Thanks for quick replay, P1LGRIM,Consult an electrician, nothing that you do on the computer will resolve that problem.
Have you experimented with different Platform IDs and Bus IDs?Hello, I am trying to patch my HDMI based on this guide, on my Dell XPS 15 9560 4k i7-7700HQ, HD630 and GTX 1050 (disabled).
If I plug in the HDMI the built in screen turns black a few times for a couple sec, but in the external 4k monitor I get no signal.
What you should know, that this notebook only has HDMI 1.4 port, so only 4k@30Hz should work. It has an USB-C port also, but I don't have the cables for it.
I have tried whatevergreen enable-hdmi20, disabled-external-gpu, enable-hdmi-dividers-fix, enabled-dpcd-max-link-rate-fix, with no luck. Actually what I always get is a no signal on the external monitor.
The HDMI should work, because when I boot up the system with my HDMI plugged in I got picture only in the external screen, but after logging in, in a few seconds the system reboots.
I attach my clover folder, maybe someone can help.
In the "About This Mac" my graphics show up as Intel UHD 630 as it should. But when looking at the Framebuffer Patching Guide, Step #6, using Hackintool to determine if the proper display patch is being used, I am getting an odd value, "Intel 8th Gen Core Processor Gaussian Mixture Model".
Hello @Thaigyver,@CaseySJ, Great instructional post on Framebuffer Patching. Also, a big thanks to headkaze for Hackintool and jaymonkey for both Lilu and Whatevergreen. I have learned a lot more on my second build.
Second and Current Build:
ASRock B365M Pro 4
Intel UHD 630
I have read through the General Framebuffer Patch Guide a couple times getting ready to give it a go, but I am left with one question from my end before I begin. I did my best to try to find an answer to this on the forum, but I did not find anything. In the "About This Mac" my graphics show up as Intel UHD 630 as it should. But when looking at the Framebuffer Patching Guide, Step #6, using Hackintool to determine if the proper display patch is being used, I am getting an odd value, "Intel 8th Gen Core Processor Gaussian Mixture Model". Pics attached.
If anyone has any ideas why it says that or if it is not important, I would appreciate the help
I have tried using different system definitions, such as macmini8,1, iMac19,1 and iMac19,2. Nothing changes with these different system definitions.
And, just as a side question as I am trying to learn more about using this forum, I have my first system build showing to the left. When I try to add my second build under "Build Signature", you can see that the MB just comes up as "Other". I understand it is not available as a choice as it is not on the recommended parts guide. Is there a way to manually put this information in? I see many members with many different types of build information in their signature.
Some suggestions:Dear community,
This is a long pending display issue, I'm facing since Mojave and now also on Catalina as well.
The monitor blacks out for few seconds, no pattern to it... however, have noticed it also happens whenever any switch in my house is turned on or off... The blackout happens too often while I transfer data between my external HDD as well and I can't do anything else.
My System Config:
Asus Motherboard: B85M-G
VRAM (Dynamic, Max): 1536 MB
Device ID: 0x0412
Revision ID: 0x0006
Memory: 24 GB DDR3
Monitor: BenQ VZ2350 (Using HDMI port, tried other HDMI cables... same issue))
OS: Catalina 10.15.3
All Kexts are updated to latest release: AppleALC (1.4.8), FakeSMC (1800), Lilu (1.4.3), RealtekRTL8111 (2.2.2), USBInjectall (0.7.5), WhateverGreen(1.3.8)
Clover: 5108 (skipped 5109 due to issues as per forum)
Have also attached my config.plist along with Framebuffer, connector & patch screenshots (from Hackintool) to help me for any change in the settings required to fix the issue. Please help me if any further detail is required.
Any help in this regard is appreciated.View attachment 460929View attachment 460930View attachment 460928
@jaymonkey, Thanks for the info and the very quick response. You made this simple and fast.@Thaigyver,
Thats the PCIe device descriptor text which Hackintool scrapes from a on-line PCIe Vendor & Device database.
Quite often the IGPU device descriptor text tends to be CPU generation generic and not IGPU specific.
It's purely a cosmetic issue and very common.
You can set that to whatever you want by doing the following :-
- Open your config.plist in an editor
- Find the "Properties" sub-section of the "Devices" section of the config.plist
- Find the IGPU Device Properties which will be under <key>PciRoot(0x0)/Pci(0x2,0x0)</key>
- Edit the <string> value for the IGPU Device Property "model"
- Set it to something like"Intel UHD 630 Graphics" (make sure that it starts with "Intel")
- Save and reboot
