Can't get to work internal eDP screen. HDMI works.

Can't get to work internal eDP screen. HDMI works.

Hello, im trying figuring out for about a 2 weeks how to my laptop screen get to work. After verbose it jump to black color with backlight on. It's detected in hackintool, even in settings, but all time black. What can i do to solve this? Laptop is Lenovo Legion Y520 15-IKBN, i5-7300hq with HD630 iGPU and GTX1050 2GB which ofc is disabled, Full HD 60hz screen. It's no problem with HDMI, actually it's the only way to use system with acceleration. Also, when in vesa mode (-igfxvesa), screen does normal work (so i guess it's something to framebuffer), but ofc, without acceleration and few megs of vram.

I tried EDID patches and injection, but also no result.
OpenCore EFI i work on is 0.8.7, which i made from diffrent EFI for this laptop model, but also when i did EFI from scratch on OC 0.9.9, screen didnt work. Any ideas? My EFI folder:
