I read up on this awhile back, and it is probably bad pixels in the display screen. The display screen is controlled by tiny transistors (tft for thin film transistor). Sometimes they can come from the manufacturer bad, they say, but they can also go bad if you apply too much pressure when cleaning the screen (use the moist screen type cleaners- you can buy them at any computer store- Best Buy, Walmart, etc). If the screen gets bumped too hard, they can be damaged also.
There is nothing you can do in this case to fix it, aside from replacing the whole display. It's conceivable that the driver could have a bad feed to the display screen, and in that case would have to be replaced, but you would probably be better off buying a new computer, in that case. Most likely it's just a bad "spot" on the screen, and although annoying, won't hurt anything if you can live with it. Hope this helps!

How to fix dead pixels


Cheaper to throw away instead of trying to fix, if green is fading the rest will soon follow, I gather it must be near 4 or 5 years old as this seems to be the life span, sorry I have no solution as even dead pixel fixers will not restore lifeless colour, this is usually worn out caps and backlight.

Green dots on screen


Green dots on a LCD screen are burnt out pixels and unfortunately are incurable other than having the TV serviced at a high price. One of the reasons it is a good idea to get a warranty on these types of TVs is primarily due to this very problem....burnt out pixels.
