vanquybn Posted January 6, 2016 Author Share Posted January 6, 2016 Other than not being reported as "built-in LCD Display", are there any other problems? The LCD is clearly detected as Apple Display under display0 of the 1st nVidia framebuffer, so that's Ok. Are you getting your resolution Ok? Are you getting full graphics acceleration at all? Can you post a screenshot of the AppleDisplay IOReg content under NVDA,Display-A@0->display0 ? I would expect this to show the detected EDID. Try the attached SMBIOS, but no guarantee it'll work... smbios.plist.zip Thank you for reply: Are you getting your resolution Ok? => Yes, I get full resolution on both internal LCD and external display via HDMI Are you getting full graphics acceleration at all? => Yes, I get full graphics acceleration on both internal LCD and external display via HDMI Can you post a screenshot of the AppleDisplay IOReg content under NVDA,Display-A@0->display0 ? I would expect this to show the detected EDID. => Yes, EDID is detected properly: I have tried your SMBIOS configuration, but there is no different.

vanquybn Posted January 7, 2016 Author Share Posted January 7, 2016 Attached file is my IOREg and DSDT. It is already patched Device PNLF Please be noted that your NVD graphic cards is real "built in", it's built in your main board. My NVD graphic cards is not built-int, it is "plug and play" with bus "MXM 3.1 Type A". So i think this is cause of problem. Archive.zip Link to comment Share on other sites More sharing options...
vanquybn Posted January 8, 2016 Author Share Posted January 8, 2016 I have tried the DSDTs, but it still the same: DSDT1: DSDT2: Link to comment Share on other sites More sharing options...
vanquybn Posted January 8, 2016 Author Share Posted January 8, 2016 Well, I admit defeat then. You could always try to remove the Device (PNLF) totally from Device (GFX0) to see it makes any difference... Yes, I also tried it and got the same result. I think my LCD port or NVD quadro port is cause of problem. Link to comment Share on other sites More sharing options...

2bad0 Posted January 20, 2016 Share Posted January 20, 2016 To get it to display as built in you might need to inject built in flag and also make sure that your smbios is that of a mac with built in brightness and nvidia gpu like imac or macbook try this if you use clover 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 Using clover configurator,paste this in Devices/properties windows and check inject. Make a back up copy of config if it somehow mess up your output. Link to comment Share on other sites More sharing options...
2bad0 Posted January 20, 2016 Share Posted January 20, 2016 Yes "built-in" is the only needed flag ,This string was not meant as a permanent fix,I prefer to test with strings because it's much faster(for me),then when i get a working combo,work it into dsdt. As far as osx is concerned it detects the lcd on a display port rather then edp/lvds hence considers it external monitor. There is also AAPL,HasPanel AAPL,backlight-control which may or may not be needed if the above fails. Link to comment Share on other sites More sharing options...
