Hi, i have been on this issue for a little bit now as a new g75 owner. i see the lines and i could see them in that video as well when the camera wasnt shaking. As far as I know its a driver issue. I cant be for sure on this, i really dont know anything too technical about computers. my post has a link to this forum
http://forums.nvidia.com/index.php?showtopic=227767 showing that the problem has existed even with the g74. I have talked to asus and they say to send the computer in, i have talked with best buy and they say any tech will see nothing wrong with it, and i have talked with nvidia and they say the problem has been recognized and is being addressed with asus. I think it has to do with dithering... or that both the video card and the monitor are doing it. Im hoping that the problem will be resolved with driver updates, but i cant get a strait answer out of anyone which makes me worried.
