I have a samsung monitor that i like to use with my macbook pro. When i am finished using the monitor, i turn it off then unplug the DVI cable from the macbook pro. The screen goes blue on my macbook pro but there's nothing on my desktop, it's as if it was left on the monitor screen. So i find that I just shut the lid of the macbook for a few seconds then open and the desktop comes back but is there any way to set it up so that it does this automatically? I also found that if i just unplug the DVI while the monitor is still on, the macbook desktop goes back to normal but i don't like unplugging a cable that is attached to something that is still turned on. thanks for help.
