[FAILURE] Monterey on HP Compaq Elite 8300 All-In-One

[HarFanG]

These above are Monterey ones, But guess what ? Yesterday evening, I got the system destroyed. Over beyond recovery. Doesn't matter, I don't care. LoL.

So, I removed the crashed HDD and replaced it with a SSD. And started the whole installation mess again (should be the 7th, not counting Big Sur ofc). = Monterey !

Eveything went fine to the desktop on the HQP 8300 : haha, 1280x1024.
I did a TIme Machine backup, just in case of.

I can tell for sure, that the HQP is not seen as it should be : its EDID is not here.
Following FB tutorial, I started to play with CON0 : con0, con1, con2 and con3, one at a time.
See the 4 snaps attached.

Then I did the Chris1111 HD4000patch. As soon the system rebooted, it lost the HPQ...
So, I used power switch, connected Acer G245H and restarted.
As each time I did it, all went fine until coming to the desktop : HQP turns black, and desktop is displayed onto the Acer....
In practical terms, I'm back to yesterday's configuration befor the fatal crash.

I hope you're having a good laugh, thanks to me. ROTFL !

Joking put aside, I'm stuck with BusID, PortID, with all that crap...
One stupid thing (among others) : does the HQP has to be defined as "internal" ?

Last, the 5th pic : Port5 has HQP, Port6 has Acer. I CAN'T EVEN SET THIS UP DAMMIT !!!

Look, I spent 4 weeks on this sh!t, I'm bored to death... This AIO sucks.

Don't worry. Attach the EFI you're using to boot now and for everything to be better, highly suggest you to use Big Sur until the display issue is fixed.

Ok, I spent another 2 hours in it, and I found a new issue

This is the last EFI I made. Ofc, as I'm a real n00b, there are lots of "checked items", just wanna disable them (temporarily or not).
I just noticed this :
- if I'm not overriding HQP's EDID, there's only the Acer showed in Hackintool. HQP keeps staying black. The whole system runs fine ;
- If I use override HQP's EDID, both screens are show in Hackintool. HQP stays black again. The whole system runs fine, EXCEPT it crashes on reboot/switching off...
I mean : Acer goes black, the mouse stays on screen, frozen => needs a power off.


EDIT : added IOreg with HQP EDID injection and without if that can help.

Your whole Framebuffer patching is wrong!

It's no surprise, why it isn't working

Here's what you need to do.

Delete all the DeviceProperties entries
Add -igfxvesa in boot args.
Do a clean install of macOS Big Sur.

Then, we can do things seamlessly, rather than putting efforts in the wrong direction.

 

[HarFanG]

I understand, but...there is no harm to keep uneeded entries in config.plist, as long they're disabled, OC will ignore them.
=> AAPL, device 0x2 will work.
=> ##AAPL, device 0x2 won't do anything.

But ok, I'll take a chance with removing all entries in DP as you suggested, thanks.

I'll forget to try again with -igfxvesa, will try, thanks.

Big Sur ? Why ? I'm still on Monterey.

 

[HarFanG]

I re-installed Monterey and used “igfxvesa” as you said.

On the desktop, the HQP screen only displays 1280x1024.



Then I patched with OCLP.

With “igfxvesa”, there's no graphics acceleration and the HQP works, but no bigger than 1280x1024.

And Hackintool says: “monitor unknown”.



I'm back where I started...

Okay, you're more qualified than I am, so I did what you just said.

- removed all the options in Device Properties ;
- added -igfxvesa to “boot args” ;
- installed Big Sur 11.7.10;

All went well:

- audio works;
- integrated microphone too;
- the built-in screen (HQP) displays the desktop;
- is detected as 23 inches (which is correct);
- but goes no higher than 1280x1024;
- is seen as "unknown monitor model".

I shut down the machine without doing anything else.

Big Sur because it has native support for your GPU and the patching can be more easier.

You were supposed to install Big Sur!

Now, that's nice!

Now, attach the following in a single Zip file.

- EFI
- IOReg
- Hackintool Info+PCIe Info
- System Report
- Kextcache output
- Use the latest DarwinDumper and provide the output

Do NOT use your external monitor for now.
