Thanks!  your config did it:   Working  HDMI! 

Look at this! :     from the left to the right:  

Dell Latitude 3400     -        USB-C to HDMI convertor  (ali-express 5 € )    -     build in HDMI out

A  very useable system:  above all expectations!

Working: 

everything, except the Trackpad (and VGA-out,  but I guess, that is impossible)

You have to use the Opencore bootloader, not Clover.  You can use this EFI.

Halo Jake,

 

thanks for still helping me out! 

 

added the aml files to ACPI to my bootUSBstick and use added config.plist:

Track-pad still not working.. :-(

 

Still booting from USB stick,  the Dell Lat. 3400 can boot both Windows10  and big Sur. 

 

posting my new IOreg file.

 

extra question:  is there any change that imessage & facetime going to work?   (not yet tried...)
