Re: Screen distorted
Try degaussing if that helps. It's in your actual monitor, so just find it in your settings for your monitor. Check the connections for the cable between the video card and the monitor. That's usually the case. Use a different cable and the same monitor. Use a different cable and a different monitor. Single each component out to see what's causing the problem. Post your specs, just in case. And what kind of monitor that you have.
Macbook Pro and Logitech z5500s. All you really need.
