Green Dots on scren

[Nazarii]

I have green dots on my Asus K56 C screen. They disappear if I move lid in special position. I think this is screen problem. Could this be a driver problem?

If it changes based on the lid position, I'll estimate 98% chance that it's hardware. The best possible cause would be a slightly loose cable, but I don't recommend poking around inside a notebook that you need unless you have previous experience.

Stuck pixels perhaps? You could try something like JScreenFix and see if that helps.
