I have a problem on Z370N with i5-9500T. I copied the patch from the first page of this tutorial. After waking from sleep, my screen does not turn back on. It's turning on after every second wake only. I connect with VNC to see what is going on. Resolution is correct and everything works, just...

macOS 10.15.4, iMac18,1. I didn't test the DisplayPort, I don't have a cable.

Hello. I know, that currently it is impossible to get sleep/wake functionality using just Intel HD530 and HD630 Graphics cards. I would like to gather as much of knowledge of this problem as possible, so please share all you know / think about this. Also if something Im writing is wrong, please...

I can't make it work on Gigabyte z270n Gaming 5 with i7-7700T. Always black screen or no acceleration. I use 00001259 as platform. Anyone has similar CPU and made it work? there is no dGPU in the system, just iGPU HD630

Good to know there are others trying as well. Lets keep in touch if we can find anything. Im also trying with HD630 on i7-7700T. I have tested both Clover and OpenCore, the same issues. For some time I have had slightly different results, but Im not sure what caused this - system was actually...

From what I know sleep/wake on HD530 is unreachable. I have also spent a lot of time trying to fix this but with no luck, and all I have found was information that it can't be done. I read somewhere, that is should work with HD630, so I swapped CPU (sleep is also kinda important for me), but...

Interestingly, in Catalina after sleep, my system wakes up for few seconds. Its working normally, I can open new apps, etc, but after just about 5 seconds it reboots. Maybe it could be a little step forward?

I did add these numbers, I just selected iMac17,1 again and numbers were added Here's my current config, I must have change just a few settings in ACPI. Maybe someone can find something. Again - its i9-9900K, so slightly different CPU, but still coffee lake refreshed. Maybe we are missing some...

For me it's still the same - black screen after system loads :/. You use HDMI right?

Thats right, I tried with iMac17,1 too. Changing to 0x59120000 is also not helping, still no acceleration :(

Didn't work :/ Here's my EFI - now system reboots while loading, when it supposed to show desktop

Im trying, but Im getting no acceleration :/ Please check my config from picture if I used these values correctly

Could you please upload config.plist with serial removed? I would like to see what other options should be configured and test it too. Im trying like on image attached, but I get no acceleration :/

Please let me know in this thread if anytime you find out something new. I'll be buying external GPU anyway, but it would be nice to have this working too.

Update didn't help :(

Oh, I'll try to update then. I don't think it will help, but who knows.

I'm trying to fix uhd640 on i9-9900K with Mojave. First it didn't recognize video card, and acceleration was not working. This was fixed by inserting device-id 913E0300 and AAPL,ig-platform-id 07009B3E, but now I have no video output from HDMI - monitor is off. How can I make it output to HDMI?

Thank you for the answer. About this HDMI this is exactly the problem I have. Acceleration works with the values you provided, as with the previous ones, but there is no HDMI signal. Is there anything I could do to make it work? Maybe some ports needs to be activated/redirected somehow? Also now...

What values should I use for i9-9900k? I tried these from 8 gen, but I’m not sure if these are right. Also when I do this I get no signal from HDMI

Hi. I have build a hack on Gigabyte z390 Aorus Master with i9-9900K. I can't get HDMI signal, only black screen. I know system is working, I can connect to it with TeamViewer. iGPU is displayed as "Intel HD Graphics CFL CRB 1536 MB" is that correct? Can you help me somehow fix this to get HDMI...
