arcaman6 Posted January 21, 2013 Share Posted January 21, 2013 Hi Guys Just completed installation of 10.7 Lion on D620. Everything sweet except that I am unable to get external monitor working. Have plugged into VGA port but OSX does no recognise that there is a second display - clicking on Detect Displays in System Preferences->Displays has no effect and no secondary displays detected. Clicking Fn-F8 causes OSX to freeze and need to power down to restart. Hardware is working - on booting up with Ubuntu Live CD external monitor works with no problem. Install was done through EDP - only additional work was installation of IO802.11Family.kext and IONetworkingFamily.kext to fix Wifi not working issue. 2GB memory and 2GHz processor - Nvidia graphics card. Can anyone suggest a fix? Many thanks for your help. Link to comment Share on other sites More sharing options...
geo mac Posted January 22, 2013 Share Posted January 22, 2013 I had a similar issue with hooking up a projector , with me it was adjusting the resolution on the display since the output was only 1440x900 and a higher external monitor might not self adjust to display ,but then again that was with 10.6 now with Lion Im not sure but hey still worth a shot., Link to comment Share on other sites More sharing options...
Administrators Hervé Posted January 22, 2013 Administrators Share Posted January 22, 2013 There are limitations with the D620 nVidia... That one or the "gray screen" on display wake. We found no solution to these gremlins to date. Link to comment Share on other sites More sharing options...
arcaman6 Posted January 22, 2013 Author Share Posted January 22, 2013 Thanks for the feedback - very useful. Grey screen on wake up from sleep I can live with - will external monitor work if I install 10.6.3 on same machine? Can you confirm it works with Intel graphics card? Thanks again for the help.

Administrators Hervé Posted January 22, 2013 Administrators Share Posted January 22, 2013 I can't remember if external display can be used under SL, it's too long since I last had SL on the D620 nVidia and even then, I can't remember if I ever tried it... External screen operates on D620 GMA950, but you may experience some corruption at the botton, depending on resolution. All details are here: https://osxlatitude.com/index.php?/topic/1977-external-display-corruption-atabove-1280x1024-edp-v4-r65-and-beyond/page-1 Link to comment Share on other sites More sharing options...
arcaman6 Posted January 22, 2013 Author Share Posted January 22, 2013 Thanks once again. Using external monitor is fairly important to me - can you make a recommendation on a suitable laptop model which will run Lion (or Snow Leopard at a pinch) and properly implements the following:- WiFi, LAN, USB, Speaker, Audio_I/O, QE/CI, VGA, Trackpad, Sleep, Battery.

Administrators Hervé Posted January 22, 2013 Administrators Share Posted January 22, 2013 For VGA, you have 2 modes: mirror or extended. By my own experience, the following models fully support your requirements: - D620 GMA950 - D630 GMA X3100 (VGA in extended mode ok, in mirror mode only with lid closed) - D630 nVidia Lookup the other model sections (Dell and other manufacturers), I've only got experience on the D Series. Also, check the compatibility chart in EDP pages, it lists all supported features, model by model. Link to comment Share on other sites More sharing options...
bobdamnit Posted January 22, 2013 Share Posted January 22, 2013 As of the latest EDP, VGA out now works properly on the D520 as well. Link to comment Share on other sites More sharing options...
arcaman6 Posted January 23, 2013 Author Share Posted January 23, 2013 Thanks for the feedback. Just double checking as compatibility chart lists D620 nVidia as working on VGA and it looks like this is not the case. Link to comment Share on other sites More sharing options...
