Alright thank you! I have some good news and bad news. My build is
almost perfect.
I updated my bios settings to reflect the guide (they mysteriously had reset to defaults) and all my USB ports and thunderbolt ports work w/ hot swap
except for my LG 5k display, which I'm OK with as I'm just happy its running successfully in full 5k res. I have also successfully put my build into headless mode.
However I have new problems:
- All my USB devices eject during sleep (I believe I saw talk+solution about this in the guide, so I will revisit it).
- I have very unusual and deal-breaking behavior with my LG 5k display. I'll try to break it down here.
- I have my Vega 64 plugged into the Mobo DP port and my LG 5k display boots the bios screen and clover, so everything works great in that sense. So my Vega 64 is driving my LG 5k, not the HD 630
- During Mac OS boot I get an intermittent black screen during the apple boot logo and after the purple WEG marks (I assume this is normal). Sometimes, only when using the LG 5k display, it goes to black screen and stays black. The login doesn't pop up as it usually does. The LG 5k display doesn't turn back on at all. The builds' fans acts as if it has in fact boot into login screen, though.
- After I get the black screen, I can't get the display to show anything no matter how many reboots. The bios or clover don't even show up anymore. What seems to fix it is connecting to my Vega 64 via DP or HDMI to another monitor and then setting it up to use my LG 5k again. But this fix only lasts so many reboots. Usually after 5-8 reboots, the LG 5k stops working again and I have to go through this whole process to make it work again.
- Hot swapping the LG 5k in while I have my Vega 64 plugged into a separate monitor doesn't work either. It just is a black screen and before I made macOS into headless mode sometimes would display lines. But after I enabled headless mode that isn't an issue anymore-- its just a black screen. Im not so much worried about the LG 5k hot swapping as I am it not working consistently.
- The monitor stops working completely (including stops working in bios boot up) even if I unplug or bump the monitor while macOS is booted up. And sometimes when I reboot my PC after this happens-- the PC reboots twice before booting into clover. Thats something interesting I thought I should point out.
So any ideas on making my 5k display work consistently? I couldn't find anybody else in the forums who had similar problems. This is so irritating as its perfect when it is working. All other displays work consistently every single time every time. I have included a set of screenshots, but also a copy of my IORegistryExplorer file.
Also I just want to verify something: I was able to put my build into headless mode as shown by my VideoProc acceleration confirmation of H264 and HEVC with my HD 630 graphics. This still means my Vega 64 will be used for FCPX and all other video intensive tasks as an iMac 19,1 would, correct?
Extra Info if at all useful:
- Clover 4920
- Windows is installed in NVME slot 1 (but have never boot into windows on this PC this far)
