I have a 14'' iBook and recently bought an LG 19'' Widescreen monitor. I am testing a Dell 17'' on it right now before I open the LG one, but my problem is that the same screen shows on my ibook and the external. This isnt what I want. I have read you are supposed to be able to close the laptop and then it shifts to the external display but this is not working for me. this is my goal: use my bluetooth keyboard full time have my ibook closed at all times have my external as my main display how do I make this work?
