Dell Lattitude 7480: OpenCore 0.6.1 / Catalina - No 4k resolution


Recommended Posts

Here we are going again :) 

In this topic i wrote what all work, but not. 

HDMI out  is completely not working.

Not detect no one devices (4 TV, and monitor 4k) 

Solved:  wrong model choice in SMBIOS: 14.3 , changing to 14.1 fixed HDMI Out. 

But now i can't get 4k resolution, only 2k.


What i missed in config ? 

May be it is by 1536mb on HD620, not 2048?


Here is config: 7480-no-hdmi_conf.zip
