I attached my file of IORegistryExplorer, but it not docked to PR03X. Is it enough? At the beginning when I saved it to a file, I found it around 43MB, I thought I made something wrong., that is why I did not upload it. I can see FB#1 has been changed from port 5 to port 7. In this situation, if I dock my laptop to PR03X or undock it, no information changed on port 7, only changed something on FB#2 port 6, when I plug monitor to dock, I noticed the system log has some information, it says "DisplayPipe Capabilities Extended are not supported on offline Fbs", whether it is because the HDMI port on laptop was disabled when it docked to PR03X and DP, DVI and VGA port on PR03X is shared with this HDMI port? By the way, I applied the patch to config.plist, did not make any changes to the kext file. But it seems work. E5250_patched_port5_to_port7.zip

Today, I connect to PR03X and connect only one Viewsonic monitor to it. I tried to patch FB@1 as you metioned above, no display. Patch layout 0x16160002, FB@2, port 6, change connect type to 0008, 0004, 0002, still no display. Whatever which monitor I connect to my laptop or PR03X, DVI, DP, VGA, HDMI, I can only see information changes on FB@2 from IORegistryExplorer. FB@1 had never changed. If I run FBPatcher, I can see only one monitor appears on Connector tab, I can see the model of my monitor connected to DP, If I disconnect it, I will see the monitor information of the monitor connected to DVI port. But still no display on each monitors connected to PR03X. And, how I can collect information from IORegistryExplorer and upload it to this thread? Thank you.

I am new to this IORestryExplorer, I'll try it. I learned something from https://osxlatitude.com/forums/topic/10305-e5470docking-stationport-replicator-pr03x/?tab=comments#comment-76468 I found @1 port 5 is 08 HDMI, @2 port 6 is 04, DP port, when I connect each monitor individually, some information change on @2 port 6, no changes on @1 port 5. Also, I checked AppleIntelBDWFrameBuffer file via vi in hex mode for layout 0x16260006, I found port 5 and 6 are both 04, means it's DP port. 16260006 is for HD 6000? But mine is HD5500, whether I need to change my ig-platform to 0x16160002 (HD5500, 1.5G VRAM) and patch layout 16160002? Also, I found someone says I need to patch it through Whateverygreen? I am confused, keep trying. Than you for your tips. Still working on it.

I docked my laptop to PR03X: 1. Connect to DP (with DVI convertor) to ViewSonic. 2. Connect to DVI to Dell Monitor. Got the same result as both monitors connected, system can not boot. 3. Without both monitor, system boot up. Then I run IORegisterExplorer and take three screenshots 1. No monitor connected. 2. Connect to DP. 3. Connect to DP and DVI. Please help me to check it. Thank you.

Thank you, I will try it when I am at home.

My CPU is 5200U. ViewSonic connect to DP port and Dell Monitor connect to DVI port of PR03X. I just tested with two monitor connected, lid was closed, when I tried to boot, I got the that screen information, in this situation, if I press some keys on keyboard, I can hear some keypress sound from speaker, after I open lid, system completely stopped, no display on both monitors and laptop display. If I open the lid and turn on the computer, no display on both monitors connected to PR03X.

My E5250 works fine with Mojave, sound, touchpad etc. But if I plug it to PR03X with two monitors connected, I can not boot up my Mojave, my CLOVER and error screen attached. Thanks.e E5250.zip
