Mac mini - Razer Core X Chroma - Unable to boot?

I've been using a Blackmagic eGPU Pro for a while, but recently purchased a Razer Core X Chroma with an MSI 5700 XT (the gaming model) GPU.  I'm running this with a loaded up late-2018 mini running Catalina 10.15.4.

With the eGPU powered on and connected to my mini (no display connected directly to the mini), I get nothing.  Black screens on the monitors.

If I let the system boot up with the eGPU off (I used a TV connected to the HDMI port on the mini to see it boot up), and then turn the eGPU on afterwards, voila!, everything works fine.

Is there anything I can do to get this to work on boot too?

@ryan_ruel, Common issue. Consider upgrading to 10.15.5 which apparently might have resolved the issue.

Ooh, nice.

Glad it's not just me. Smile

Edit:  I see it was literally released yesterday.  Updating now.

Nice, 10.15.5 fixed the problem for me!

eGPU now comes up fine after a cold boot or restart (FileVault disabled, of course).

@steve4332, I wonder if you get different behavior with a display that is not 5K or one that is connected to the eGPU instead of the Mac mini?

It's actually a 4K display just using scaled resolution. Smile It is connected to the eGPU.

@steve4332, oh, right. An LG UltraFine 5K would say something other than "LG Ultra HD". I hate that macOS only shows framebuffer information and not output signal information.

Just for reference, I'm using two LG 32UL950-W monitors with mine.
