No worries, yeah my WX4170 is native to the G5 and the VBIOS ROM I have on it seems to be the good one, all the outputs and features work, the HVEC quirk is a MacOS thing, because the feature is there in ioreg, but the OS won't use it.I think that we have wrong connectors in our vbioses and hotplugs keys. I compare all aty GPUs presented in laptop bios, and they are different from mine. So even g4 and d3 connectors are different. The next step of vbios is to compare igpu, NVIDIA and amd vbios connectors, as I think, they should be the same in one laptop but different in other. I was pretty surprised, when discovered that with Windows, igpu is working only on edp and vga (suppose dvi to vga). But hdmi and dp is from aty. But with mine m2000m quadro, all ports was working fine on igpu!!! So proposing you to switch to this thread https://www.techpowerup.com/forums/...mobile-moded-vbios-for-hp-zbook-15-g3.279373/
for modding vbios to get it working like native
And I think that bios won’t recognize acpi instructions of our GPUs as they are not presented in bios. I will insert back mine old gpu to check if mine setup will work fine. Then will compare chipset selected acpi tables to those which are selected with amd.
UPD1.
Sorry for my inattention, your WX4170 is native Zbook gpu. So you no need to hex patch of our vbios, as it is supported by your original bios. Even is injected by your bios. Omg now I am feeling really sorry for my advices to patch vbios rom.
The injected version of the Bios only works if there's nothing in the EEPROM, otherwise the Card's rom takes the lead.
HP's newest Bios release is supposed to include new VBIOS, but it's all encrypted and gibberish, can't find the ROM anywhere so who knows if the new one is any better. Do you know of a way to extract the ROM from the Bios Update?
