Some display connections are not working after the colour banding fix about nootedred HOT 27 CLOSED

mini PCs don't really strike me as AIOs either :^)

from nootedred.

I have removed the patch at fault. Sorry for the inconvenience, I hate AGDP.

from nootedred.

I reverted the problematic commit, and will reintroduce the fix properly once I fully understand what I'm supposed to do

from nootedred.

The last commit where HDMI works without problems is 0c15616.

from nootedred.

sudo rm /var/db/.com.apple.iokit.graphics

see if the issue persists, if yes, provide an AGDCDiagnose log using

sudo /System/Library/Extensions/AppleGraphicsControl.kext/Contents/MacOS/AGDCDiagnose

and send it over here

from nootedred.

"sudo rm /var/db/.com.apple.iokit.graphics" didn't help so im sending a AGDCDiagnose log.
AGDCDiagnose.txt

from nootedred.

AGDP printed no frame buffers which means it does not like your configuration, switch to a different SMBIOS

from nootedred.

I use iMac20,1 on all AMD Mini PCs and there has been no problem so far. Why has it worked without problems until now?

from nootedred.

The getVendorInfo patch was broken until now, making AGDC think this is a dedicated GPU.

from nootedred.

Does it help if I send you the AGDCDiagnose log with commit 0c15616 where it still works?

from nootedred.

The getVendorInfo patch was broken until now, making AGDC think this is a dedicated GPU.

Hmm, so what SMBIOS should we be using now if not iMac20,1? The iMacPro1,1 only has dedicated GPU...

from nootedred.

Try MacBookPro16,3.

Try MacBookPro16,3.

So, it doesn't strike me as a good idea to use a SMBIOS of laptop for a desktop.

from nootedred.

bruh ur mini pc literally have a laptop cpu 💀💀

from nootedred.

literally a laptop motherboard shrunken in size

from nootedred.

Try MacBookPro16,3.

Ok, so on the MacBookPro16,3 HDMI also unfortunately does not work :-/

from nootedred.

That's weird.

from nootedred.

Isn't this a similar problem to the Hackintosh with AMD dedicated GPU where you have to use agdpmod=pikera boot argument with newer GPUs, otherwise the computer boots to a black screen?

from nootedred.

this patch is already in place, along with another for making AGDP continue if there's only one FB

from nootedred.

I have Trigkey Mini PC with 5700U and Beelink Mini PC with 5800H and both have same problem with HDMI.

from nootedred.

Look like we need some new agdpmod patch...

from nootedred.

I'm experiencing the same issue over HDMI on my 4700G Desktop, 14.4.1, iMac20,2, commit 2cf2ad6.

from nootedred.

Commit [e450df1] is still not detecting HDMI. [0c15616] is working great.

from nootedred.

what

from nootedred.

With the latest version I have the same problem again - HDMI does not work.

from nootedred.

There have been no code changes for 2 months. That's impossible.

from nootedred.

So I reverted back to the last version again and now it works. I tried it several times before and it didn't work. I don't understand. Sorry for the false alarm.
