When I connect my Toshiba Satellite Pro laptop to my Sony Bravia KDL-55HX853 via VGA cable to play a DVD on the TV, when I play the DVD (or indeed just have the desktop of the laptop on the TV screen) the top quarter of the relayed screen shakes (enough to annoy me when watching). It is not shaking on the laptop so this is something to do with the link. Anyone know how I can fix this? NB the bottom 3/4 of the image doesn't shake!
