Displayport not working with gtx 1080, but hdmi works

Hello, I want to get my display port cable to work with my build:

CPU: Ryzen 7 3700x
Graphics: Nvidia gtx 1080
Mac OS: High Sierra (17G14033)
Motherboard: Asrock x570 Phantom Gaming 4
Monitor: LG 27ul850-w

When booting using the hdmi cable I see the Opencore boot options (screen to boot into macos or linux), but when booting with the displayport cable it just says no signal and doesn't even show the Asrock logo to go into bios.

Nvidia drivers have been updated on MacOS and everything works properly with HDMI, but using Displayport it just says no signal.

I know the display ports work on both graphics card and monitor because it works using Linux on the same computer.

Here is my EFI folder + Config.plist

Any help appreciated.
