<< Solved >> HDMI not working on HP Probook 440 G4

[batmanlovesuperman]

Hi, I am trying to get my external display to work. I have the HP Probook 440 G4, Intel i5-7200U @2,5GHz, Intel HD 620. When I plug/unplug my monitor via HDMI, my laptop crashes and reboots itself. Plugging the display before booting doesn't work either. Can someone help me to get HDMI to work? Thank you

Thanks, I managed to get HDMI working by reverting to IntelGraphicsFixup

there you go (attached file)
i did a fresh install and used whatevergreen. remember to use the correct ig-platform-id for your IGPU. more info here:

also you might need to fix EDID in case your HDMI signal is YCrCb instead of sRGB

Thank you, but I found another HP Probook 440 G4 EFI folder ...
everything works for me except for the fingerprint
You can try (attached EFI) you might need to use Clover UEFI Hotpatch to install kexts to L/E https://www.tonymacx86.com/threads/...book-zbook-using-clover-uefi-hotpatch.261719/
