Anyway - there is even no id for my igpu in WhateverGreen - so it is miracle that i am able to use my 4k dp monitor and laptop screen ( not both at the same time ))
my fault - i do not use built-in screen since it is too small for my eyes - so i did ioreg when connected to 4k external by type-c-DP adapter and closed lid.Some questions and comments:
- Are you running latest version of macOS Catalina (10.15.4 + supplemental update)?
- Is the laptop currently connected only to its built-in LCD screen?
- When you posted the IOReg file, were any external monitors connected?
- According to IOReg, there are 3 video ports:
- Port 0 (internal) -- Connector Type 02 00 00 00 --> reverse bytes --> 00 00 00 02 or 0x02
- Port 5 -- Connector Type 00 08 00 00 --> reverse bytes --> 00 00 08 00 or 0x800
- Port 6 -- Connector Type 00 08 00 00 --> reverse bytes --> 00 00 08 00 or 0x800
- Your monitor was connected to this port (port 6) when you captured the IOReg file
- Is this the built-in monitor or an external monitor (connected to USB-C)?
No problem.my fault - i do not use built-in screen since it is too small for my eyes - so i did ioreg when connected to 4k external by type-c-DP adapter and closed lid.
if neede i will attache build-in only ioreg
- catalina 10.15.4 - last ordinaty update
Because we only want to change Index 1, we can omit the other entries. I've modified your config.plist accordingly, but BusID is still 0x05. It would be good to try all other BusIDs one by one.i have only tried Index 1: Type HDMI, BusID 0x04 and all others with index 2
Please check attached config if i do it right.. Thank You
Is HDMI working with BusID = 0x01?wow - Index 1: Type HDMI, BusID 0x01 - is my HDMI !!
LOOKING FORWARD TO TRY ALL 3 PORTS TOGETHER.. but do not believe it will work)
Sorry - remove other indexes from where ? i have 0 for built-in 1 for HDMI 2 for DP and FFFFF for con3 in propertiesIf so, try removing all other Indexes (Index 0, 2, 3). It's not necessary to include all of them unless they need to be modified.
