Here is a video: http://www.youtube.com/watch?v=WJeBx1cB5m4
Sometimes, when my monitor wakes from a sleep, half of the screen will be distorted. I noticed, when I made this video, that if I open the Internet browser, the screen will be fine but only the parts of the screen exposing the desktop will be distorted (top most and bottom most of the browser window). But then, if I watch a video in full screen in the browser, half of the screen will be distorted again. If I turn off the monitor and then turn it back on, the distortion will be gone. Does this sound like a monitor issue, a graphics card issue, or something else?
