No 4K resolution on Intel HD530 on Mojave 10.14.6

No 4K resolution on Intel HD530 on Mojave 10.14.6

I'm currently running an opencore (0.5.9) vanilla install of Mojave. I recently upgraded to a 4k monitor, but the highest resolution available is 2560x1440. I have the latest version of Lilu and Whatevergreen installed. I have tried switch res, the core display patch, RDM, etc.... but no luck.

  • CPU: i5-6500
  • SMBIOS: iMac 17,1
  • Motherboard: ASUS H110T CSM
  • Monitor: LG 32un500-w

I also have the pre-allocated DVMT set to 64 mb in the bios.

I'm running out of ideas.

I have included pics of the device properties in propertree.
