HDMI output does not work

[eamigo86]

Hello everyone, I am looking for a publication that indicates how to solve the problem for the use of the HDMI port after the hackintosh process for this specific laptop.

These are the advances that I have achieved at the moment:

1. Audio, no sound through internal speakers, although headphone jack are working.
2. Sometimes, Sleep action turn off the screen into a black screen and not wake up, and I have to restart by power button.
3. It do not save the screen brightness level setting, when starting it is always at 75% or 80%.
4. The advanced gestures of the trackpad do not work except the scroll with two fingers.(Fixed except "Smart Zoom" and "Notification Center" gestures).
5. Fingerprint sensor, wifi killer card and card reader not work (I have wifi by TP-Link TL-WN823N usb adapter).
6. I can't find any option to change the behavior of function keys, to use default F keys without Fn key.
7. Touchscreen does not work, I have not found anyone commenting on how to put this feature to work. (Fixed, but I can not perform actions other than: select an icon, click or select a icons group)
8. HDMI port for audio and video output.
9. USB-C (Thunderbolt port) not working, for HDMI output.

Thanks in advance

See this thread for update on the HDMI out issue:
https://www.tonymacx86.com/threads/fix-coffee-lake-intel-uhd-graphics-630-on-macos-mojave-kernel-panic-due-to-divide-by-zero.261687/

The fix that makes the internal display work likely causes HDMI out not to work, so we'll have to wait for a proper fix.

hi @bavariancake !! we've found a solution to get hdmi working with usb-c hub.
We just need to change board-id in smbios for that:
Mac-27ADBB7B4CEE8E61

I've tried it and it works :)

The next step is to fix the hdmi output without hub/adapter.

BTW, do you know how to config the hd630 to have 2048mb of vram instead of 1500mb? I've tried to boot with another config.plist (I found it in another thread), and after boot with 2048mb of vram, the geekbench4 gives me 21500 score in opengl instead of 20200 score (with 1500mb).

Mac-031B6874CF7F642A
Sleep and wake ,display is opened normally,but I haven't test DP sound output to display when DELL E2417H has no speakers.
