This script did not work on my Dell XPS L702x with 3D Display (it read the product and vendor ID as blank),


But I did it manually and got it working, it is detected as LCD Display but not built-in,


I think I need to get the built-in monitor to get the brightness slider

HI Everyone!


I can't create a topic somehow.

I just replaced my LCD on MBP MID 2012 and the screen only switches on while logging in Macosx Maverick.

Can't rust a diagnose or select different boot drive prior that as screen stays black.


I believe the maC DOESN'T SUPPORT the driver of the screen prior Macosx.


Any ideas suggestions?

Hello and thanks,


Please give some pointers as to what to do?

May I ask your kind assistance?


I did all that was prescribed.


With SwitchResX I get the name I changed to.




In About Mac still says Built-In Display.


I removed all the folders in /System/Library/Displays/Contents/Resources/Overrides


except for the one I created for this display.


what else needs to be configed?


Thanks a million!


Great work
