Do you know if you have the older or newer LG UltraFine 5K? I think the newer one has Titan Ridge controller inside. You should be able to see the Titan Ridge controller in the output of ioreg in macOS or in Device Manager in Windows.
Please run the following commands in macOS when the display is running at 5K and when it is reset to 4K.
Change the file names for each output file and post the results. The commands will show how the display is connected to the GPU.Code:/System/Library/Extensions/AppleGraphicsControl.kext/Contents/MacOS/AGDCDiagnose -a > AGDCDiagnose_a.txt 2>&1 system_profiler SPUSBDataType SPThunderboltDataType SPPCIDataType > system_profiler.txt
I have the older LG UltraFine 5K.
Here are the results of the commands. Running the system_profiler command gave me the following message: "system_profiler[581:12249] SPUSBDevice: IOCreatePlugInInterfaceForService failed 0xe00002be" but log file contain USB informations.
Thank you.
