chriz74 Posted March 5, 2015 Share Posted March 5, 2015 The only problem is that I don't get extended display if I boot with the external hdmi display plugged, the internal one lights up but no picture is displayed. Any clue?If I hotplug the hdmi display when already booted I got extended correctly, also if I close the lid the external becomes primary and if I reopen the internal turns on again correctly.So how comes this doesn't work if booting with the hdmi display already plugged in? My system specs suggest hd4000 id 1660009 so I put that in the dsdt instead of 1660003 Then applied these patches:for lvds internal video to workAppleIntelFramebufferCapri 010000000200000030000000 to 050300000200000030000000for hdmi and dviDVI (probably not needed as I only have an hdmi port)AppleIntelFramebufferCapri 020500000004000007010000 to 020500000008000006000000HDMI (audio works)AppleIntelFramebufferCapri 030400000004000007010000 to 030400000008000006000000 Link to comment Share on other sites More sharing options...
WaldMeister Posted April 5, 2015 Share Posted April 5, 2015 Hi, On my HD4000 i applied this one on 01660004. For the external devices the DVI and HDMI from 01660003 have been used.
