No worries! Thank you for hanging in there with a noob. I applied the new config. And, this weirdness happened.
(This is with both monitors plugged in)

Funny thing is; I came to the same conclusion and, tried to do the same thing you described... But, it seems to pretty much ignore what I want it to do... instead, opting for what it WANTS to do. Just like the above screen grab.

This config results in a black screen on HDMI and DP until I log in blindly. After this, HDMI will light up. But, DP will not. But, again DP is recognized in System Profiler as 4K@30Hz. When I try to reset it using System Preferences --> Displays --> Gather Windows --> ... The DP monitor is back to showing only a text box with "low resolution" options.

BUT, this is the first time in a while that I have seen both a DP and HDMI display in Hackintool.

???

New Post vs Edit advice... noted. I did not realize that. Thanks

When you click on the red row, you will see a port number stated on the bottom right of the Hackintool window. Can you please report that number when HDMI alone is plugged, and again when DP alone is plugged?

Here are the screen shots of Hackintool.

With ONLY DP connected.

and, with ONLY HDMI Connected.

So... They are trying to use the same resources?

I will be offline until tomorrow as it is already midnight and, Saturday is a workday for me.

Thank You! Be back tomorrow.

Hmm, something is fishy... I am grabbing coffee at a nearby café so will look into this shortly. Meanwhile try powering down, disconnect power cable from the wall for 10 seconds (yup, no joke), reconnect and reboot. Do you get any different results?

Hi @CaseySJ. Thanks for helping @HackinMax with this frame buffer problem. I’m learning a lot from your posts from the sideline.
Question though, can the UHD 630 drive two 4K@60Hz monitors simultaneously? Ie does it have enough frame buffer memory to do this and can it be extended to 2000MB as per the Hackintool guide by Headkaze?

Yes I believe it can, but with the following conditions:

HDMI must be v2.0 for 4K60. Most motherboards have HDMI v1.4 that is limited to 4K30.
DP 1.2 or higher.
Not sure whether we really need to extend VRAM to 2048MB.

The Gigabyte Designare Z390, for example, has:

HDMI v1.4 limited to 4K30.
DP 1.2 via Thunderbolt 3 USB-C that supports 4K60. (1 of 2)
DP 1.2 via Thunderbolt 3 USB-C that supports 4K60. (2 of 2)

So dual 4K60 support from the iGPU is only possible with the use of both of the Thunderbolt 3 (TB3) ports.

One can also connect a Thunderbolt 3 Dock that has two DP connectors on it in order to avoid tying up both of the on-board TB3 ports.

Thanks for that info. I have a TB3 to 2 x DP adaptor that I will try once my Titan Ridge arrives. Thanks again.

Done.

Unfortunately, everything is exactly as my previous. Fishy indeed.

Keep in mind that I switched to the MacMini8,1 SMB at V2. Video is eminently more stable when working.

Attaching my config.plistjust in case I may have done something wrong with pasting your patch.First image is when HDMI only connected.
Second is with DP only connected.

Several things to try:

Let's use the attached Hackintool 1.7.6 instead
Also attached is slightly modified config.plist; nothing really wrong with yours, but let's try this new one
Also please check version of Lilu and WhateverGreen by right-clicking and selecting "Get Info"; are they 1.3.1 and 1.2.6 respectively?

Lilu 1.3.1.RELEASE.zip
https://github.com/acidanthera/Lilu/releases

WhateverGreen 1.2.6.RELEASE.zip

Used the provided plist and updated to most recent WeG 1.2.6 (from 1.2.4) and Lilu 1.3.1 (from 1.2.9)

The first screen here is with HDMI plugged in (Booted screen)

This screen is when DP is plugged in and HDMI disconnected

System Profiler with BOTH monitors connected. (Actually HDMI was hot plugged back in.) DP monitor goes black. But, is still recognized in Profiler... albeit @30Hz

The IOReg file shows that DisplayPort signal (type 0x10) is present on Port 7, which is Index 3. So Index 3 is actually DP. HDMI signal would be 0x08.

Screen Shot 2019-01-19 at 2.49.05 AM.png

That leaves Indexes 1 and 2 for HDMI. Let's first assume HDMI on Index 1 (port 5). The attached config.plist V7 makes the necessary changes.

However, please also download gfxutil from here:
https://github.com/acidanthera/gfxutil/releases

And run this in Terminal as follows:

Code:

$ ./gfxutil -f IGPU
DevicePath = PciRoot(0x0)/Pci(0x2,0x0)  <-- do you get exactly this?

Also ensure that "Apply Current Patches" is checked on in Hackintool.
