pulleyluke Posted September 24 Author Share Posted September 24 @Jake Lo Sorry, here is my EFI, had to strip it down a little due to the upload size limit on this website @WhenMusicAttacks Tried that with no difference sadly. EFI.zip Link to comment Share on other sites More sharing options...
Administrators Hervé Posted September 25 Administrators Share Posted September 25 'tempted to say it's a likely EDID issue but you opted to post screenshots of your IOREg rather the IOReg themselves as asked. Link to comment Share on other sites More sharing options...
pulleyluke Posted September 27 Author Share Posted September 27 Crap sorry @Hervé I was an idiot and didn't know you could export the IOReg Here are the files you wanted (Hopefully done correctly this time) 1440p monitor running at 1080p via dock.zip 1440p monitor via dock.zip 1440p via HDMI.zip Link to comment Share on other sites More sharing options...
Administrators Hervé Posted September 27 Administrators Share Posted September 27 Yes, that's what I was expecting. Your graphics config looks spot on. If you inspect the screen's EDID information, you will notice that the reported data differs between HDMI output and USB-c Dock output: HDMI: <00 ff ff ff ff ff ff 00 05 e3 78 27 d7 00 00 00 09 1b 01 03 80 3c 22 78 2a a5 95 a6 56 50 a0 26 0d 50 54 bf ef 00 d1 c0 b3 00 95 00 81 80 81 40 81 c0 01 01 01 01 56 5e 00 a0 a0 a0 29 50 30 20 35 00 55 50 21 00 00 1e 00 00 00 fd 00 32 4c 1e 63 1e 00 0a 20 20 20 20 20 20 00 00 00 fc 00 32 37 37 38 58 0a 20 20 20 20 20 20 20 00 00 00 ff 00 47 4a 4c 48 33 48 41 30 30 30 32 31 35 01 fc 02 03 1e f1 4b 10 1f 05 14 04 13 03 12 02 11 01 23 09 07 07 83 01 00 00 65 03 0c 00 10 00 02 3a 80 18 71 38 2d 40 58 2c 45 00 55 50 21 00 00 1e 01 1d 00 72 51 d0 1e 20 6e 28 55 00 55 50 21 00 00 1e 8c 0a d0 8a 20 e0 2d 10 10 3e 96 00 55 50 21 00 00 18 8c 0a d0 90 20 40 31 20 0c 40 55 00 55 50 21 00 00 18 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 6d> Dock (both): <00 ff ff ff ff ff ff 00 05 e3 90 27 64 1f 00 00 34 1c 01 04 a5 3c 22 78 3a 48 15 a7 56 52 9c 27 0f 50 54 bf ef 00 d1 c0 b3 00 95 00 81 80 81 40 81 c0 01 01 01 01 56 5e 00 a0 a0 a0 29 50 30 20 35 00 55 50 21 00 00 1e 00 00 00 fd 00 32 4c 1e 63 1e 01 0a 20 20 20 20 20 20 00 00 00 fc 00 51 32 37 39 30 0a 20 20 20 20 20 20 20 00 00 00 ff 00 47 51 4d 4a 43 48 41 30 30 38 30 33 36 01 9a 02 03 1e f1 4b 01 03 05 14 04 13 1f 12 02 11 90 23 09 07 07 83 01 00 00 65 03 0c 00 10 00 02 3a 80 18 71 38 2d 40 58 2c 45 00 55 50 21 00 00 1e 01 1d 00 72 51 d0 1e 20 6e 28 55 00 55 50 21 00 00 1e 8c 0a d0 8a 20 e0 2d 10 10 3e 96 00 55 50 21 00 00 18 8c 0a d0 90 20 40 31 20 0c 40 55 00 55 50 21 00 00 18 f0 3c 00 d0 51 a0 35 50 60 88 3a 00 55 50 21 00 00 1c 00 00 00 00 00 00 00 77> I would suggest you try and inject the HDMI EDID value as additional property in your graphics configuration. Target AAPL02,override-no-connect since this external screen should be 2nd display out of FB@2 and specify the EDID value as DATA type without any space between the bytes. Refer to the Whatevergreen user manual if need be. Can't remember if the AAPL0x unit digit must match the connector's number. You'll be able to check that out in IOReg after reboot (under FB@2->display->AppleDisplay). Can't be AAPL00 for sure as that would be your built-in screen. You may also try to patch connector con2 to HDMI type as per connector con1 though I'm not convinced this will take effect and change anything.

pulleyluke Posted September 29 Author Share Posted September 29 Man I'm really starting to loose hope that I will ever be able to fix this issue Tried injecting the EDID as you suggested with sadly no different result's but you can see that the injection worked correctly as found in the IOReg attached. I will try patching the connector next. Injected EDID monitor connected via dock.zip Link to comment Share on other sites More sharing options...
Administrators Hervé Posted September 30 Administrators Share Posted September 30 Sorry that injecting EDID value did not work. You could also try experimenting with a different KBL frame buffer; like 0x59160000 or 0x591b0000. Link to comment Share on other sites More sharing options...
