[pawan2joy]

Here is the revised config and IOreg file.. No change

i have attached the HDMI output working EFI for your reference, see if we can incorporate the changes in our EFI to make it work (file was big so provided link here)

Please help

Release V1 · khoi-ttc/ThinkPad-X390-Opencore-EFI-Sequoia

It would be good to check if the Laptop BIOS has any settings for DVMT.
