I am using OC 1.0 and build EFI which is working with 1080p display resoltion. Recently I bough 4K LG monitor 27" work well with windows 11 (4k resolution 60hz) but on hackintosh I am able to get 2K 60hz only. Tried diffrent hacintool patch but failed to get 4K resolution tried both DP1.4 & HDMI1.4 (even with BD and SwithResX). Thanks in advance.

Remove framebuffer-stolenmem entry and set the DVMT to 64MB from BIOS. You should be able to get the 4K resolution.

Earlier I removed framebuffer-stolenmem and booting was stuck it because I was unable to find DVMT option in BIOS but after your comments I searched each option in bios and finally got it and set it to 64MB. Now Booted with 4K resolution. Thank you so much.

Is there any requirement to increase it from 64MB to more as I can see in bios?

Glad it works for you

There is no need for Desktops. 64MB is sufficient.
