I am in desperate need of help before I start tearing my hair out. I have a Macbook OS X 10.6.8. For several months I have had connected a Samsung SyncMaster P2370 monitor attached via VGA-mini DisplayPort. I've never had any problems whatsoever until today. I pressed Shift-Command-Eject (I meant to press Option-Command-Eject) and it started playing up.
First the external monitor went to sleep. My macbook still worked as usual but when I moved the mouse over to the extended desktop on the external monitor it remained black (though itunes, which was open on the external monitor, continued to play). During my attempts to revive video on the monitor, which included putting the whole laptop to sleep and then waking it up again, restarting the computer, unplugging the monitor and replugging it, the display would randomly wake up, work fine for anywhere from 10 seconds to 3 minutes before going back to sleep.
Then however, after one episode of restarting the computer, the external monitor no longer registered at all as being connected. Now I can't even get my macbook to recognise that there is a monitor attached at all. I've been trawling through the forums and using google to try to find an answer. The closest I came is someone who mentioned that control-shift-eject may turn off video output. Nothing about shift-command-eject. And even if this is what has happened, I can't work out how to turn it on again. The fact that it started exactly when I pushed these keys makes it seem likely that it is not a monitor or connection problem, but I'm still stumped.
Help!!
