This would be a typical configuration to try:Hey! Great info you have here!
I have a MSI H310M PRO-M2 motherboard and i5 8400, the board has 3 ports (VGA, DVI, HDMI). I can only use the VGA port, single monitor in HDMI will blank out when reaching desktop, and when trying dual monitor same thing happens.
I'm using SMBios iMac18,1 (tried 18,3, 19,2, macmini8,1 but they cause all my usb ports to stop working)
I have acceleration, but couldn't find a patch that enables my HDMI port (don't have any DVI to test)
My VGA is at Index 3, works with many Buses and Types no problem.
Tried both Index 1 and Index2 with Type HDMI with Buses ranging from 0x01 to 0x07 and none is able to give any signal
Is there anything else I could do to try and make this work ?
Started with Mojave 10.14.3 and now testing with 10.14.5
Edit: My IGPU is a 0x3e92, I'm using Platform ID 0x3e9b0007
Index 1: BusID 0x02, Type = HDMI
Index 2: BusID 0x01, Type = HDMI
Index 3: BusID 0x06, Type = DP (physical port = VGA)
If none of your attempts worked, could it be that the connector patch was not applied correctly? During each test attempt, you can run IORegistryExplorer then scroll the device tree to "IGPU@2" and click on it. Then on the right side you should see each of the "framebuffer-con0-xxx" and "framebuffer-con1-xxx" and "framebuffer-con2-xxx" entries. If these entries are missing, then the patch has not been applied correctly or is otherwise not activated.
