Unable to install Catalina on a fresh Hackintosh

Hello,

I made a Hackintosh yesterday.

Here are the specs :

Gigabyte Z390 DESIGNARE Sapphire NITRO+ Radeon RX 5700 XT 8G SE

Intel Core i7-9700K (3.6 GHz / 4.9 GHz)

G.Skill Aegis 32 Go (2 x 16 Go) DDR4 3000 MHz CL16

Samsung SSD 860 QVO 2 To

I think we don't need to know more about the specs.

I made a USB Installation from Catalina (My MacBook Pro) I used https://www.tonymacx86.com/threads/...390-thunderbolt-3-i7-9700k-amd-rx-580.267551/ to set the BIOS Settings

But when booting from Clover to Mac OS Catalina Installation , I see the Apple Logo, it loads and goes black screen after... I can't do anything :(

I tried to make the USB stick again with Catalina, I injected ATI Drivers (don't know why but I tried)

When I use a DisplayPort with 4K monitor, it just goes black screen during apple logo

With HDMI 1080p , it just black screen and reboot to windows....

What can I do ? I'm a beginner on Hackintosh

Thanks in advance !
