baconeveryday Posted October 29, 2023 Share Posted October 29, 2023 Hello, System has UHD 630 and running Ventura 13.6.1. Current displaying is only showing 2K (default) as the highest resolution. I'm unable to get 4K working. It is configured for iMac 19,2. Current settings follow: https://dortania.github.io/OpenCore-Install-Guide/config.plist/coffee-lake.html#booter Key Type Value AAPL,ig-platform-id Data 07009B3E framebuffer-patch-enable Data 01000000 framebuffer-stolenmem Data 00003001 Any suggestions are appreciated.
