Administrators Hervé Posted November 19, 2020 Administrators Share Posted November 19, 2020 It' been mentioned before: you need to inject the HDMI connector properties to the HDMI output port... https://osxlatitude.com/forums/topic/11410-dell-latitude-7490-with-i7-8650u-intel-uhd-620-and-1920x1080-lcd-mojavecatalina/?do=findComment&comment=94753 Link to comment Share on other sites More sharing options...
Nancy10 Posted November 19, 2020 Author Share Posted November 19, 2020 but that is for UHD 620, mine is HD 620 and i think those properties won't work with my setup. the one i have already are the ones that are supposed to work. am i missing stuff here ?

Administrators Hervé Posted November 19, 2020 Administrators Share Posted November 19, 2020 As I said, the connector properties, not the framebuffer properties. I suggest you read the WEG documentation to familiarise yourself with the matter. https://github.com/acidanthera/WhateverGreen/blob/master/Manual/FAQ.IntelHD.en.md 1 Link to comment Share on other sites More sharing options...
Nancy10 Posted November 19, 2020 Author Share Posted November 19, 2020 Yes, you were right i didn't pay attention to what properties you mentioned. but should i use those exact values ? i did copy those values but it didn't work . i tried using another connector (con2 which is spposed to be te hdmi port) but it still didn't work. i used this as reference to choosing the connector number : Now if we look deeper into your IOReg... FB@0 -> connector-type = 02 00 00 00 and port number = 0x0 (built-in LCD) FB@1 -> connector-type = 00 04 00 00 and port number = 0x5 (no device connected) FB@2 -> connector-type = 00 04 00 00 and port number = 0x6 (external display) Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted November 19, 2020 Moderators Share Posted November 19, 2020 Switch MBP14,3 to MBP14,1 1 Link to comment Share on other sites More sharing options...
Nancy10 Posted November 20, 2020 Author Share Posted November 20, 2020 I tried switching to MBP14,1 but that didn't work. should i delete the framebuffer properties i added earlier and try the MBP14,1 SMBIOS ? Edit : " i deleted the properties but it didn't work either, still no signal on HDMI " 2nd Edit : MBP14,2 worked. Thanks Hervé & JakeLo Link to comment Share on other sites More sharing options...
