Lenovo T580 dual screen not available or even seen by Monterey OS

[alex flora]

Hi All,

 

I have a perfect working Lenovo T580 with only one issue. The laptop doesn't show any external attached monitor, not by using the HDMI port and not by using my USB-C Dock

The laptop is a Kaby Lake Intel core i7 laptop with Intel UHD 620 Graphics

I use OpenCore as bootloader and running Monterey OS Version 12.6

If needed, i uploaded my OC config here: https://anonfiles.com/dbY4weD7yb/OC_zip

Does anyone have a clue where i need to look into or search for ?

 

As model identifier i choose MacBookPro 15,3 but i have no idea if this could be an issue or not
