Hackintosh Catalina nvidia screen resolution issue

Hello,

This is my first hackintosh build.I am running catalina 10.15.5Intel i5 4th gen (Haswell)Asus B85M-K motherboardnVidia geforce 210 graphics card (using HDMI cable connected to this as motherboard doesn't have a HDMI port)8 gb ddr3 RAM

After days of research I was finally able to install mac os using this guide (opencore).The issue is the resolution is 1280x1024.I am aware that nvidia drivers are not supported on catalina.And I don't care about the graphics acceleration. I just wish to have full HD resolution.I have tried patching the drivers of high sierra versions with no luck.

I have tried physically removing my graphics from my motherboard and trying to run only on my iGPU intel HD 4600.But it always gets stuck near

IOConsoleUsers: gIOScreenLockState 3, hs 0, bs 0..... 

Also my motherboard does not have its own HDMI port (only VGA and DVI), I use the HDMI port on my graphics card.

I would owe my life to someone if they are able to help me in this.I assume I have 3 options :

1. Try to figure out/patch dGPU drivers.
2. Remove dGPU (use VGA cable) and apply settings that my iGPU will be used for everything.
3. Keep my dGPU plugged in and apply settings make use of my iGPU.

Also my on board audio (Realtek® ALC887) does not work.Please note that its been days I have tried to figure out ways using all three options with no luck. Please find My Config.plist file and help me. PLEASE provide steps what needs to be done.
