I have a 9-year old monitor, a Viewsonic VA2226w (22-inch, 1600x1050). It has given me almost trouble free service all these years, but now it has developed an area of white dots on the top right of the screen. It is most discernible when the onscreen image is black, on other colors it gets somewhat hidden. On white you can hardly make it out - but still, it is quite distracting when viewing video or a picture.
It has been there for more than a month, and does not go away, like I have read happens when moisture enters the screen, and goes away after some time on its own.
Can anyone tell me what this is (moisture or something else) why it happened and how I can make it go away? Since this is a very old monitor I would not like to go in for expensive company repairs unless absolutely necessary.
