Probook 6570b with Mojave - External screen not working

Hello together, I am messing around to get an external screen working on the Probook 6570b with a fresh install Mojave. I've done everything like Chris explained in the tutorial but can't get it to work. Somebody has got a solution or tips for that?
It is the Probook with the High resolution screen.
As soon as I plug in the DisplayPort cable, the Mac wouldn't boot anymore. If I plug it in while it is running, no picture on the external screen is shown.

Would be great to find a solution for that!

Thanks

Did you try VGA Port ?
You can try with RDM.app on your Applications

Yes, on the VGA Port is no signal, as well.
The RDM App doesn't recognise the external screen, as well.
Any other suggestions? I really need the external Port for an external screen.

This is an issue with  a High Screen 6570B because mine works  with a low screen
Try to setup Dual link in config.plist and reboot

Code:


<key>DualLink</key>
<integer>1</integer>


Hi, thank you for the suggestion. Sadly that did not solve my problem.
To be sure I've tested the DisplayPort Port and the VGA Port with a Windows system - they are working properly.

Do you have any other suggestions or shall I post my config.plist or other? Please let me know! Would be awesome to fix this problem, then it would be a perfect Hackintosh.

Best regards,
Skylinar

What is the SMBIOS you have? maybe trying a different smbios?

Confirming here that's not working on the Probook 6570b High Screen
