This shows that a desktop size of 3840x2160 pixels is being scaled to 5120x2880 (5K) over DisplayPort 1.4 with a 533.25 MHz pixel clock. So this looks normal, but the text on your monitor is probably fairly small because you've selected a "Scaling" option in System Preferences --> Displays that displays more text at the expense of that text being reduced in scale. Typically for a 27-inch monitor we'll set the effective desktop to 2560x1440 (which will scale to 5120x2880 for that clean "retina" look). This makes text more readable.

Can you post a screenshot of System Preferences --> Displays?

Thanks again. See the attached screenshot. So it looks like the display is actually driven by 5120x2880 (5K)? I got a MacBook Pro attached to a LG Ultrafine 5K and the picture looks a lot sharper. The Scaling is the same, but it looks sharper so I though the display on my hackintosh is not 5120x2880 but something below (as the "About this Mac->Display shows 3840x2160) and the display is scaling it up ...

Try clicking “Scaled” and test the various options. Is there an option that makes everything look as sharp as the MacBook Pro connected to LG UltraFine 5K?

• iMacPro1,1 uses an Intel Xeon CPU, which lacks an on-board IGPU.
• Typically we disable IGPU in BIOS when using iMacPro1,1.
• But we’ve also seen that IGPU can be enabled.
• If we disable IGPU in BIOS, then there’s no need to set any platform ID and we can delete the IGPU entry from Devices —> Properties
• If we enable IGPU in BIOS, only then should we set headless platform ID in Devices —> Properties.

• USB port configuration can be tested by running IORegistryExplorer and scrolling the device tree on left side to XHC. If you see roughly an equal number of HSxx and SSxx ports, and the total count is 15 or less, then USB is correctly configured.
• To confirm if IGPU is set up, scroll the device tree to IGPU. If the first sub-node is AppleIntelFramebuffer... then IGPU is properly enabled.
• For Thunderbolt, we should check System Information —> PCI or connect a Thunderbolt device.

When I looked in IO registry looks like I do have about 14 or so and just about an even number of both so I believe USB config is solid now, and I noticed computer sleeps and wakes with no issues it’s great. I didn’t see a section listed as iGPU so don’t know if I did that properly may have to try again I did switch myself to 19,1 prior to doing it so not sure if I maybe missed something when doing so must I only use that specific version of hackintools I used the updated version could that hAve been my issue?

outaide of that computer is running awesome iCloud and iMessages services working sleep wake and efficient now I just need tocable manage my PSU cables and I’ll be done then just plug in both monitors and good. I’m trying to get the iGPU running for decoding and encoding to use quick sync and hardware accelerated encoding for a few different services here is the build ^_^

Don’t mind the RAM change in photos went from 2666 LPX and got a hell of a deal on 3200mhz 64GB RGB Corsair pro for way less

No, 2560 x 1440 is the closest thing, but its not as sharp as the MacBook Pro/LG 5K combo.

I just swapped my "RX580" card for a "Sapphire Nitro+ RX Vega 64" card and all seems to be well, except the "About this Mac" info is wrong. Not sure what is causing this, any ideas on how to fix it?

Clover Configurator —> Devices —> Arbitrary probably has an invalid entry. Also, if your CLOVER/ACPI/patched folder has an RX 580 SSDT, it should be deleted.

Hi mate! Followed the mini guide (Catalina) and kept getting a kernel panic. Couldn't really troubleshoot on my own having read the first few pages here and everything since the mini guide. iGPU on HDMI with i7-9700K on Z390 Designare. Any ideas would be appreciated!

Also, a general question: Is there a robust way to output to a log file during boot up? I had to film at high frame rate just to see that it was a kernel panic. :/

OK, I meanwhile managed to install Catalina doing the upgrade path from Mojave using both my iGPU and my external Sapphire Pulse 5700XT. It´s been the strangest update ride I've ever encountered.

1. Installed Mojave 100% sticking to the install guide on page 1 of this thread. Installed with iGPU and HDMI Fix.
2. Went to the App Store and chose to update to Catalina. Catalina Installer prepares, running the update. Screen starts showing all the debugging stuff and went pitch black. Still on iGPU. Nothing happens from this point in time. Waited, tried a few times, same result.
3. Installed the Sapphire 5700XT, changed BIOS initial Display Output and ran again. Debugging starts, Screen went green and purple for about 5-10 Mins with a white line on top. White line vanishes and all of a sudden GPU fans stop working and screen went black again. Mainboard still on.
4. Tried again, same result, but this time I tried to hot swap the HDMI cable shortly after the fans stop. What is see is not exactly what i expected but the Catalina Login Screen on the Monitor.

So I am on Catalina 10.15.1, ATM. Seems to be working quite good with iGPU. I tried to update to the latest Beta but every time I start the Update process the Apple logo appears and the progress bar is starting but after a short while the system is rebooting into 10.15.1. again.

eGPU stops working the moment the login screen ist up and ready. Any Idea? adgpmod=pikera was missing and did the job. Fans still stop working, that might be normal under no heavy load but system idle.
