I think I am being picky that is all because I have looked at the LCD banding pictures and its not like that. I am only seeing it on bf3 and forza. Could even be how the games made because I am not just seeing it in a certain area
Could be an HDMI cable or HDMI input issue. Try switching the cable to another input and if that does nothing try a different cable.
In my case it was the cable. (LG 65LW6500, IPS panel).
The OP's problem sounds very similar to one I had recently, except it was just a couple vertical lines, very visible. They appeared only after playing a solitaire game for a while from my HTPC. Start a new game and bam, there they were. Had to cycle the TV off and on to get rid of them.
