Are you ready for some bad news??
Your ghost display problem triggered an old memory about a similar phantom display problem with someone's PowerColor AX RX 580. When I say "old memory" I mean March 23, but it seems so distant.
@tholstro first reported this problem. At this time we didn't know the source, but after some experimentation we determined it was the RX 580. Because he was within his return window, he replaced the card with one from Apple's recommended list (perhaps Sapphire Pulse RX 580).
The culmination of the saga is described here.
Here are my suggestions:
- You may either exchange the card for a Sapphire Pulse or try the following experiment (requires purchase of 2 cables).
- Physically remove the RX 580. Be sure to fully power down the system (pull power cable from the wall) and flip the plastic retaining clip from behind the long PCIe slot.
- Use two USB-C to DisplayPort cables (such as this one). Connect the cables to each of the two Thunderbolt ports on the Designare, and the other ends to your two monitors.
- The Intel UHD 630 IGPU can easily drive two 4K monitors at 60Hz through the two USB-C (Thunderbolt) ports.
- Do you see ghost or phantom displays?
- Then disconnect the USB-C cables, install RX 580, connect monitors through RX 580, and see whether phantom displays come back. (They should come back.)
- This will confirm that macOS itself is okay, but the RX 580 may be the problem.
There's a good chance that the instructions will work for the H370M D3H, with the following exceptions:
Good to know. This might indicate an EDID issue with the Dell or quirky firmware on the Dell. What is the Dell model number?Thanks again! I got some news regarding this issue: I ordered the Sapphire Pulse RX 580, but the issue was the same with this card. So I replaced the second 4k Display with non-Dell brand (LG) and voila - 2 Displays, both 4k, both at 60Hz and no ghosts anymore - even with the PowerColor Card. So it looks like this is a software problem (as the Dell-Displays are running perfectly well when I boot windows).
I'm using a Logitech Unifying Receiver as well on a black USB 2 port and have not encountered this problem after wake from sleep. But you might try checking on High Current.I got two small little questions: my mouse gets jerky after waking from sleep. I use a Logitech MX Master with its unifying dongle. When I hot-unplug the dongle and plug it in everything is fine again. Is there anything I can do to prevent this?
Couple of suggestions to try first:The second issue: sometimes sleep is not working. The displays goes off but the computer still is running - as I am not able to wake him up anymore I have to do a hard reset. Is there a logfile I can investigate the problem?
My LG Blu Ray burner is currently attached to the old 2008 Mac Pro. Will move it across and test it later today.Anyone with this build have a blu-ray writer working with it? My LG is not working at all...wondering if blu-ray drives need special drivers/hacks. Thanks!
I did some experimentation using a USB Blu-ray drive. I have no reason to believe an internal drive would not behave the same way but I don't have one handy.Anyone with this build have a blu-ray writer working with it?

Several comments:total newb humbly requesting help. Making dual boot. Gigabyte z390 Designare, 9900k, RTX2080. First thing I'm try to decide is which OSX version to use for everything to work (like no problems with wifi etc). Saw the video of guy building one vs mac mini, so I'm thinking I should go for 10.13 (high sierra), but am seeking all THAT OSX version selection ADVISE PLEASE and please give links to instructions. I know this is going to be a long dif thing for me but I want to try. I 'm going to go ahead and order another m.2, probably a WD Black 1TB (same as I have win10 on), unless there is some problem with that (I don't think so). If I get macos running well, I'm thinking of using m.2 ribbon cable to make it faster and easier to swap drives and be putting wear on ribbon connectors not the drives or my mb. I did the research about disabling m.2 via bios which is no a thing, etc.. still looking for ways to do that. Thanks for all the great help you give with these things !
