But I have lilu and whatevergreen in my l/e folder. It just doesn't load. Is it because I used thunderbolt to connect my gpu and monitor? The only way to login macOS with a lg 5k and GTx card is use one display port cable to login macOS with a black screen then plug in the second display port to light up the screen.

I installed them again still not loaded. Can't find it under ioresources.

IOReg does not show the kexts installed, that is the first problem to solve

No. As the note says: "NVCAP configures all connectors". Do not touch

IOReg screenshot is useless. Useful, attach IOReg
Install kexts, restart, reply with new files

HD530 HDMI audio requires working onboard audio. See Post #1/I. Before You Install HDMI Audio/3. AppleALC.kext ...
Onboard audio, off topic
Just thought I'd note that I found the fix. I had saved a downloaded copy of AppleALC and Lilu to my temp folder for Kexts. I downloaded current versions of both, reinstalled them and did a permissions repair and finally I have sound!

For a display with both inputs, switch from DP2HDMI or HDMI2DP, same as hot plug.
Video shows hot plug, Nvidia driver problem.
Hello, I am currently using WebDriver 387.10.10.10.40.105
Can I upgrade to WebDriver 387.10.10.40.113 to solve this problem,
Is this a common problem?
thank you

couldn't get it back with your guid.
Did not use the guide from this thread. IOReg shows nothing from Post #1 is installed
cloverALC patch
cloverALC is deprecated, was not used for onboard audio and does not install HDMI audio

Make a bootable backup and USB/Clover booter
NvidiaGraphicsFixup.kext is deprecated
Lilu.kext is so old the version is not noted
Remove EFI\CLOVER\kexts\10.13\all kexts and SSDT-HDEF-1 (useless, not applicable to x99)
Update Clover
See AppleHDA Realtek Audio/Post #1/X. Uninstall AppleHDA Realtek Audio/2. MultiBeast ... and II. AppleHDA Realtek Audio Methods/A. acidanthera/AppleALC
Verify ALC1150 audio working
Remove NvidiaGraphicsFixup.kext and SSDT-HDMI-NVIDIA-PEGP@1 (useless, not applicable to x99)
See Post #1/II. AppleHDA HDMI Audio Methods/1. AMD/Nvidia/Intel - acidanthera/WhateverGreen
Restart, reply with new files
