UHD 630 - Can't boot with a 4K monitor, but 1080 monitors are fine

[jamesst20]

Hi,

My problem is that my build works perfectly with a single or dual 1080p monitor, but wont boot with a 4K monitor. If I boot with a 1080p monitor, then connect my 4k monitor, my CPU starts running, than the screen goes black and the computer freeze forever until reboot. I am running Mojave 10.14.4

Has anyone a suggestion?

Here is my full build with what steps/kexts I used : https://www.tonymacx86.com/threads/...te-z390m-gaming-intel-uhd-630-i7-8700.277121/

Quoting the important part:

Hardware

• Intel Core i7-8700
• Intel UHD 630
• Gigabyte Z390M Gaming (Micro ATX)

What works

• Internal IGPU Intel UHD 630 (HDMI & DVI) with QE/CI acceleration
• Shutdown / Reboot / Sleep
• Sound (AppleALC - Audio ID 1)
• USB Ports
• Pretty much anything

Fixing GPU

Removing in Clover all HDMI, Intel patches and ID.
IntelGFX-> Empty, ig-platform-id->Empty, Inject Intel->Disabled, etc
Installed latest WhateverGreen

Used the Z390M patch for Gigabyte at the bottom of this thread : https://www.tonymacx86.com/threads/...ching-guide-hdmi-black-screen-problem.269149/

Thank you
James

Just a little small bump to increase visibility

Is there any solution other than buying an RX 580?

@jamesst20,

To use a 4K display with IGPU you need to apply WhatEverGreens pixel clock patch.

Just make sure you have Lilu + WhatEverGreen Installed and add -cdfon as a boot argument to your config.plist.

    <key>Boot</key>
    <dict>
        <key>Arguments</key>
        <string>........ -cdfon</string>
        '
        '
        '
        '
    </dict>

Or use Clover Configurator :-



Cheers
Jay

Thank you, it did not have any effect, so i though maybe updating to latest WhateverGreen.

That was a mistake, I am stuck at "gioscreenlockstate 3" when booting.

Disconnecting the monitor and reconnecting it 5 seconds later let me reach the lockscreen, but only one monitor works and it's pink.

Any idea?

Edit : Tried SMBios 18,1, not results, but 14,1 did fix the black screen (lockstate 3), but the screen is still pink

Okay, everything is still up to date and it's running fine.. it was a kext caching issue.

However, my 4K problem is still not resolved

Thanks for the reply, the UHD 630 meets my needs. Honestly if I had to invest I would get the RX 570 which is the cheapest native support GPU I know.

RX560 is supported.

RX560 is supported.

It depends on the brand you get, some of them like XFX won't work. It's also not "officially" supported : https://support.apple.com/en-us/HT208544

Supported enough to work and have rx 560 in the system information. I used it for some time while GPU prices were off the hinges. XFX also has issues I think with 570 and 580’s
