Strange Graphic Problem May be an Artifact

When I play a game in 1080p I get these weird horizontal lines when i look up and down mostly on terrain and foliage but its not picked up on video or photos Also if I play in anything below such as my native resolution 1336x768 its not there. Its as if there is a net or something just behind the photo its hard to explain.
I play on a 32" tv not a monitor and my GPU temperatures never go past 50 so its not a temperature problem also its doesn't happen in every it happens in a lot of them though. Any game with a cell shading to it like orcs must die borderlands. Also Batman Arkham city is not affect but games like Skyrim, Mass Effect Call of Duty and Crysis are badly affected. I will Photoshop some images to show you what its like.
