Why is my 17

Q: I have noticed horizontal lines from an inch to the whole screen thick when im in the login screen to my PC and it also does it on my background. kinda like.. if I have two windows up, the window that is active wont flash, but everything in the background will. It is only two years old and it's off Warranty. anybody know why it might be doing this?

A: It could be graphic card related have you tried the montior on another computer? Do you have a surge protector on your equipment. Check your display setting if they are correct for your monitor size.
