i have hunted but i cannot seem to find the answer to this specific question: i understand monitor mirroring, monitor spanning, etc. i also understand that you can use the MBP in "clamshell mode" so that the video card is only driving the external monitor by plugging in the external monitor, closing the MBP and putting it to sleep, then waking it with an external keyboard/mouse. my question is, i would prefer to run in clamshell mode with the MBP partially open - just an inch or so to allow the LCD not to be directly on top of all the heat when gaming. is it possible to do this with the MBP LCD completely OFF thereby still giving the external monitor all of the GPU RAM? i thought that if you went to clamshell mode and then popped open the MBP a little it would automatically refresh and mirror/span to the MBP LCD? note that i would be doing this in Windows XP home under bootcamp for games. thanks in advance!
