  • macbook pro 15-inch, Early 2011
  • external samsung monitor, attached using HDMI to Thunderbolth adaptor


Previous Situation


With Snow Leopard I was able to keep the macbook screen open but turned off and use only the external monitor. This way I was able to use the front camera to make conference having everything only in the external monitor.


Current Situation


With Lion as soon as I open the macbook monitor the image splits between the two monitors and I'm not able to set the extenal one as only one.

MacBook Pro, Mac OS X (10.7)
