Black or noisy screen

[acasas]

Hello, I'm trying to install Catalina with opencore legacy installer but when installer should be displayed then in HDMI i'm getting a black screen (display is detecting signal) and if I try with a display port i got a noisy screen (img attached)

I have a fx 8120 cpu and a gigabyte rx 580 (rev2), can anyone help me? thanks in advance

I also attached my efi config and opencore logs

Check your BIOS for an update. This looks like the same issue I had with a buggy version of AGESA.

Hello @Shaneee , my motherboard it's and oldie one (aus crosshair v formula) the latest version of the bios is from 2012... do you know if there is a way to update AGESA manually or if the error I reported could come from another place?

PD: I tried with different BIOS versions (with different agesa version) from a MODED bios from here https://www.win-raid.com/t2200f44-OFFER-Asus-Crosshair-V-Formula-mod-BIOS.html
