[SUCCESS] Gigabyte Designare Z390 (Thunderbolt 3) + i7-9700K + AMD RX 580

I think that's normal because those two Thunderbolt ports are managed by a different USB controller (XHC5), whereas everything else is managed by XHC. Also, I do not believe that it's a USB power issue. Instead, the problem seems to be with the horizontal and vertical sync frequencies being sent to the Apple Cinema Display. This might indicate a problem with the USB-C to DVI adapter or it may require opening System Preferences --> Displays and selecting a different resolution and/or refresh rate.

hey there! look what i found :(
I think I will try another adapter xD

p.s. after 30minutes of flickering they stop to do that and works fine btw... lol

Multi-monitor functionality from iGPU is often hit or miss. It’s better to use a discrete AMD GPU such as RX570 or RX580.

I confirm something is wrong.
I've loaded defaults and started from scratch.
Windows can't even complete installation as the system continuously reboots.
I removed the GPU to see if there were differences but nothing changed and I have the feeling through the iGPU the system is even more unstable.
Loading the settings I had setup myself with a pretty high LLC and voltage I was able to complete Window installation.
Could it be the CPU (i9 9900K) or the board?

Yes this certainly means either motherboard or CPU is bad. It is more likely that motherboard is bad.

Thanks for the answer, Casey!

Yes, the two 4K monitors do seem to behave correctly when the projector isn't connected. I've done a few reboots and they were fine. Then I've connected the projector and upon reboot I got black screen on both monitors. Somehow, on one monitor i can see some very faint gray vertical lines that fade away after less than a minute. This also happened when only one screen was black after reboot.

The models of the 4K monitors are BenQ BL2711U. They support HDCP 1.4 if that's of any help. I was pretty disappointed when I found out that you need HDCP 2.2 in order to be able to play 4K material on Netflix. I wish there was a way to bypass this.

The WEG chart says it should work though I'm a little confused about what "requires HDCP and select AMD GPUs" means. Should the RX580 be compatible?

I'm not using any adapters, these monitors are connected through a DP cable, projector is connected through HDMI.
I wasn't using agdpmod=pikera at all.

Thanks!

@CaseySJ I'm noticing that the behavior varies, sometimes it boots just fine with no black screens.

I wonder, is there a way to know exactly if the graphics card is set up properly? I've noticed some weird playback issues with Metal in Premiere Pro.

Hi @CaseySJ
I installed Catalina, but Graphics don't work correctly.

<< Solved >> - RX 580 Graphics Problem

I installed Catalina, but Graphics don't work correctly. 1. In Unibeast Graphics Configuration Step, I didn't select ATI. Did I have to select ATI for RX 580? 2. This is my CLOVER and Library/Extensions(I copied AMD9500Controller.kext and WhateverGreen.kext) How can I solve this?

Any advice?

Sure, I’ll give you a modified CLOVER folder in the original thread shortly.

Does your workflow require the projector to be connected all the time? If the projector is only used occasionally, one can connect it after the system has booted.

Something else to try would be to connect the three displays to a real Mac if possible and observe the behavior during startup.

Yet another option is to check the projector’s owner’s manual for any recommended procedures for connecting to a PC.

And yet another option would be to try Platform ID 0x3E9B0007 and connect the projector via onboard HDMI. This would also require adding the HDMI frame buffer patch.

I could definitely disconnect/connect the projector at boot but ideally i'd like that to not be necessary. I use this projector everyday either for working or watching stuff. Not a huge issue right now but I'd like to fix that in the future.

Offtopic : I'm trying to clone this build onto another SSD and your guide specifies that I'd need to use a SSD of the same size. Is this mandatory? I'm trying to clone the OS installed on a 256GB SSD onto a 1TB SSD.

Thanks!

The backup drive does not have to be the same size as original. It should be at least as large as the amount of data to be backed up.
