Wrong platform ID for a desktop, therefore no QE/CI

Change to

AAPL,ig-platform-id = 00001259

You can leave out device-id

@Jake Lo Actually I attached the wrong config.plist file. The one attached above gives the correct color but the one that I attach here with the correct platform gives the wrong color. The IOReg for the display is incorrect and cannot identify the correct display device.

config.plist.zip

 

@Bronxteck I tried that but no effect. One strange thing is that if I use screenshot to save the screen the resulting image gives correct color.

hmm, according to Dortania, you should use

AAPL,ig-platform-id = 00001659

 

it's what you have but you have the numbers reversed

AAPL,ig-platform-id = 00005916

@kcmok Please note that hexadecimal values specified as DATA in properties injection must be entered in reverse byte order. So, if you want/need to inject graphics framebuffer layout 0x59160000, you must enter value 00001659. It is read byte by byte, from right to left: 59-16-00-00.

@Jake Lo When I accidentally reversed the number to 00005916 I got the correct colour. But if I used correct platform ID, I got the distorted colour as shown in the first post. The second config.plist attached is the one I got the distorted colour but IOReg results did show correct display info.

Do you have access to DVMT in the BIOS to set the minimum requirement to 64MB?

If not, you'll need to add these

  • framebuffer-stolenmem
  • framebuffer-fbmem
  • framebuffer-patch-enable

I did add those 3 lines with values according to Dortania, but same colour distortion. If I use the incorrect platform ID and get the correct colour the display info is incorrect. The 24” dell monitor cannot be identified and interpreted as a 31.5” display
