Hi @CaseySJ Thanks for your reply, please see my responses below.
(1) Yes I have tried both 18,2 and 18,3, both are unusable - flickers, artifacts and the screen unresponsiveness.
(2) I am using DisplayPort, will not use the other connectors.
(3) Computer monitor is the LG 27UK850-W. Full 4K works ok on Windows 10

(5) Thanks, will do.
1. You are currently using iMac18,1 and the SMBIOS section of config.plist is not fully filled out. Have you tried iMac18,2 (Retina 4K) or even iMac18,3?

2. Are you driving the LG monitor with DisplayPort? Your Platform ID is set to 0x59120000 with all connectors as DP, so HDMI most likely does not work. Or are you using a DisplayPort to HDMI adapter?

3. What the model number of the LG monitor? Is it flat screen television or a computer monitor?

4. Please post a screenshot of: System Information --> Graphics/Displays. This will provide more information about the monitor and the properties of the monitor.

5. The i5-7500T is a Kaby Lake processor, so the Azul Framebuffer patch in Kernel and Kext Patches will not have an effect. It's okay to leave that in place, but probably better to check the Disable flag.
