mr.kasper Posted November 16, 2022 Author Share Posted November 16, 2022 Thank you! Well, now when connecting/disconnecting the cable, the port display does not freeze the operating system. But there is no image on the additional monitor (the monitor goes to sleep) Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted November 16, 2022 Moderators Share Posted November 16, 2022 Post IOReg file with the monitor connected. Are you connected via DP to DP? DP to HDMI? Link to comment Share on other sites More sharing options...
mr.kasper Posted November 17, 2022 Author Share Posted November 17, 2022 I am connecting a DP to DP cable. The monitor says: the DP cable is connected, and after a while it writes that "there is no signal via DP". The monitor goes to sleep. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted November 17, 2022 Moderators Share Posted November 17, 2022 @mr.kasper You didn't provide the IOReg as requested Connect the monitor. Launch IORegistryExplorer.app and save the file Attach it here Link to comment Share on other sites More sharing options...

Administrators Hervé Posted November 18, 2022 Administrators Share Posted November 18, 2022 If the flags patch still makes no difference, the AGDP patch probably is the last and most likely resort. Details are in my old HD4600 patching guide I linked on p1. Totally linked to device (i.e. Mac model) official capabilities and therefore SMBIOS model selected.

mr.kasper Posted November 21, 2022 Author Share Posted November 21, 2022 Thank you! There is already progress. when I booted from the config1 file (renamed it "without 1"), the laptop booted up with a black screen, an image with artifacts appeared for a second when I inserted / removed the usb flash drive, and connected the display port. When the display port was connected, the image on the additional monitor appeared, but the laptop monitor did not. Link to comment Share on other sites More sharing options...
