It is an LG monitor and the lines are slight discoleration that start at the bottom and run up the screen in regular intervals. I think it may just need some adjustment on the screen that I can't seem to find.

Are you using a High Def. box

Are you using a High Def. box of any kind? Are the lines greenish and/or reddish in color. Do they move like they're on a conveyor belt, i.e. they're only displayed one at a time, and start on the bottom again once they reach the top of the screen.

If it was the same problem I was having, i would have a reddish line and a greenish line displayed at the same time. It turned out to be the HD cable box. I changed the cables from component to DVI, and the lines went away.
The best way to troubleshoot is to disconnect one component at a time and see when the lines go away. If you have a cable box I would start there. Cable TV is still a breeding ground for interference and line noise, despite it being digital, thus high technology devices tend to suffer and pick that garbage up a little more than the good ol' tube TVs.
