Im having the same issue on High sierra with the pixelated graphics, anyone here that can help me get to the bottom of this? It booted into the OS once, but after a reset got the pixelated screen again.I wish you had, I probably should have asked sooner before writing that long guide, lol. the drivers just aren't there for the Vega in Sierra Apple will have will use these cards with High Sierra on their new iMacs and possibly Mac Pros.
Hi guys, I'm using Gigabyte Radeon RX Vega 64 8GB (OC Edition) on a 3x triple monitor setup on 10.13.4 final release.
Yes, outputting 2560x1440 over HDMI works.
PS: I have WhateverGreen & Lilu kexts installed but I believe it doesn't matter. I also tried Pike's Patch as suggested by @dashingncool but it did not make any difference.

I’ve been looking for hours but have come up short. But I don’t understand how it was able to work the one single time and now i just get a green square when bootingMove to Catalina or Mojave however, your card is a non reference port layout in fact it has extra ports that may not work properly or maybe shared. Also over HDMI but is it at 60hz? or is it running at 30hz?
The main issues though is your port layout not being injected correctly. If you search this forum a bit you might find someone with the same card that has already outlined how to make it work.
I really can't tell you why I can just tell you that those cards with extra ports and such are problematic.I’ve been looking for hours but have come up short. But I don’t understand how it was able to work the one single time and now i just get a green square when booting
It only has the 3 DP ports and 1 HDMI port.
I might try that tonight, I'll also be picking up that vega 64 tonight. Let's see which card works best and I'll just sell the other. Is there a how-to on putting those bios on my card?I think your problem is you should move to Mojave or Maybe Catalina. High Sierra has a very young Vega driver I had issues with a gigabyte card personally and returned it. You can try putting a Sapphire bios on the card, low risk if there is a dual bios switch.
