Fix Pink Screen on Intel HD and UHD Graphics on macOS Sierra and Later on Desktops [Clover/OpenCore]

An EliteMacx86 Exclusive Guide - This guide covers fixing the pink screen on Intel HD and UHD Graphics on macOS Sierra and Later on Desktops.

Overview

---

Some users are having an issue of the pink screen after fixing their Graphics. This guide will fix the pink screen on your Hackintosh. This fix is for Hackintosh users who are having one of these above Graphics.

Before you start with this guide, get to know about the real issue. After fixing the Graphics, the QE/CI is available and the Graphics works. But the issue is the screen is totally pink and some lags and artifacts are there. This is happening with the HDMI connection.

In my previous post, I mentioned the fix which was to change the SMBIOS. Another fix was to use an RGB forcing method. However, both the fixes work and you get rid of the pink screen but the method doesn't seem solid to me.

When diving deep into the issue, I found what the exact issue was. When connecting HDMI, the connector is listed as a DP port. That's the cause of the pink screen. Once you change it to HDMI, the issue will be fixed.

The following Intel GPU is supported

• Intel HD Graphics 530
• Intel HD Graphics 540
• Intel HD Graphics 550
• Intel HD Graphics 630
• Intel HD Graphics 640
• Intel HD Graphics 650

Requirements

---

Graphics	Any of the above Supported Intel HD Graphics.
Kexts	Original Graphics kexts in S/L/E.
macOS Version	macOS Sierra or later.

So assuming that you've fixed your Graphics, follow the steps below.

STEP 1: Checking Connectors in IOReg

---

1. Open your IOReg and type IGPU in the search bar. Sometimes, the IGPU node is available as GFX0. If the GPU rename has been done, it will be available as IGPU. If not, GFX0.

You should see something similar to the attached screenshot.

2. Once you have located the IGPU node, you can clear the search to get the complete node info.

3. If you check, in the above screenshot, we have some AppleIntelFramebuffer connectors listed. You need to locate your current connector which is driving your display. A simple way to find this out is to find the connector having AppleDisplay properties with display 0 sub-node. In our case, it is AppleIntelFramebuffer@2. Your system can have a different one. Make sure to locate the connector which drives your display and the idea to find it out is a connector having AppleDisplay properties.

4. Select the AppleIntelFramebuffer@2 from the left pane and you'll have the connectors and other properties and info listed.

5. If you check, in the above screenshot, we have some AppleIntelFramebuffer@2 selected. Now you need to find the value for the "connector-type" property. The above screenshot has a property of "<00 04 00 00>". This is the current connector type set originally. The connector type can have different values which are listed below.

Connectors	Value
Display Port	00 04 00 00
HDMI	00 08 00 00
DVI	04 00 00 00
LVDS (For Laptops)	02 00 00 00
Dummy port	01 00 00 00

So we are using HDMI but the connector is defined as DisplayPort which is the actual cause that I also mentioned earlier. We can use WEG's patching feature to change the connector type.

STEP 2: Changing the connector-type

---

All we need to do is to enable the port to which the active display is connected which is AppleintelFramebuffer@2 and then set the connector-type to HDMI resulting in fixing the issue.
Following are the listed properties which will be used in Devices/Properties in config.plist.

• framebuffer-conX-enable = 01000000
• framebuffer-conX-type = 00080000

Note: You need to replace the conX with the value of the Framebuffer which can be obtained from the AppleIntelFramebuffer@ whatever digits you have. In our case it's Apple IntelFramebuffer@2 means the conX value is 2.

The modified properties will be the following

• framebuffer-conX-enable = 01000000
• framebuffer-conX-type = 00080000

Upon replacing and making the entries in your config.plist, it will look something like this. To make it clear, i've highlighted the entries.



STEP 3: Restart your System

---

1. After making the changes, save your config.plist and restart your system. The pink screen should be fixed now.

To confirm these changes, open your IOReg again and look for the connector-type with the active display.

Now you will notice that the connector-type has been changed from <00 04 00 00> to <00 08 00 00> meaning from DisplayPort to HDMI.

Files:

• For Clover, compress EFI/Clover, exclude the themes folder.
• For OpenCore, compress EFI/OC.

Notes:

• Do not include the complete EFI folder.
• Put all files in a folder with your name, compress files as Zip and attach files using site attachments only.
• Do not use any external links.

This worked for me with great success and cheers and happiness. Unfortunately after another reboot a very bizarre and as yet unresolved issue occurred. The display 0 sub node has disappeared. Now post boot the login screen appears and disappears. I can still use Screen Sharing.app to access the new pc however both HDMI and DP are showing the blank screen after boot up. I have been unsuccessful in obtaining a screen shot of:

• DPCIManager/Status

Intel HD 630
Catalina 10.15.6

After adding the 2 lines in OpenCore I'm still getting the pink screen on the monitor and the laptop screen has black around the edge.

This is only applicable on Desktops. For Laptops, complete Framebuffer patching is required.

I have done these steps. The value for connector type is also correct: 00 08 00 00

Yet, the screen is pink. I am attaching my EFI folder.
