HaseeMac Posted July 24, 2013 Share Posted July 24, 2013 Hi, all As the topic said, I found only if i connect to the external monitor before starting OSX, and then I can get two display in the system info. Otherwise the external monitor always complains no signal found. I am using 10.8.4 and my graphis card is HD3000 + GT540 (I have disabled the GT540 in DSDT) Any help is highly appreciated.
