network0771 Posted October 31, 2013 Share Posted October 31, 2013 My notebook is Ivy bridge CPU with Intel Graphic HD4000(patched DSDT), and there's a problem that the VGA port doesn't work in mavericks. however, the LDVS and HDMI both work fine! AAPL,ig-platform-id: 01660009 or 01660003 05 03 00 00 02 00 00 00 30 00 00 00 LVDS with QE/CI - Work fine! 02 05 00 00 00 08 00 00 06 00 00 00 HDMI with Audio out - work fine! 06 02 00 00 02 00 00 00 30 02 00 00 VGA - doesn't work i attempt to modify the appleIntelFramebufferCapri, e.g. 06 02 00 00 02 00 00 00 30 02 00 00 06 02 00 00 02 00 00 00 30 00 00 00 06 02 ...... when i click the "Detect Monitor", the notebook will crash. there are methods to enable VGA port on desktop computers, but none of these works on notebooks. And then i saw a post saying that VGA and LVDS can't work together with 1st Generation Intel HD Graphics .so i attempted to disable LVDS,but it came to white screen after reboot (i can hear the sound when i adjust the volume, but the screen is white). Does anybody know how to modify the driver to enable the VGA output. thanks Link to comment Share on other sites More sharing options...
