The machine in question is Lenovo T430s. I'm trying to get mDP working.
1 case:
ig-platform-id = 0x01660004
HDMI-video, 64MB BIOS, HD4000 0x01660004 patches = enabled
This results in perfectly working laptop panel, but mDP remains inactive.
2 case:
ig-platform-id = 0x01660003
HDMI-video, 64MB BIOS, HD4000 0x01660004 patches = enabled
This results in perfectly working mDP, but laptop panel becomes garbled (stripes, pink color, distortions).
I do understand, that clover HDMI patches mentioned are incorrect for 0x01660003
Also the Lenovo UEFI does not allow to change VRAM amount. I think there's a problem with VRAM amount and framebuffer patches incompatible.
I've attached all the debug info I could collect + all the MaciASL patches used.
Any help is truly appreciated. Thanks in advance!
