Sony, and my Macbook

[MacLax22]

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?

In System Preferences-->Displays you could either select display syncing/mirroring (=> content of both displays is the same) or drag the manu-bar to the attached display to make it your primary display.
