[HELP] Laptop Thinkpad T540p can not get 32bit color depth (ig-platform-id 0x0d220003)

[lighting2]

My laptop model is thinkpad t540p
CPU- i5-4300M, Intel HD 4600
RAM 12 GB


I followed this tutorial
https://www.tonymacx86.com/threads/guide-booting-the-os-x-installer-on-laptops-with-clover.148093/

I create usb installer and install to HDD successful with invalid ig-platform-id ( to passthrough installation step)

I have to change to 0x0d220003 to get Intel HD 4600 working
( asked in this thread https://www.tonymacx86.com/threads/guide-lenovo-thinkpad-t440p.233282/page-25)

the system infor show me only 24bit depcolor ( and I see some photo still having switch area transform color, also in window shadow effect )

I've tried to inject EDID but system stuck at boot screen.

attached file:
CLOVER_EDID_true.zip clover with edid inject = true ( system stuck at boot screen)
CLOVER_EDID_false.zip clover with edid inject = false ( Intel HD 4600 working with 1.5GB but only 24 bit depth color)
RehabMan.zip and minh’s MacBook Pro.ioreg.zip ( log collected by tool)


Please help me to detect problem,
thanks very much

Endless spamming of this thread is not helpful.
Clearly, your laptop is different from others here in that it uses eDP, which is not well supported.
You should at least open a separate thread.

I see on this thread
https://www.tonymacx86.com/threads/guide-lenovo-thinkpad-t440p.233282/
, many other people same my machine success with 0x0a260006
why mine is 0x0d220003

as you said "it uses eDP"
It's decided by hardware or bios.
I remember I updated to the latest bios before install osx.

You could always downgrade BIOS to see if it makes a difference.

I updated from official Lenovo site

https://pcsupport.lenovo.com/vn/en/...ies-laptops/thinkpad-t540p/downloads/ds038147
and they also NOTE:
Version 2.28
UEFI: 2.28 / ECP: 1.14

• [Important] Update includes a security fix.
  (Note) If the UEFI BIOS has been updated to version 2.28 or higher, it is no longer able to roll back to the version before 2.28 for security improvement.
