adams Posted June 26, 2022 Share Posted June 26, 2022 Hi everyone I have macOS Big Sur 11.6.7 installed on Dell Latitude E7270 with OpenCore 0.7.9 by moderator Jake Lo (really thanks for the EFI) but need help with HDMI external display not working properly. I have attached the config.plist that I have used opencore efi and config .zip Link to comment Share on other sites More sharing options...
Administrators Hervé Posted June 26, 2022 Administrators Share Posted June 26, 2022 The only patch you require for HDMI output is the connector type; absolutely no need to patch connector's pipe or flags. You have 2 x very incorrect property injections in your config: framebuffer-con1-enable 1000000 NUMBER framebuffer-patch-enable 1000000 NUMBER Correct statements are: framebuffer-con1-enable 1 NUMBER framebuffer-patch-enable 1 NUMBER or this, if you want to inject the properties in DATA type: framebuffer-con1-enable 01000000 DATA framebuffer-patch-enable 01000000 DATA You've mixed things up. You also confused Opencore EFI folder with module opencore.efi. Former is what one usually posts (in zipped version), latter is of no use at all for debugging.
