mini display port to hdmi not working mac

Creating a new EDID file like here, which resulted in the monitor staying black.A Mini Display Port to Display Port adapter and a Mini Display Port to Display Port cable, which resulted in the 'no video output' on the monitor.Different Mini Display Port to HDMI adapters and a Mini Display Port to HDMI cable without adapter.Preferences -> Displays -> option-click on Scaled.With an Mini Display Port to HDMI adapter or cable the monitor works but with a maximum resolution of 1080p. Unfortunately with a Mini Display Port to Display Port adapter or cable the Mac does not recognize that there is a external monitor and the monitor just outputs 'no video output'. Is there something that i'm missing or is it just unsupported? thanks to anybody who wants to help meI just bought a Phillips 245B monitor with QHD (2560x1440) so I could run it in native resolution with my MacBook Pro (15-inch, Mid 2010) and its NVIDIA GeForce GT 330M GPU. I added my full current EFI folder with the ist file containing, in the DeviceProperties section, all the patches i added using whatevergreen's guide. also, hackintool doesn't even recognize the gpu and labels it as '?' in the system info tab. I followed the whatevergreen intelHD patching guide for my generation but it makes no difference.

i tried taking a look at the connectors in hackintool but no ports show any sign of external connection, except for the main pc display. nothing shows up in the display preferences, the monitor doesn't wake up like it normally does for windows, the screen stays the same. The problem is, when i plug the cable in it doesn't recognize anything. so i decided to try and connect a HDMI monitor (the same one i use flawlessly for windows 10) via the mini DisplayPort on my pc, using a mDP-HDMI adapter. i tried every way in the world to fix that but it just seems like it's not possible.

Hey so basically i somehow built a noob catalina 10.15.7 hackintosh in the past few weeks and everything has been working fine except for one thing: my laptop (surface pro 4)'s resolution is not supported, so the GUI elements are very small. Building a CustoMac Hackintosh: Buyer's Guide
