Moderators Jake Lo Posted February 19, 2018 Moderators Share Posted February 19, 2018 Answer in RED Doesn't work: Sleep Works but I get a destroyed Screen after waking up. Custom EDID already in Config, just need to enable Inject EDID If Monitor goes out it stays black even after patching edid (tried different options air 16:9 / MBP 16:10 - here I couldn't even get to login) Same as above. Do you have different resolution than 1366x768? which guide did you follow? Sound doesn't work. It can't find any Input or output device Attachment re-upped in post#8. Just need to replace the DSDT.aml Brightness doesn't work - even after Karabiner Copy the SSDT-PNLF.aml to /E/C/ACPI/Patched Card Reader not found Not supported yet.

burzlbaum Posted February 19, 2018 Author Share Posted February 19, 2018 Thanks for the fast reply! How do you know all this stuff... The missing Card Reader is sad but doesn't hurt. Maybe its working in the future. Sound works now! But with the EDID Code activated I get another black screen instead of login. I followed that guide and have a 12,5" Full HD 1920x1080 Display and I tried different EDID Codes. The only one that didn't left me with a black screen instead of login screen was this: 00FFFFFFFFFFFF000610F29C000000001A150104951A0E7802EF059757549227225054000000010101010101010101010101010101012E3680A070381F4030203500149C1000001A5C2B80A070381F4030203500149C1000001A000000FC00436F6C6F72204C43440A2020200000000000004121A4010000000A010A20200087 On the picture you can see my Settings that lead me to that Code. I also attached my generated edid and DisplayProductID in the Zip. If I try to Pick MacbookPro or Override Display with AppleBacklightDisplay it leads to a Black login Screen. The Brightness still won't work I really appreciate all your help! /edit Brigthness Keys are working but it doesn't matter what I do its at max or dark.

Moderators Jake Lo Posted February 19, 2018 Moderators Share Posted February 19, 2018 do you have AppleBacklightInjector.kext in /L/E? I don't need the EDID injector for my E7470 with 1920x1080 display but need it for E7270 with 1366x768 Try getting the backlight control working and see if maybe you don't need the EDID either...hopefully Link to comment Share on other sites More sharing options...
burzlbaum Posted February 19, 2018 Author Share Posted February 19, 2018 i have the kext in S/L/E if I deactivate EDID I still have the problem my Display stays black after monitor went in power-saving. If I send the Notebook in Sleep and wake it up I get this Screen Error. My Brightness still won't work. After Start its in a normal Brightness but if I higher it - its at max and I can't lower it until its almost black. Link to comment Share on other sites More sharing options...

burzlbaum Posted February 20, 2018 Author Share Posted February 20, 2018 Thanks for your reply! If I deactivate EDID I get black screens now at start instead of login so I put my "working" edid in again. Don't know what I did exactly with that script but I attached the out coming debug zip with the command u recommended. Thanks for all your support. debug_16887.zip Link to comment Share on other sites More sharing options...
burzlbaum Posted February 24, 2018 Author Share Posted February 24, 2018 Little Update. I tried a lot of things. Most of the time to fix the Brightness Problem. I realized that my blackscreen after Monitor Standby doesn't have to stay black. If I press the F12 Key to higher Brightness the Monitor comes back. But with the same Graphic Error like waking up from sleep. Seems macOS doesn't load my display prober after sleep / standby. I hope I don't tell you stuff you already noticed... Well even me knows what might cause the problem - but I have no clue how to solve it. Btw. i don't use the EDID right now since nothing seems to help.

Display class and Override Display Class both should be AppleBacklightDisplay Link to comment Share on other sites More sharing options...
burzlbaum Posted February 24, 2018 Author Share Posted February 24, 2018 Hey Jake Lo I did not but I did a huge progress! I remembered, that I got a black screen instead of login with your and my created edids. So I tried again to create one with MacBook Pro 16:10 and both apple backlight. I used a different guide this time where only the 20byte and checksum was edited. But what should I say... it kinda worked. I got again the black screen instead of login tried to put brightness to max (F2) and I got a shiny login screen. After login I tested brightness with F11 / F12 because now my Karabiner started. Well no Brightness changing only max or black. Then I tried sleep and after waking up I had NO Graphic Bugs! And suddenly my brightness on F11 / F12 and in System-Display works aswell. So most Hacks have a problem with their Brightness after waking up from sleep and I have a problem before waking up from sleep xD I am very happy right now but how do I fix the rest? Other edid testing? Or is there another solution? /edit tried iMac and MacBook Pro with FIXEdid. worked exactly like my own one. Black at Login. Everything working after waking up from sleep. - strange Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted February 24, 2018 Moderators Share Posted February 24, 2018 try deleting Nvram.plist in /EFI. Reboot and let it create a new one. You could also try booting with -f arg Link to comment Share on other sites More sharing options...
