HP Elitebook 850 G6 - Intel UHD 620 - No HDMI Out

[lucyjess]

Hi Guys.

Im hoping im able to get some assistance with this one, Im also new here so apologies if Im posting in the wrong area but I was sure to check.

HP Elitebook 850 G6
Intel i7 8565U (Whiskey Lake)
Intel UHD 620
Catalina 10.15.7

I have had some success getting the GPU working with this guide https://elitemacx86.com/threads/intel-uhd-graphics-620-630-on-laptop.207/ so thanks for that, although I am unable to get the HDMI Out to work, when I plug in a cable it displays no signal. I've tried a few different things but if im honest I am a little lost now. I have attached a copy of my EFI Folder if anyone wouldn't mind taking a look and perhaps pointing me in some directions to try!

Well, that's already covered in FAQ. However, you'll need to attach a copy of the following

IOReg
Kextcache Output

I have attached what I believe is required apologies I didn't check the FAQ I thought I had read through it all.

Here are some hints.

• SSDT-EC and SSDT-USBX shouldn't be used together.
• SSDT-PNLF should be used from Rehabman. If you're using from somewhere else, GFX0 must be changed to IGPU.
• BIOS isn't relevant for your hardware. Consider removing it. With AptioMemoryFix, you shouldn't use "EmuVariableUefi.efi."
• Use either VoodooPS2Controller.kext or ApplePS2SmartTouchPad.kext. Never both.
• AHCIPortInjector.kext should be removed.

Firstly, you should work on the main issues related to GPU, Brightness and Audio implementation which has a slight impact on HDMI. Although, for a working HDMI, Framebuffer patching is required.

I have created a new installer using the guide for Catalina, although when it boots into clover, it doesn't give display the Install Mac OS Catalina Option im confused as to why because when I did it with unibeast for my first install it worked.

Any picture for the issue? Here, we do NOT use Unibeast or other third party tools.
