Is this hurting the computer/graphics card? Everyday I plug my external monitor into DVI port on my MBP. At first, I would do this while the computer was off. Now, I'll just plug it in while the computer is on. And I almost never screw in the screws. I unplug the same way. Part of me feels like I am playing with fire every time I do this. The other part of me feels like this magical machine can do anything and this is what it is made to do. Most of the time I find that the computer will usually detect the external right away with the quick blue screen flash and then boom, 2 monitors. I say usually because I sometimes have to go and detect the displays in system pref's manually. Another glitch is sometimes after plugging in, the menu bar at the top of the external only goes 3/4 way across the top of the screen (when this happens, it seems to go away by itself after a bit). And every once and while, my dock disappears from both monitors completely. Every thing else is fine, just no dock. Then I have to go and play with the arrangement in the display settings until I can get it pop up again. I found I was having even more problems (or more frequent of the above) when I would unplug/plug in while the computer was asleep so I switched to doing it while it was on. Am I crazy for doing this with a brand new MBP? Should this only be done while the computer is off? Any feedback is appreciated.
