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 of pink screen on Intel HD and UHD Graphics on macOS Sierra and Later on Desktops.

Overview


Some users are having a issue of 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. The another fix was to use a RGB forcing method. However, both the fixes work and you get rid of pink screen but the method doesn't seems 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 pink screen. Once you change it to HDMI, the issue will be fixed.

The following Intel GPU are 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

GraphicsAny of the above Supported Intel HD Graphics.
KextsOriginal Graphics kexts in S/L/E.
macOS VersionmacOS Sierra or later.

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

Checking Connectors in IOReg


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 like in the attached screenshot.

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

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 just 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 connector having AppleDisplay properties.

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

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 current connector type set originally. The connector type can have different values which are listed below.

  • <00 04 00 00> - DisplayPort
  • <00 08 00 00> - HDMI
  • <04 00 00 00> - DVI
  • <02 00 00 00> - LVDS (for laptops)
  • <01 00 00 00> - Dummy port
So we are using HDMI but the connector is defined as DisplayPort which is the actual cause which i also mentioned earlier. We can use WEG's patching feature to change the connector-type.

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.

Restart your System


After making the changes, save your config.plist and restart your system. The pink screen should be fixed now.
To confirm thee changes, open your IOReg again and look for the connector-type with the active display.
Screenshot 2019-11-26 at 4.57.21 PM.png

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.

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:

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.
