Hi. Gigabyte Z390 UD + i5-9400 HDMI Black Screen Problem (no external graphic). Full description here.

Currently I can achieve only "Intel UHD Graphics 630 7Mb" (no acceleration, hackintool detected connected monitor as external). I have tried different variants, but have no success. Could somebody help me pls ?

I do not have external GPU . Do I need to use ID of mobile version ?

Hi,

I don't know how to find the "pipe" and the "flags", I think this is my problem.

I appreciate the help, or a guide for dummies :)

Hello @andersonlugo

Please edit your post and remove the guide. We should not quote entire lengthy guides.

Pipe and Flags are the 3rd and 5th columns in the screenshot you posted. We don't have to worry about these items though. Just focus on Index, BusID, and Type.

But note that on-board HDMI ports no longer work in Catalina.

On-board HDMI ports no longer work in Catalina. See the large NOTICE at the top of Post #1.

So, there is only this variants for me :
a) Image on screen, but no video acceleration.
b) Use version < 10.15.x
c) No image on screen at all.

Is it correct ?

Correct, but if you have an available PCIe slot, then an AMD GPU would be a good choice.

Hello,

I can not make it work for me, I already tried all the BusIDs and the indexes in a patch .. could someone help me, I have a VGA in the laptop, the acceleration intel HD works. The laptop restarts normal but when connecting VGA there is no video, no signal. :(

When I connect the VGA none lights up.

Could someone give me an idea. I have Catalina.

VGA has never been supported on recent macOS versions (or any?)

I'd suggest plug into that nice HDMI port right next to it.
