Rappel du premier message :

Installed MacOS using the HP ProBook EliteBook Package Creator. Everything works fine except for HDMI video output.
Previously, with previous installations, I entered the ig-platform-id parameter for Intel HD 4000 in Clover:
0x01660003, 0x01660004
ID 0x01660003 led to the appearance of an HDMI signal, but half of the image is displayed on the main screen of the laptop.
ID 0x01660004 displayed a normal main screen, but no HDMI output.
Now, when changing the ig-platform-id parameter for Intel HD 4000 in Clover, the video card does not work normally (it only uses 3 MB of memory instead of 1536 MB)
Please advise what can be done.

HDMI does not turn on (
I don't want to reinstall the system now, a lot of work.
Thank you for your help. Next time I install I will use the new config.plist

Ok. Try OpenCore next time.

I have a custom efi for Mojave.
If you want, for the sake of interest, you can try. It takes 5 mins to replace the efi folder and if something is wrong, then roll back to yours )))

У меня под мохави есть кастомное efi.
Если хочешь, ради интереса, можно попробовать. Делов на 5 мин - заменить папку efi и, если что не так, потом откатиться на свою )))

Попробуй, как эксперимент. Ради интереса. Там всё намешано но работает.

NVRAM перед этим почисти.
Dont forget clear nvram.
