Hello dear hackintoshers
I own the 9570 i7 8750 model with 32Gb ram. I do have an issue with the hdmi out and the usb-c (hmdi) tripple monitor connection. Whenever I attach a monitor the laptop display turns black. It is still discovered in the display manager from system preferences.
I'm using bavariancake EFI and I've read that people have it successfully running on the exact same machine. I have found a solution on bavariancake's page:
Enabling external display support
Without any options passed to WhateverGreen, a KP will occur whenever an HDMI device is attached. @0xFireWolf provided HDMI output support (HDMI 1.4 and 2.0) by adding LSPCON support to WhateverGreen.
Up to two 4k@60Hz DisplayPort connections are supported via type C with adapter, and HDMI can also be connected. However, the internal display will turn off if three external displays are connected (see Intel GPU limitation above).
Connector 0 is the internal LCD, connectors 1 and 2 are DisplayPort via type C, and connector 3 is HDMI. The boot argument agdpmod=vit9696 is required to disable board checks, since the MacBookPro15,1 doesn’t have an HDMI output, and would be ignored by the OS by default.
Enabling HDMI 1.4/2.0 and DisplayPort via type C connector
- config.plist
- Boot/Arguments
- Devices/Properties/PciRoot(0x0)/Pci(0x2,0x0)
- framebuffer-portcount = <04000000>
- framebuffer-con1-enable = <01000000>
- framebuffer-con1-alldata = <01050900 00040000 87010000>
- framebuffer-con2-enable = <01000000>
- framebuffer-con2-alldata = <02060900 00040000 87010000>
- framebuffer-con3-enable = <01000000>
- framebuffer-con3-alldata = <03040a00 00080000 87010000>
- enable-hdmi20 = <01000000>

- framebuffer-con3-has-lspcon = <01000000>
- framebuffer-con3-preferred-lspcon-mode = <01000000>
I tried to change all the entries as above in the config.plist but it resulted with only one external screen to show up. I am sure I must be not far from running that 9570 with the 3 monitors on. Can someone explain me what I should do have both usb-c out (hdmi adaptor + the regular hdmi with a working monitor out signal.
Thank you in advance
