I have a standard Macbook. I bought a mini DVI-VGA adapter so I could connect my Sony LCD Multi Function Display and my Macbook together. The connection works fine, but I am having a serious problem with the display. The monitor shows the wallpaper of my macbook but does not show anything I open. So for example, the wall paper is there, but if I open Safari, it doesn't reflect this on the monitor. Only when I try to change the display preferences on my macbook does something show up on the monitor. I tried changing the resolutions to the best of my knowledge, but I'm not overly informed in this matter. Any suggestions?
