I have a HP DV6-6128ca. I just recently discovered an issue I have never noticed before, the two halves of my screen are not in sync. I notice it the most when I am watching a video, and the camera pans or has a lot of movement, straight down the center of my screen (doesn't matter where the video is) you can see the two halves out of sync, it looks like when you're playing games and do not have vertical sync on. I have tried to uninstall Spyder, MacType, and all of my video card drivers, I am just at a loss now. I have the AMD Radeon 6600M and 6700M Series and AMD Radeon HD 6520G drivers installed.
