Hi all, I have a D620 w/ NVIDIA graphics running 10.6.7 and EDP 1.9. I want to connect to an external monitor using VGA, but after connecting the monitor the D620 does not react to it and I cannot find the monitor in Preferences -> Displays. In addition, pressing Fn + F8 to try to toggle view modes always freezes my laptop and I have to force a shutdown. Has anyone else experienced these problems and solved them? I would love to hear your solutions. Thanks in advance
