I made my own EFI according to the opencore guide, using opencore 0.68, all drivers and kexts are downloaded from the latest, but after booting and selecting system recovery, after running the code, the monitor lost the signal, I don't know if there is something wrong with my config.list settings, I change the model, such as iMac19,1; iMac19,2; Macmini8,1 and other models, the situation is the same, I suspect if it is the interface of the monitor, but I have no more monitors to test.

My monitor only has three interfaces, DVI, HDMI and VGA, while the computer has two DP ports and one VGA port

Because I know macos does not seem to support VGA anymore, I used a DP-HDMI adapter to plug into the monitor
However, after I downloaded this file from olarila to install
https://www.mediafire.com/file/ws7fpljza84ueia/Olarila+BigSur+11.2.raw/file
The signal is output from VGA, but the DP port signal is disconnected

I'm not sure why, but I'm glad I was able to install it successfully.

Today I used opencore0.68 to make a brand new EFI folder to boot the system made by olarila, but as I said before, the screen went black and it seems that both DP and VGA lost their output signals.

I would like to know what the cause is.

Also, after I changed the model to iMac19,1, I used istat menu to check the CPU usage and was able to recognize 6 cores, but the GPU never showed the temperature, just a " - " symbol, I don't know if the cores were not driven successfully, Then I tried to output a video with finalcutpro and found that only 6 CPU cores were involved, while the GPU did not respond. At the same time, the computer became very laggy. I tested it with MacX Video Converter Pro, and it looks like the computer has hardware encoding acceleration enabled, and HEVC is also shown to be active.

The second point is that there is a bug in sleep, when the computer is woken up, the monitor display resolution will change and the display screen becomes very narrow, I tried several tools to modify and fix the resolution, still not working.

The above is what I encountered, I hope I have elaborated the problem clearly. Attached is the file I got with runme.app and the debug file when I made the EFI boot system with 0.68opencore, hopefully it will help me find the cause.

I'm grateful for your help! MaLd0n?

Hi, MaLd0n
Thanks for your quick reply, the attachment is my own EFI made from the open core guide page, and the lilu.kext and whatevergreen.kext I replaced with your EFI, may not be the latest

It is this EFI that causes the black screen on boot

Or, can you help me improve the EFI file you provided to drive the graphics card correctly, solve the problem that the core graphics card does not work during video output, and can use HDMI to input to the display.

Now, although VGA output can be used, as long as it wakes up after sleep, The resolution will drop, the display is not clear, and the normal picture can be restored only by re-plugging the VGA

Please, I follow the official tutorials, and I always have problems, either superIO or a black screen. I have been tossing for almost a month and there is no progress.?

Sorry, my fault, because I can't directly access the Internet and can only use proxy software. It may be that there is a problem with my routine. I just switched to the Japanese routine.

My country can only use vpn to access the Internet. The line I chose may not be able to access the website you provided. I just switched to the Japanese line and can download normally.
