BigSur - Ventura 5120x1440 resolution ISSUE

Hi friends,

I recently purchased a new 49-inch monitor (no brand), and I'm facing a resolution issue on my Hackintosh system. On my previous macOS Big Sur installation, I was unable to get the full 5120 resolution, even though the monitor supported it and worked at this resolution on a live USB Ubuntu.

To try to fix this issue, I upgraded to macOS Ventura, but unfortunately, the problem persists. Also I got new problem with loading 5min on login screen…. Here's my current hardware configuration and the kexts I've updated:

Hardware Configuration: - Motherboard: MSI Z490 Tomahawk - GPU: RX 580 - NVMe: Samsung 970 Evo - RAM: 64GB DDR4 3666MHz - CPU: i7 11700f - Monitor: 49-inch (no brand)

Updated Kexts: - AppleALC.kext - WhateverGreen.kext - Lilu.kext - VirtualSMC.kext - AirportBrcmFixup.kext - USBPorts.kext - IntelMausi.kext - LucyRTL8125Ethernet.kext - XHCI-unsupported.kext

SMBIOS Configuration: - Using iMac Pro (2017) system definition

I tried adding Lilu.kext + CoreDisplayFixup.kext and followed the standard procedures to repair permissions and rebuild the cache, but I'm still stuck at a maximum resolution of 3820 pixels.

Has anyone else experienced this issue? Any insights, suggestions, or specific configurations that I might have missed would be greatly appreciated.

I've been working on this for a while now, and it's been a challenging puzzle. Thank you all in advance for your assistance and guidance!
