I have a Legion Y530 laptop and installed Hackintosh for the first time.

Specs:

CPU: i7-8750H RAM: 16GB DDR4 GPU: Intel UHD 630 & NVIDIA GeForce GTX 1050Ti (disabled).
I am on macos Catalina 10.15 (19A583)

Acceleration is fully working. I am using the MacBookPro15,1 SMBIOS.

My problem is the following: My HDMI and USB-C ports do not give any video output. After connecting HDMI, monitor displays No Signal. After connecting USB-C(USB C to HDMI adapter) same happens.

Does anyone have any idea what I can do to at least make one of my ports work? Tried different SMBIOS (MacBookPro14,1) and others but didn't work out. In system report under USB Device Tree - USB 3.1 Bus - USB C Video Adapter is detected but no output to external monitor.

External monitor: HP 24es Model: T3M79AA

have you followed the official whatevergreen IntelHD manual ?
I had similar problem on my core i5-8265u (HP Probook 440 G6) and finally fixed the issue, all ports are working now.
But I had to switch from 3EA50009 which worked in 10.15.4 to 3EA50000 in 10.15.5 as 3EA50009 stopped working in 10.15.5 all of a sudden!
check out the following guide but beware what Casey mentioned here:
I haven't been following the thread lately may there are updates already

Yes, I tried all the work around with frame buffer patching from guide. It didn't work. HDMI is not onboard, it is attached with NVIDIA Graphics. So my only option is now USB Type C Video Adapter (USB C - HDMI). Is there any way to fix this ?
