Gigabyte Z490 Vision D (Thunderbolt 3) + i5-10400 + AMD RX 580

[CaseySJ]

ViewSonic 2758 2k and ViewSonic 2785 4k. The problem with unstable video output occurs both of them. (at the same time, z390 designare with Radeon VII use these displays perfectly).

From the first boot after macos install. I have fresh OS.

I have fresh new installation, OC 0.7.2, EFI for Vision G is from Hackindrom.

Nope, DP shows 1080p on 2k display. If i try to reconnect or switch displays, it can becames black (but OS is running normally, i can see it by Anydesk)

In System Preferences --> Displays can you manually change the resolution to 2K?

Ok, i will get rid of it.

For the Vision G F6 or F7 is better? Do they have CFG-Lock parameter, right?

Gigabyte's USA website does not have BIOS F7, hence I recommended BIOS F6. I believe it has CFG-Lock in the Boot section. Also we must disable Serial Port.

Hello @jimbojingle,

Let's start from the beginning on this issue. Some basics first:

• Which version of BIOS is installed on your Z490 Vision D?
• Is the Thunderbolt firmware flashed?
• What is the make/model of your GPU?
• What is the make/model of your monitor?
• Which video connector are you using? HDMI, DisplayPort, DVI?
• What other PCIe cards are installed?
  • Fenvi WiFi/BT?
  • Anything else?
• What devices are connected to the internal USB 2.0 headers?
  • Fenvi Bluetooth?
  • Anything else?
• What Thunderbolt devices are connected to the system?
• What are the makes/models of all NVMe SSDs in your system?
• In BIOS, is CSM Support enabled or disabled?
• In BIOS, is Thunderbolt Boot Support enabled? If so, what is it set to? Boot Once? Boot ACL?
• Have you already tried re-flashing the BIOS?
• Have you already tried CMOS Reset?

Hi CaseySJ,

Thanks for your continued enthusiasm to help. I really appreciate it.

It would be really great to resolve my 'Hanging at the Gigabyte Splash Screen' problem which has been present since build day one and plagues me on a daily basis. I have discussed the problem with Gigabyte to no avail and have had my Corsair Vengeance RGB Pro RAM DDR 4 (4 x 16GB) tested and verified by Corsair.

Thanks again for taking a look at this.

Have you tried it without the extender cable? I have had no end of trouble with cheap PCI extenders and they have all ended up in the bin.

Did you disable ResizeBar in Bios?

Check your cable, SATA cable, and Power cable to SSD disk.

In System Preferences --> Displays can you manually change the resolution to 2K?

No, top resolution is 1080p, if i use DP.

Gigabyte's USA website does not have BIOS F7, hence I recommended BIOS F6. I believe it has CFG-Lock in the Boot section. Also we must disable Serial Port.

I flashed F6, disabled iGFX, chose PCIe 1 output. Disabled Serial port and CMS.
With DP i boot into Open Core, picker has low resolution and distort. After picker it boots in black screen. Anydesk shows OS working fine, with right display resolution (but output is black).
Same thing on every of three DP outputs on RX580.

HDMI output works as expected, OpenCore picker has right resolution also.

@jimbojingle,

I was about to suggest the same thing...

Some questions/suggestions:

• Which version of macOS are you running?
• Are you using a good DisplayPort 1.2 or 1.4 cable?
• Which monitor are you currently connecting?
  • ViewSonic 2785 (4K)
  • ViewSonic 2758 (1440p)
• Are you connecting both monitors at the same time, or just one? It's best to connect only one monitor for this test.
• From the on-board menu please disable MST or Multi-Stream Transport if the option exists.
• If the on-board menu on the Viewsonic has an option to choose DisplayPort 1.1 or DisplayPort 1.2, please try "DisplayPort 1.1" first then try 1.2.
• If the monitor's on-board menu has "Factory Reset", please try that also.

It is really strange, but I discovered that the video output goes back to normal, if I turned integrated graphic ON. I keep Initial Display Output ad PCIe 1st, and use SMBIOS iMac Pro1,1 (iGPU is not listed, even if it is turned on). Display is attached to dGPU output.

How can it be?

 

[lightmanrt]

change your SMBIOS to MacPro1,1. Then disable iGPU or make it computer only, use only dGPU. So you can play Lossless/ Atmos/ Netflix on Safari, AppleTV

I have been using Macpro1,1 for years with no problem with Apple TV or music. Switching to any of the other iMac SIMBIOS always introduces problems especially with Apple TV in particular.
