Looking for some setup assistance. I have a MacBook and an external monitor. The monitor is widescreen, with a 1440x900 resolution. I've successfully hooked up the DVI connectors and the monitor is working. I have mirror mode running, so the monitor and laptop display the same thing. I want to do this: 1. Get the monitor to use 1440x900 resolution. Mirror mode has the monitor displaying at 1280x800 (the macbook display). 2. Close the macbook so that it still runs, but the screen is off. 3. When I want to use the macbook on its own, be able to pull out the DVI cable, and have the macbook resolution return to 1280x800. Essentially, I want to only use the widescreen monitor while I'm at my desk, and then I want to be able to pick up the laptop, sit in the living room, and use it normally. How do I do this? Thank you!
