Yes, I can VNC into the iTX from the other computer.
If you are able to VNC in to the system, that means it's awake.

How is your monitor connected? HDMI?

Try DisplayPort and/or higher quality cables.

Yes, I am using HDMI. The screen woke properly under 10.15.3 but stopped after updating to 10.15.4. The computer definitely woke but the screen would not without either powering up and down or removing and replacing the HDMI cable. Using different HDMI cables made no difference. DisplayPort works fine.

Any idea why the HDMI output no longer wakes the screen? I even attached a different monitor with the exact same results.
thx

HDMI just doesn't work reliably in macOS. I don't know why. I've tried many different things with spotty results. Best to just stick with DisplayPort.

There's nothing wrong with your configuration.

I haven't tested Mojave, but I think it should work fine.
Tested it today and with EFI Clover r5107 Z390G (Catalina).zip update from 10.14.6 (18G3020) to Security Update 2020-002 10.14.6 (18G4032) went well without any issues.

Thanks pastrychef :)

DRM works with iMacPro1,1. Sidecar doesn't.

Sidecar works with iMac19,1. DRM doesn't. There are imperfect workarounds for DRM but, again, they are imperfect.
Regarding this... for people with an 8700 and a dGPU, is there a difference between using 18,x or 19,x and which do you suggest?

Between iMac18,x and iMac19,x, I suggest 19,x.

Thanks. I'm glad I had a monitor with DisplayPort.

Great, thanks.

I have done some research and not really come to any conclusion so far, which would you suggest is best 19,1 or 19,2?

According to Everymac;
19,2 has the 8700 but a 555X/560X or Vega 20
19,1 has 570/575 or 580 cards, but doesn't have the i7-8700.

Am I right in thinking that the gpu said smbios has is not that relevant, providing it is in the same family (500)?
Therefore for a i7-8700k and RX580, iMac19,2 would be best? Or is 19,1 fine too?

I just use iMac19,1. I've never used iMac19,2 but either should be fine.
