pastrychef's Asus ROG Strix Z370-G Gaming (WI-FI AC) build w/ i9-9900K + AMD 6600 XT

Hi,

I have an odd problem regarding the monitor output. I have two graphic cards as described in the signature. The AMD card is in slot #1 and connected to the monitor via HDMI, and the nVidia card is in slot #2 and connected to the monitor via DP. I have disabled the nVidia card from config.plist using devices properties. Things work well for both macOS and Windows.

But whenever the monitor go to sleep or being turned off in macOS (just the monitor, not the whole system), I can't get it to turn back on. HDMI has no output. I have to shuffle the monitor cable (switch DP cable from the nVidia card to AMD card) to get some sort of monitor output.

Any idea what I have done wrong here? It seems like a trivial problem.

I've never had much luck with HDMI on macOS. It often wakes to black screen or flickers in the middle of normal use. The same HDMI cable on the same computer with same video card works fine in Windows. In some instances, lowering resolution and/or refresh rate helps.

If possible, use DisplayPort instead of HDMI.

I see. The thing is, my monitor only has 1x DP and 1x HDMI. And 144hz only works through DP port in Windows.
I guess I just have to live with it.

Sometimes, higher quality HDMI cables can help.

Do your problems manifest when using DisplayPort with macOS?
 
No. There's absolutely no need to do that at all. It's just a massive waste of time.

  1. Download the OpenCore EFI.
  2. Plug in your Serial, Board Serial, UUID, and MAC address to the OpenCore config.plist.
  3. Replace the EFI on the EFI partition of your main system drive (or put it on the EFI partition of a USB flash drive if you want to test first).
  4. Reboot.
Really? That's -all- there is to it? What about all the carefully selected drivers and kexts I currently use with Clover? Obviously I'm missing something here...

kexts will belong in the kext folder

Edit:
they will also need to be listed out in your config.plist
 
OK: the thing I'm missing here is that I've not actually looked at OC, although I'd like to since that's the way things are going. So: is there also a driver folder? Sorry to be so obvious... has someone done a tutorial here on switching from Clover to OC? I can go read that instead of asking dumb questions...

when you download OC, you will see a sample.plist which will give indications of the structure

there will be a lot of studying to do, trial and error etc
 
OK. Thanks. I thought OC was still in the experiment's stage and not yet ready for the mainstream. I just barely got Catalina stable on this rig, and really don't want to spend two more weeks mucking about. That's why I was surprised at the seeming simplicity of that previous post.

I'll wait until it's ready for prime time.

Thanks again.

Since you are on a different motherboard, you may need different SSDTs, drivers, kexts than what is needed for the Asus ROG Stryx Z370-G Gaming (Wi-Fi AC). So, the OpenCore EFI attached to post #1 will probably not work for you as-is.

That being said, once you've made the proper changes to adapt the OpenCore EFI to your motherboard, the above steps are all that's needed to switch to OpenCore.

Ah... yes: of course. Reading your post at 9159 I didn't realize you were talking about a specific upload of a configured EFI when you said "Download the OpenCore EFI." I thought you were referring to a base copy of OC. So I got confused.

Thanks. Like I said, I'll let things stabilize, or wait for Clover to finally die, before I spend the time to switch over. As they say "If it ain't broke..."
