcd cleaning cloth and solution to eliminate spots.
I remember earlier we used to get some covers for the CRT Monitor, Cabinet, Keyboard, printer etc which were made of a material which was like thin cloth. Not sure which material it was. My cousin told me that material will absorb less dust it seems. Can we use these covers to cover the LCD Monitor?
